INTRODUCTION

SAFETY COPYRIGHT LICENSE AGREEMENT

Please consult the safety instructions copyright and license agreement on the first pages of the manual

CNC WITH WINDOWS OPERATING SYSTEM

The CYBELEC DNCs equipped with Windows have been installed in the factory with a configuration specially realized for the numerical control see technical information

This configuration ensures that a minimum of files are present on the DNC offering in this way a maximum speed to execute the programs This configuration also ensures that the drivers are correct and that the whole guarantees an optimal functioning of the numerical control

As Windows is a very open system it is advised not to modify the Windows installation nor to install other programs You risk disturbing the functioning of the numerical control

If you wish to install a network or a printer please call a specialist

Remember that the DNC is equipped with a CD-ROM reader and that it is very easy or even tempting to install external software utilities or games coming from specialized magazines

CYBELEC accepts no responsibility in case of malfunctioning of the numerical control if other programs have been installed or if the original configuration has been modified

We also remind you that the Windows environment is infested with viruses and utmost caution is to be taken when using data or software coming from outside A regular backup enables you to keep your data safe

PAGE 8 USER GUIDE PC/DNC 1200 2D 3D . QUICK START
Thís chapter descríbes, Ьy means of some símple examples, díverse ways of
usíng your DNC.
L-alpha Prograimning.
Thís method ís the fastest and the most currently used in the workshop when the operator has to create himself a product from a paper drawíng.
Direct Programıníng.
Thís type of programming ís often used for siınple products or by operators havíng worked on conventìonal pressbrakes without numerical controls.
Thís page is very close to what an operator has to do, sínce he has on one single screen all the information and fıelds necessary for the prograınıníng of hís product.
3D Programmíng.
Thís type of programmíng enables the user to vísualize the construction of its product in 3D. This mode also enables more elaborated constructíons and modífıcatíons than ín 2D mode.
We assume ín thís part that all the necessary tools have already been programmed as well as the machíne parameters.
Access levels We presume that the operator knows how to reach level 1, oг that the key of the front pane1 optíon ís on positíon 1. Should thís not be the case, see chapter Protectíon of the Access Levels further in this manual.
The screens of this manual have been captured wíth the PC 1200 Windows software. The screens however are ídentícal in the DNC 1200 2D.
Reminder:
You will find the correspondence between the keys of the DNC and those of a PC keyboard іп the 2D Reference Manual under External keyboard.
These procedures índícate to the operator a programmíng method recommended by CYBELEC, enablíng to assímílate by the example the functioning of the software.
For addítíonal ínformatíon, please consult the 2D Reference Manual and/or the 3D Reference Manual, which each contaíns a table of contents and a detaíled índex facílítatíng the search for ínformatíon.

QUICK START PAGE 9 LEAVING THE SOFTWARE .
It is possíble at any tíme to quít the task after havíng memorized the current state. However ít ís important to leave the software in the correct way by F1
callíng up the MENU page and pressing the QUIT key.
Alt The same procedure can be used on the PC software, oг press the F1 keys on any page.
PAGE 10 USER GUIDE PC/DNC 1200 2D 3D. L-ALPHA 21D PROGRAMMING
Thís chapter descňbes, by means of a concrete example, how to create a product by usíng the L-alpha method length-angle .
Thís method ís fast and easy and allows to dísplay the product in 2D, which usually ís sufficíent when products are beíng programmed ín the workshop.
The product beíng used as an example ís composed of 2 sectíons profıles , but the procedure ís ídentícal for one or several sections.

When introducing the data in L-Alpha mode, just begin the profıle by one of the extremíties and furnísh oпe after the other the values of each face and angle. At the last face there ís no angle corresponding to.
Remark: As shown ín the following fıgure, the profíle of sectíon 1 ís automatícally drawn as a function of the introduced data length and angle , thus the value of the ínternal radíus ís automatícally calculated.
Automatícally drawn profıle
Procedure:
Place the cursor on the first fıeld of the LENGTH columm and introduce the value of 45 mm which corresponds to the fırst length.
Place the cursor oп the fvst fıeld of the ANGLE column and introduce the value of 90 whích corresponds to the fırst angle to be bent.
Pl.ace the cursor on the second fıeld ofthe LENGTH column and íntroduce the value of 200 mrn whích corresponds to the second length.
Place the cursor on the second fıeld of the ANGLE column and íntroduce the value of 90 which corresponds to the second angle to be bent.
Place the cursor on the thírd fıeld of the LENGTH colunin and íntroduce the value of 45 mm whích corresponds to the last length before the edge of the product.
This way of operatíng is much faster.
PROGRAMMING SECTION 2
The defınition of the bending dírectíon is done by inversing the angle sign,
however the choíce of the síde is arbitrary, but has to be constant for the
whole profıle of the product.

Procedure:
Stay on PRODUCT NUMERICAL page.
Place the cursor on the SECTION field, enter the value of 2 and leave the field. Thís automatically ínítialízes a new page for programming sectíon 2.
Place the cursor on the BEND L. field and enter the bending length for this section 200 .
Place the cursor on the first fıeld of the LENGTH column and íntroduce the value of 30 mm whích corresponds to the fırst length.
Place the cursor on the fırst fıeld of the ANGLE column and introduce the value of 90 which corresponds to the first angle to be bent.
Place the cursor on the second fıeld of the LENGTH column and íntroduce the value of 40 mm which corresponds to the second length.
Place the cursor on the second field of the ANGLE column and íntroduce the value of -90 whích corresponds to the second angle to be bent.
Place the cursor on the thírd field of the LENGTH column and íntroduce the value of 150 mm whích corresponds to the third length.

After this the succession of sequences can be vísualízed using the PgUp Pg Dn and keys.
In the just programmed example we can see that the searchíng for the bendíng range has fırst placed the sectíon 1, and then the sectíon 2.
The operator has the possíbílíty to modífy the bendíng range see the conesponding chapter in the 2D Reference Manual or to ask the software to respect specífic critería like minimum of swíngs or returns. For that, please refer to the 2D Reference Manual, section
In case where the software program does not find any solutíon, the bending range must be ímposed manually.
See Bending order ín the 2D Reference Manual.

It can be seen that the axis posítíon, the bendíng force, the crowning and, if applícable, the retractíon and the top dead centre dependíng on how they have been defıned ín the machíne parameters are calculated automatically.
These values can be modifıed by the operator.
According to his needs, the operator can modífy the followíng ítems:

TDC the Top Dead Center If not programmed the beam will rise to the maximum TDC

RETRACTION BG the retraction of the backgauge

SP the Switch Point switching from High Speed to Bending Speed

DWELL TIME the time during which pressure is being maintained

BENDING SPEED the bending speed downward or the speed during the upward moving phase until the clamping point is reached

LOW SPEED allows to define that only a portion expressed

DISTANCE in of the upward movement between the TDC and the clamping point will be carried out at low speed the continuation of the upward movement is made at high speed

Complementary explanations are found in the 2D Reference Manual

the required angle the Y depth will be calculated according to the tools and the materíal already programmed . It ís also possíble to dírectly enter the Y 1/ Y2 values wíthout programmíng the angle.
the real posítíon of the backgauge.
the specifıc data for the current sequence top dead center, bending length and, íf necessary, backgauge type, retractíon, dwell tíme, etc.

RETRACTION BG + CROWNING + 3
BENDING WIDTH BENDING FORCE TON
SP DWELL TIME SEC
START AXES AUTO BENDING SPEED
LOW SPEED DISTANCE

The page shown above illustrates how to program the two flaps with the oblong holes in section 1.

The two bends being identical, enter 2 in the CY field. Program the angle to 90°, the X axis to its absolute value, and enter the bending length 150.

The bending force and the crowning will be calculated automatically. The operator can, of course, modify these values if necessary.

According to his needs, the operator can also modify:

TDC the Top Dead Center. If not programmed, the beam will rise to the maximum TDC.

RETRACTION BG the retraction of the backgauge.

SP the Switch Point switching from High Speed to Bending Speed.

DWELL TIME the time during which pressure is being maintained.

BENDING SPEED the bending speed downward, or the speed during the upward moving phase until the clamping point is reached.

LOW SPEED DISTANCE allows defining that only a portion of the upward movement between the TDC and the clamping point will be carried out at low speed; the continuation of the upward movement is made at high speed.

DIRECT PROGRAMMING PAGE 29

ENTERING THE DATA 2

HINT The way of programming described above in section Entering the Data 1 requires the operator to subtract the steel thickness from the external dimension of the product. The procedure described below will facilitate the programming. It has, however, some limitations depending on the product and the chosen bending order.

The hint consists of entering the external dimension in the X field of the backgauge and programming a constant negative correction corresponding approximately, according to your experience, to the tools and the material thickness for the entire product.

This procedure is described hereafter:

The BEND NUMERICAL page contains the same remarks as the preceding screen illustration, except for the fact that X has been programmed with the external dimension, as explained.

This sequence carries out the bending of the two flaps with oblong holes.

To create the subsequent sequence, press the ACTION key and choose COPY BEND.

It can be seen that all the data has been copied onto the second sequence.

If necessary, correct the flap in this example, a correction of X=- is assumed for the current bend.

Reminder: In the above screen page, the correction of mm corresponds to the material thickness programmed in the example Entering the Data 2 above.

Position the cursor on the ANGLE field, BEND column, and enter the measured angle in this case. The software automatically calculates the necessary correction, which can be seen in the Y1, Y2 fields, in the BEND column. Also see the 2D Reference Manual in the Corrections section.

Carry out a second test bend on the same sequence with a second test product. If necessary, make a new correction.

Depending on the material, the machine adjustment, and the accuracy
of the data introduced, 2 or 3 corrections can be necessary for a bend.
This can be considered as being a normal situation.

Otherwise, a message indicating that the user is not authorized is displayed.

Once authorization is acquired, the operator can change the level among those authorized to him without requiring a new password request.
For instance, a user with access on level 13 can navigate between levels 1, 2, and 3 without having to give his password again.
If level 10 is activated, access to any other level will require entering the password again.
This request will also appear when the user passes to a superior level, from 0 to 1, from 1 to 2, from 2 to 3, etc., and he has no access authorization.

Advice: If you have accessed level 13, access to level 10 after your intervention. This will avoid making undesired changes by inadvertence.

INSTALLATION OF THE PC/DNC 1200 SOFTWARE
There are 4 types of installation to distinguish:

Installation of PC 1200 Windows on a PC station.

Installation of PC 1200 DOS or PC 900 DOS on a PC station equipped with Windows.

Installation of the DNC 1200 Windows software.

Installation of the DNC 1200 DOS software.
(Only certain software for press brakes exist in DOS versions.)

PC PROTECTION KEY
The key must be equipped with at least options 20, 25 to authorize PC 1200 to work.
The protection key must be installed on the parallel port LPT1 of the printer.
If a printer is connected to the computer via the key, it must be switched on.

Important Note:
Do not connect the protection key to a serial port, as this may destroy the key.
Always switch the PC or DNC off before connecting or disconnecting the protection key.

KEY CONFIGURATION TROUBLESHOOTING
If the key is not recognized, the message "ILLEGAL CONFIGURATION" will appear.
In this case, leave the software, and perform the following troubleshooting steps:

Verify that the key is connected to the printer port LPT1.

Ensure only the protection key is connected, without any printers or other peripherals.

Install the Sentinel driver from the CD directory under \Tools\Win_NT_2000\DriversNT359.

For Windows NT, 2000, or XP, you must have a Sentinel Super Pro key, which is distinguishable by its size (see the photo).
If the issue persists, check if a RAINPORT driver is required for Windows NT, 2000, or XP, located in the \Tools\Win_NT_2000\Rainport directory on the CD.

If these steps do not resolve the issue, check the configuration of multiple keys o

It looks like you're sharing some documentation related to the installation and setup of software for a PC/DNC 1200 system. Here's a summary of the steps and information provided in your text:

Key Points:

Protection Key Setup:

A protection key must be installed to activate certain software options.

If the protection key is not recognized, try using another PC with a different operating system (e.g., Windows 95, Windows 98).

If the key is still unrecognized, it could be damaged and needs replacement.

In a network configuration, the software can be installed on the server, but each PC running the software requires its own protection key.

Minimum System Requirements:

CPU: Pentium 100 MHz.

RAM: 32 MB.

OS: Windows 95/98/Me/NT4/2000/XP.

Display: 800x600 resolution, 16-bit color (65,536 colors).

Software Support:

The software is supplied via CD-ROM for both PC 1200 and DNC 1200 versions.

For Windows installations, the Sentinel driver must be installed from the directory on the CD.

Some versions of Windows (like NT, 2000, and XP) may experience mouse issues or crashes due to software incompatibility.

PC/DNC 1200 Windows Version:

When installing the software, follow the on-screen instructions and choose the appropriate configuration disk if prompted.

If upgrading from an older version, the software will ask if you want to install the new configuration disk or use the old one.

Installation in Windows NT, 2000, or XP:

Administrator rights are required to install the software.

You must install Sentinel drivers before starting the PC 1200 software.

If the software doesn’t recognize the key, you may need to install additional drivers such as "Rainport" from the CD.

Installation for DNC 1200:

Ensure that Windows is installed on the DNC system before proceeding.

A keyboard should be connected, and BIOS settings must be adjusted to "Halt on all but keyboard" to avoid boot issues.

DOS Installation for DNC 1200:

The DOS version requires system disks to install the software on the DNC.

If you choose to format the device, all existing data will be lost.

BIOS configuration adjustments may be necessary to ensure proper booting.

Troubleshooting:

If certain features or components (like the keyboard) are not working after installation, ensure that the BIOS setup is correct (e.g., "Halt on all but keyboard").

Always remove any installation disks after the process is completed.

General Troubleshooting Tips:

Protection Key Issues: If the protection key isn't working, try a different PC or a different operating system. If it still fails, the key might need replacement.

Slow Performance: Under Windows 2000/XP, the software may run slowly or experience crashes when using the mouse—no solution has been found for this issue as of the document's last update.

Mouse Issues: If the software is slow or crashes when using the mouse, try using an earlier version of Windows (95/98/Me).

This guide covers how to install the necessary software for the PC/DNC 1200 system, troubleshoot installation issues, and configure the system for use. Let me know if you need help with any specific part of the process!

Here’s the revised text with the mistakes corrected, as per your request. I've kept everything the same, just fixing typos and formatting:

DEFINITIONS

ABS
Page: BEND NUMERICAL
This round robin list is placed next to the name of the axis of the X stop.
Two choices: ABS and REL.
ABS indicates that the X axis functions in absolute mode.
This means that the destination of the axis is an absolute distance measured from the die V.
Absolute mode is selected by default.

See REL below.
Example: MEM POS
X ABS
Omm 120mm 190mm

REL
REL indicates that the X axis functions in relative mode.
This means that the displacement programmed is made starting from the actual stop position.
Generally, a negative value is programmed.
The relative mode is often used with the cycle repetition CY 2 at 99.
For example, with a punching tool, you wish to make 5 holes equidistant from the first location of the first hole.
The second sequence will be programmed in relative mode
X REL with a cycle repetition equal to 4 CY 4.
Example: MEM POS
X REL
Omm mm mm

DEFINITIONS PAGE 11
Remark: It is not possible to use the relative mode on the first sequence.
If such is the case, an error is generated when changing mode AUTO, SEMI-AUTO and the message DEPL. X REL. IMPOSSIBLE is displayed in the interactive field.

ACTIVE PERIPHERALS
Page: WELCOME
Aim:
This function allows choosing the peripheral containing the required information separately for the machine parameters, the products, the tools, the CAD files, and the complementary files on the product information page.
It offers a multitude of combinations especially appreciated on a PC workstation. Effectively using these choices, the operator could easily manage several machines.

The comprehension of this notion is important, as its flexibility allows a large diversity of choices.

Definition:
The active peripheral is the peripheral in which the software is going to read, search, save, or delete data. The active peripherals are designated on the WELCOME page.
On certain pages, another peripheral can be temporarily selected for an operation (e.g., PRODUCT LIST, PROGRAMMING PUNCHES / DIES, TRANSFER).

Active Peripherals Machine
When you change the peripheral in the MACHINE field, automatically PRODUCTS, PUNCHES, and DIES are redirected to the same peripheral.
To change them independently of each other, you must simply modify them afterward.
The CAD FILES and COMPLIMENT peripherals are not modified automatically, as they are generally situated on a network and are often the object of a specific classification in one or several directories.

By modifying in this way the MACHINE peripheral, the environment of the software becomes that of another machine. It is thus easy to simulate products for different configurations of press brakes.
Also, more and more, you will find diskettes containing examples of special products supplied by CYBELEC or by the machine manufacturer for which the realization needs a special tool (for example). With this possibility, you can thus easily visualize these demonstrations with all the machine context in which they were created.

On a numerical control, it is evidently only possible to work with a machine when the MACHINE field is switched to INTERNAL.
If another peripheral is used to visualize a demonstration product, for example, it will still be possible to switch the DNC to semi-auto or auto mode.

PAGE 12 2D REFERENCE MANUAL
However, the ENC NOT CONNECTED will appear, and it will not be possible to reach the machine.
To reactivate the INTERNAL machine peripheral, you must:
Select MACHINE INTERNAL.
Initialize the ENC by pressing INIT ENC, Action menu.

Active Peripheral Products
Selects the default peripheral in which the operations of searching, saving, and deleting of products are effectuated.

Active Peripheral Punches / Dies
Selects the default peripheral in which the operations of searching, saving, and deleting punches and dies are effectuated.
Evidently, the tools specified in the current product must be available in the addressed peripheral, without which the software will give an error message.

ADMISSIBLE FORCE APPLIED TO THE DIES
Page: PROGRAMMING OF DIES
The maximum admissible force is defined when programming the tools. In reality, however, the admissible maximum force varies depending on the bending angle and, of course, on the other customary parameters.
The die programming page contains two pairs of fields, which make it possible to adapt the safety parameters.
The fifth field enables the user to test the result.
When only the first Ton/m field is programmed, this means that the pressure limit is constant and not depending on the angle.
The Test field indicates the maximum admissible force for the programmed angle.
When the fields open angle \ and Ton/m on the same line have been programmed, the calculation of the admissible force is limited according to the diagram shown below.

DEFINITIONS PAGE 13
If there is no specific indication given by the manufacturer, you enter the maximum admissible force already known and an open angle of 90 as below.
When the 4 fields have been programmed, the calculation of the admissible force is limited according to the diagram below.
The choice between the above method and the method explained in this paragraph depends on the known data and the decision of the person who enters the die data.

GENERAL REMARKS
The sheet metals used in the workshops hardly ever have their nominal thickness. The real thickness commonly varies from the nominal value. Also, the variation is not constant across the whole length of the sheet. The thickness on the left side can be different from the thickness on the right side of sheets with a trapezoidal section. The software allows for the correction of this type of error by dissociating the correction of one extremity from that of the other extremity of the bend.
The bending depth calculations as well as those for elongation, pressure, and crowning are based on the nominal thickness, which is programmed in the THICKNESS field.

In this Angle corrections chapter, we will deal with 3 types of correction:

Direct corrections

Angular corrections

Corrections by measuring the sheet thickness

Depending on the field in which it is entered, a correction can act on:

The relevant bend uniquely

All the bends with the same angle situated on the same section and the same profile

All the bends with the same angle of the product, also on distinct sections

DIRECT CORRECTIONS
To use direct corrections, the DNC must be in programming or semi-automatic mode, and you simply enter a value into the required field on the first table of the page. The number of the current bend is located at the top of the screen.
If the correction concerns both sides of the beam, the same value for Y1 and Y2 must be entered. It is also possible to correct the other axes, the PP, the bending force, and the crowning according to the same principles.

BEND FORCE +. _ +. _ +. _ + 212.ØØ
BENDING FORCE +._ Tons +. Tons +. Tons
CROWNING + +_ +_ 5

Direct corrections are additive. This means that if there is a global correction for the product and a correction for a given bend is programmed, the final correction for this bend will be the sum of the two corrections.

ANGULAR CORRECTIONS
After making a bend, the operator measures the angle obtained. The measured angular value is entered into the ANGLE field. The DNC automatically calculates the correction to obtain the angle originally programmed. If after making the corrected bend, the angle is still not correct, simply enter the new measured angle value. In certain cases, this operation may have to be repeated 2 or 3 times.
Attention, you must not intervene in the direct corrections table simultaneously with the angular corrections.
As for the direct corrections, the corrections can be attributed to:

BEND: Corrects only the current bend.

SECTION: Corrects all the angles of the specified section which have the same programmed value and the same tools.

PRODUCT: Corrects all the angles of the product which have the same programmed value and the same tools.

MEASURED BEND SECTION 1 PRODUCT AIM/CALIBER
ANGLE 0 90 ØØ0
LEFT THICKNESS _
RIGHT THICKNESS +

THICKNESS MEASUREMENT CENTRAL/ MANUAL/ OLD MEASURE

The DNC must be in programming or semi-automatic mode.
Program the THICKNESS MEASUREMENT field in the following manner:
THICKNESS MEASUREMENT CENTRAL NONE MODE OLD MEASURE
Measure the angle obtained.
Enter the measured value into the ANGLE field under one of the columns BEND, SECTION, or PRODUCT.
Test the result and redo if necessary.
See also the machine parameter COMPENSATION ELASTIC RETURN on the MATERIAL page. This parameter allows for a permanent correction of an angle in a given plane.

Correction by thickness measurement can be realized in several ways, but the principle remains identical. A system or the operator furnishes the DNC with the real measurement of the material. With these parameters, the DNC calculates the necessary correction.

DEFINITIONS PAGE 17
The two main methods are:

Measuring at the TDC (Top Dead Center)

Measuring at the PP (Pinch Point)

Measuring at the TDC
The principle is that the measurement is made and entered into the DNC while the machine is at the TDC.
The measurement is entered either conventionally using the keyboard, or by an RS232 link using an adequate instrument of measurement, or otherwise by a system integrated at the stop. See the Annexes for more information on this subject.

Measuring at the PP
In this case, the measurement is made at the PP. Three possibilities are offered:

Measurement by the beam.

Measurement by the beam with die displacement. See the Annexes.

Measurement of the real PP by an external system.

As for the direct and angular corrections, it is possible to affect the correction to the current bend, to the section, or to the whole product.
Also, with the correction based on the measurement of the thickness, it is possible to differentiate the correction for each extremity of the bend. The choice is made using the round robin list CENTRAL or EXTREMITIES. See further on in this chapter for the use of this possibility.

Remarks:
For technical reasons, you can only pass to programming mode during working DNC in automatic mode and programming if NO THICKNESS MEASUREMENT has been selected.
For technical reasons, the fields POS. SHEET and THICKNESS MEASUREMENT can no longer be modified in semi-automatic mode.

Measuring at the TDC

As described in the introduction to this chapter, the measurement is made when the beam is at the TDC.
Only the introduction of the measurement by the operator, such as the standard DNC software will allow, will be described in this paragraph.
The DNC must be in programming or semi-automatic mode.
Proceed in the following way:
Program the THICKNESS MEASUREMENT field in the following way:
THICKNESS MEASUREMENT CENTRAL TDC MANUAL MODE BY BEND

MEASURED BEND SECTION 1 PRODUCT AIM/CALIBER
THICKNESS MEASUREMENT CENTRAL MODE OLD MEASURE

Measure the thickness very precisely using a micrometer.
Enter the measured value into the LEFT THICKNESS field of the PRODUCT, SECTION, or BEND column depending on your needs.
By only programming the LEFT THICKNESS field, the software assumes that the measurement is central.
Leave the field.

If the introduction is made in the PRODUCT column:

The measurement made by the operator on whatever bend will remain valid until the next measurement.

The real thickness obtained is saved in association with the product.

It is considered that the real thickness is the same for all the bends.

At each new measurement, all the bends are re-corrected.

If no measurement is made, the correction is made according to the last measurement saved.

If the introduction is made in the SECTION column:

The measurement made by the operator on whatever bend of the section will remain valid until the next measurement.

The real thickness obtained is saved in association with the section to which the bend belongs. It is valid for all the successive bends belonging to the same section.

If a new measurement is made, all the bends of the relevant section are re-corrected.

If no measurement is made, the correction is made according to a possible former measurement saved in association with that section.

Remark:
This means that if any values are present in the SECTION column, they will be taken into account, and the values in the PRODUCT column will be ignored. If there are no values in the SECTION column, the values in the PRODUCT column, if they exist, will be taken into account.

If the introduction is made in the BEND column:

The measurement made by the operator on whatever bend is only valid for that bend. It will also be memorized.

If no measurement is made, the correction is made according to a possible old measure memorized in association with that bend.

Remark:
If any values are present in the BEND column, they will be taken into account, and the values in the SECTION and PRODUCT columns will be ignored. If there are no values in the BEND column, the values in the SECTION column, if they exist, will be taken into account. If only the PRODUCT column contains any values, then it is these that will be taken into account.

DEFINITIONS PAGE 19
Measuring at the PP

Only the measurement at the PP with the beam will be described in this chapter.
Principle:
The beam makes its usual approach in semi-auto or automatic mode. When it reaches just before the theoretical PP, the DNC reduces the system pressure and lands freely on the sheet. The DNC detects the stopping of the beam and in this way allows the measurement of the sheet thickness.

It is evident that in this phase, the sheet must not flex under the influence of the beam; otherwise, the measurement will be falsified. The way in which this option functions will depend directly on the machine hydraulics, the speed when arriving on the sheet, and the minimum force of the beam in this measurement phase.

It is obviously unthinkable that in this phase, the beam is out of true, as the measurement would then be totally false.
Ideally, the product should be in the center of the machine, have a bending length greater than 2/3 of the total length of the machine, and be able to support the weight of the beam without flexing.

As for the other corrections, the measurement can be made by product, section, or bend, central or at the extremities, depending on the choice made.
Before each use, a calibration must be done in order to gauge the whole.

Calibration
A calibration cycle is very similar to a measurement cycle.
Simply, the real thickness obtained is subtracted from the nominal thickness.
This difference is memorized to be used later as a correction for the real thickness calculations.

The provided document excerpts from a 2D reference manual describe various functions related to the calibration, measurement, and bending operations in a machine, possibly a press brake or similar sheet metal processing equipment. Here is a summary of the key concepts presented:

1. Calibration and Measurement Modes:

MODE BY PRODUCT, BY SECTION, or BY BEND: The user must select the appropriate mode based on the type of operation being carried out.

OLD MEASUREMENT: In this mode, no new measurements are taken. Instead, the system uses previously saved measurements, which is efficient when working with batches of similar products. This allows the system to avoid redundant measuring, saving time.

Thickness Correction: The system allows for setting maximum tolerances for material thickness, as well as defining correction factors based on thickness variations.

2. Thickness Measurement:

At the PP (Pinch Point): This measurement involves detecting the material thickness at the pinch point of the bending process.

At Extremities: It involves measuring the material thickness at both ends of the sheet being processed, which is particularly useful for products with significant thickness variation.

3. Correction Sensitivity:

The SENSITIVITY BDC field controls the depth variation required to change the bending angle by 1 degree in the current sequence. If this value is too small, it may be necessary to use a die with a wider V-opening.

4. Auxiliary Functions and Backgauge Retraction:

The BACKGAUGE RETRACTION function automatically disengages the back gauge during bending, which may be necessary in certain situations. This can also be manually adjusted by the operator.

Negative Retraction: Programming a negative retraction value allows the back gauge to move toward the die.

5. Bending Sequence and Force Calculation:

The system can automatically calculate and adjust the bending force based on material length, thickness, and tool data.

The Bend Counter tracks the number of bends made since a specific date, providing useful maintenance and operational data.

6. Bending Order:

Automatic Bending Order: The system can automatically suggest a bending order based on predefined simulation criteria.

If the automatic system cannot determine an optimal bending order, the UNBEND MODE allows the operator to manually adjust the sequence by starting from the last bend and working backward.

The system provides options to simulate and adjust the bending sequence, ensuring no collisions occur during the operation.

7. Unbend Mode:

This mode allows the operator to manually modify the bending sequence if the software cannot automatically determine a collision-free order. The system highlights potential issues, such as collisions, allowing for manual corrections and solutions to be applied.

8. Error Handling and Collision Detection:

The software checks for collisions in the bending sequence. If a collision is detected, the operator can resolve it by adjusting the sequence in Unbend Mode.

9. Programmatic Adjustments:

In case a bending sequence is incorrect or needs modification, operators can adjust settings in various fields (like FACE, STOP, etc.) to correct the sequence or modify the bending order.

This manual offers detailed guidance on managing bending sequences, adjusting machine parameters, and utilizing measurements to ensure precise operations, particularly in environments where material properties and tool configurations can vary.

The text from the 2D Reference Manual provided explains several advanced functions for controlling a press brake or similar CNC (Computer Numerical Control) machine. Here's a breakdown of the key features and terms mentioned:

1. Bending Speed Control

Bending Speed: You can reduce the bending speed using programmable settings within the machine. This helps in managing the bending process more precisely, particularly for delicate materials or special bends.

2. Backgauge or Stop Selection

Backgauge or Stop: The manual describes selecting an appropriate stop for the current sequence. The machine will recalculate the target positions of the X and R axes based on the stop chosen.

Stop Configuration: A round robin list is provided to select the stop needed for the bending sequence. If only one stop is defined in the machine, this field won't appear.

3. Bend by Bottoming Mode

Bending by Bottoming: In this mode, the machine doesn't aim for a predefined position but rather continues descending until the machine physically stops. The beam detects when it can no longer move, signaling the end of the bend.

Safety Considerations: This mode requires caution as it applies the full programmed force on the material and the tools. Operators should ensure the sheet and tools can handle this force without damage.

Execution: After passing the pinch point, the DNC (Direct Numerical Control) system monitors the beam's descent and activates the ascent cycle when it detects that the beam has stopped.

4. Material Correction Table

Material Table: This table allows operators to apply material-specific corrections to the unbent length and other parameters.

Pre-programmed Material Types: Common materials like Steel, Aluminium, and SS are included, with predefined correction tables.

Springback Compensation: Adjusts angles to account for material springback, which happens when the material does not retain the bend angle after being released.

Thickness Correction: A correction table is used for measuring thickness at the Pinch Point (PP) to ensure the correct force is applied based on the material's thickness.

5. Crowning Option

Crowning: This function compensates for deflection of the machine's beam by adjusting the force applied at various points along the length of the material.

Automatic Calculation: The crowning adjustment is calculated automatically during simulation based on applied force and calibration curves.

Manual Adjustment: Operators can modify crowning values for specific sequences, but these will be recalculated in the next simulation.

6. Data Backup and Transfer

Data Backup: It’s recommended to back up important machine settings, parameters, tools, and product configurations to avoid data loss, especially after machine installation or technician intervention.

Data Transfer: Allows transferring data to and from various peripherals (e.g., disks, network storage).

Source and Destination: You can select where the data is coming from (e.g., punch or die information) and where it's being transferred (e.g., machine parameters or production data).

Global and Partial Transfers: You can transfer all data or specific items such as product lists, machine parameters, or tool information.

7. Change Date and Time

Date and Hour Setup: You can modify the machine's system date and time via the WELCOME page, ensuring the system's time is accurate for scheduling and logging purposes.

Date/Time Format: The manual provides information on how to set the date and time format, including separators and the structure of date and time entries.

Year 2000 Compliance: The system handles dates with two digits by assuming that 00-68 corresponds to 2000-2068 and 82-99 corresponds to 1982-1999.

It looks like you've pasted a series of pages from a machine's 2D reference manual, potentially from a CNC (Computer Numerical Control) or bending machine. The manual covers various topics related to the setup and programming of tools, such as punch and die programming, collision detection, clearance settings, and ideal curve creation.

Here’s a brief breakdown of some key sections:

Punch Correction:

The "X CORRECTION" field allows users to correct a punch that may be misaligned (decentered).

It adjusts the backgauge and the origin, considering the punch’s mounting direction.

Tool Bend:

The system generates an error message if it detects a material collision at the bottom of the die or between the punch and the die.

The collision test can be turned on or off for individual bends or globally for all bends in a product.

Erase/Delete Operations:

Various erasing operations are available, such as erasing bends, sections, or entire products.

This also includes the option to delete specific punches, dies, or products.

Memory Operations:

You can erase different types of memory based on the peripheral selected (e.g., product list, tools, punches).

The free memory available is also displayed.

Gauge Clearance:

Different types of clearance can be set (e.g., maximum, outside clearance zone, or no clearance).

These settings depend on machine parameters and tool width.

Ideal Curve (CR):

Allows programming bends that create a large internal radius, with options to define the number of bends to achieve the curve.

The software automatically calculates the ideal number of bends if you input a value of 99 in the CR field.

Product and Bend Programming:

Instructions on programming the product number, segment length, internal radius, and other bending parameters for ideal curve creation.

Also includes details for adjusting the bending order and using UNBEND mode for semi-automatic bending procedures.

Some Things to Note:

Collision Detection: The system ensures that no collisions occur between the punch, die, and material during bending. This is crucial for avoiding damage.

Memory Management: Operators have control over memory management, such as deleting products or erasing bends.

Bending Parameters: You can define specific bending settings like clearance, ideal curves, and bending order, and the system will adjust the process accordingly.

It looks like you've provided a detailed section of a manual for a CNC or bending machine, discussing various settings, configurations, and simulations related to bending operations, tool corrections, and product management. Below is a breakdown and explanation of key elements in the document:

1. Tool Bend Reference Correction

Purpose: The field allows for correcting the reference of the tool pair.

Impact:

This correction affects various critical points, such as the safety point, pinch point, and bottom dead center.

The correction is saved with the product and not with the tools themselves.

Caution: Errors in this field can result in malfunctioning of the machine, material damage, or even create dangerous conditions. It is advised to apply this correction carefully.

Pinch Point:

Before Correction: There is a pinch point before making any reference correction.

After Correction: The pinch point location is modified, and it affects all switch points and the bottom dead center.

The diagram shows how adjusting the tool pair reference changes these critical points.

2. Screen Capture Feature (PC 1200 Software)

Purpose: The software allows you to capture images/screens of the interface for documentation or other uses.

How to Capture Screens:

Start up your word processor or desired software.

In the PC 1200 software, press a combination of keys (such as Ctrl + PrtSc).

The image will be transferred to the Windows clipboard.

Paste the image into your word processor or other software using the Paste function.

Special Features:

Grey Level Conversion: You can use software tools to convert color captures into grey levels (e.g., Corel Capture or freeware like Hardcopy).

Black/White Mode: To make screen captures more suitable for printing or creating documents, the software can be switched to black and white mode.

Printing Screens:

Before printing, ensure that the PC 1200 software is set to black/white to optimize screen captures for printing.

You can select printers from the Windows Printer Menu or choose the SYSTEM PRINT SCREEN option.

If you're using the "Print Screen" function, ensure that the relevant software (e.g., DOS) is configured to capture graphical images.

Printing Parameters:

software will automatically print each page, including sub-pages.

3. Product Search Criteria (Page 72)

This page allows you to search for stored products in the selected peripheral.

Search Criteria can include:

Memorization Date: Search based on when a product was saved.

Product Number: Enter product number to search for specific items.

Material Thickness, Drawing Code, Bending Length, Tool, Unfolded Length.

Multiple criteria can be combined to narrow down the search.

Wildcard Usage:

You can use wildcards in the search fields if the complete code number is not known:

represents any single character.

represents any sequence of characters.

4. Product Definition & Bending Parameters (Pages 73-75)

Product Number Page:

The Product Number defines the bending profile and sections.

Products can have multiple sections that define the profile for each part of the product.

Material Properties:

Material Strength: The material used for the product (e.g., steel, stainless steel, aluminum) has its strength in K/mm² (e.g., "Steel AC37-2 K 38.22 K/mm²").

5. Bend Simulation Criteria (Page 75)

Simulation Criteria:

Before starting the bending process, you can define criteria that the system will take into account when calculating the bending order.

Main Criteria:

These are mandatory criteria that the software must respect, like specific section length errors and precision between faces.

Secondary Criteria:

These are preference-based criteria that the software will try to accommodate but can be compromised if necessary.

Key Simulation Criteria:

Max Number of Bends: Limits the number of bends that can occur between the backgauge and the bend.

Min Length Against Operator/Total Length: Ensures a minimum length remains on the operator's side of the machine.

Minimum Number of Swings: Tries to minimize the number of swings required to perform the bend.

Minimum Number of Returns: Aims to minimize the number of returns needed during the process.

Minimum Number of Flipovers: Minimizes the number of times the sheet needs to be flipped.

Optimum Manipulation of Sheet: Ensures the best handling of the sheet based on its thickness and bend length.

Section Error on Face: Ensures section errors are located on the specified face.

Flexibility: The software allows for some flexibility, accepting small collisions with the machine during bending if configured to do so.

Summary and Key Points:

Tool Bend Reference: Correcting the reference of the tool pair affects crucial operational points, such as pinch points, and must be done with caution to avoid damage or hazards.

Screen Capture and Printing: Useful tools for creating documentation and printing machine parameters or screens. You can adjust settings for black-and-white printing and use wildcards in search queries for flexibility.

Product Management: Criteria for product searches and bending profiles help to optimize workflow, while simulation criteria allow for refining the bending process for efficiency and safety.

It looks like you're working with a 2D reference manual, likely for a numerical control (NC) machine, and it includes technical details on programming, operations, and tests related to bending and other machining functions.

Here's a breakdown of some key topics that are covered in the document:

Key Concepts from the Document:

Flexibility in Bending:

The document describes how flexibility settings can be adjusted (e.g., a flexibility of 20 allowing penetration of 40mm into a punch). It also suggests using a flexibility setting of 100 to visualize bending order in complex parts, which can then be adjusted to acceptable values.

Stops Against Slope Segments:

By default, the machine does not allow stops on slopes. However, enabling the option to allow stops on angles greater than 90 degrees can help manage more complex situations.

Switch Point (SP):

The switch point (SP) refers to the distance in millimeters from the pinch point where the beam transitions from approach speed to bending speed. This allows for more control over the machine's operation, especially when a slower, more controlled approach is needed.

Special Bends:

The manual describes different types of bends such as Normal, Preliminary, Final, Unbended, Closed, and Fictitious. Each bend type serves a specific purpose in the manufacturing process, especially for products that require special handling.

Preliminary bends are used to prepare the material for final bends, and Final bends finish the product after preliminary ones.

Program Sequence Adjustments:

The sequence for bending can be manually adjusted. For example, if a preliminary bend is forgotten or misplaced, the program can be adjusted to insert it without restarting the whole process.

U-shaped profiles might require preliminary bends that must be undone during the final stage.

Machine Functions & Controls:

The manual touches on different machine functions, including auxiliary functions and axis movements that can be programmed to start in automatic or external modes. The external mode requires the operator's direct input to trigger the start of the functions.

Top Dead Centre (TDC):

The TDC is a point in the machine's cycle, marking the distance from the pinch point to where the beam stops during its ascent. The TDC can be adjusted according to machine parameters or left to be automatically calculated.

Testing & Diagnostics:

The document explains several tests for the numerical control system, including screen tests, keyboard tests, and communication tests. It also discusses the procedure for testing the RS232 ports and troubleshooting communication errors.

RS232 Communication Test:

There's a detailed procedure for testing the RS232 ports, ensuring cables are properly connected, and verifying communication between devices like numeric controls or PCs.

Potential Actions/Functions in the Software:

Simulation of Bends: The software offers functionality to simulate bends, which can be useful for testing and fine-tuning your machine's bending process.

Inserting Bend Sequences: If a bend sequence is missing or needs to be adjusted, the system allows inserting or modifying it without starting from scratch.

Test Functions: Several system tests are available to ensure the equipment is functioning as expected, including hardware tests like the alphanumeric keyboard or the RS232 port.

Recommendations for Users:

Flexibility Adjustment: It's a good idea to experiment with different flexibility settings to ensure you can visualize and program your bending sequence appropriately, especially for complex parts.

Preliminary and Final Bends: Make sure to carefully sequence bends, especially in cases where preliminary bends are required before a final bend (e.g., U-shaped profiles).

Machine Calibration: Ensure that top dead center (TDC) and other critical parameters like switch points are properly configured for accurate machine behavior.

Bending Operations (changing bending order, forced bends)

Tool and Die Management (choice of tools, dies)

Memory Management (deleting products, bends, or sections)

User Interface Functions (cursor navigation, selecting fields, confirming actions with clicks)

Safety and System Messages (warnings, error messages like "Non-feasible simulation")

Function:
Switches 1 view display to 4 view display and vice-versa.
The 4 view display allows selecting rapidly the one, which seems the most appropriate for continuing the work.

Procedure:
Click on the pictograph.
4 views appear on the screen.
Click right on the window, which most closely resembles the view you wish to examine.
4 new views are displayed.

Each right-click on the selected window displays 4 new views.
Usually, after 3 to 5 clicks, the required view appears.
Click left on the window you wish to see in full screen and the system switches to 1 view mode.

BEND: ADDED
PRODUCT 3D / MODIFY 1W and MODIFY 2W page
Function:
Allows adding a bend between two segments of the outline.

Procedure:
Click on the 1st segment; it becomes violet.
Click on the 2nd segment; it becomes violet A and the 1st segment selected B becomes green.
Enter the values in the dimensioning window.

The sum of the segments A and C are equivalent to their construction segment.
The sum of the segments B and D are equivalent to their construction segment.

In this example, the left segment of the triangle has been selected first, followed by the right segment. The bend is automatically placed in the middle of the two segments.

The bend has been placed elsewhere by modifying the data in the dimensioning table.

ERASER
PRODUCT 3D / MODIFY 1W and MODIFY 2W page
Function:
Allows deleting a vertex or a bend.

DELETING a vertex or a bend
It should be understood by deleting a vertex that the junction between two segments of the outline is deleted and replaced by a single segment.

Click on the pictograph.
Position the cursor on the vertex or bend to be deleted.
Click.

Remark:
If deleting a vertex brings a bend to the edge of the outline, the message THE BEND FIRST appears in the interactive field.
The relevant bend must first be deleted.

Depending on the operations realized, it is possible that two co-linear segments appear to be only one when one is in the extension of the other or if they overlap.
The sketch on the left below demonstrates this situation.

FORCED BENDS
PRODUCT 3D / MODIFY 1W and MODIFY 2W page
Function:
Allows defining the forced bends.
Forced bends are those bends which can be realized in one bending operation. Because of this, they must necessarily in the flattened-out product be on a bending line collinear.

Procedure:
Click on this pictograph.
Click on the 1st bend.
Click on the 2nd bend, etc.
Each bend selected as forced is displayed in red.
To leave and validate, click on a spot away from the relevant zone.

If the cut is not placed at the required spot, click on ABANDON in the dimensioning window and start again (see Abandon).

Enter the values in the dimensioning window.
A and B are used to adjust the starting position of the peduncle on the construction segment.

The segment on which the cut has been inserted has been automatically divided into two segments A and B whose sum is equivalent to the former segment.
C is the distance between the construction segment and the hole. The segment C is called the peduncle.
D and E define the size of the hole.
F is the angle between the segment C and the hole.
G is the angle between the segment C and the segment B.

The peduncle is an element of internal construction.
Physically, it is composed of two adjacent segments separated by mm connecting the construction segment to the internal cut.

Remark: The internal cut is placed in the face on which the construction segment is located.

LEG
Bend 3D page
Allows selecting another leg than the one displayed in the current sequence.
The software automatically positions the axes and the stop fingers separated at 80° or another value defined by the machine parameters onto the new leg segment.
It immediately displays the new sheet metal position.

Procedure:
Click on this pictograph.
Click on the required leg; the stop positions itself on the new leg.
The LEG field is modified with the number of the new leg.
If the segment chosen is not valid or if the cursor is badly placed, the POSITION BADLY DEFINED message is displayed.
Attention not to leave the graphical window, otherwise the pictograph is deactivated.

Remark:
This function allows easily and effectively choosing the new legs.
A leg defined automatically by the simulation or by the method described above is called a nominal leg.

Allows defining the station to be used to realize a given bend if the choice exists.

Procedure:
Click on this pictograph, a window opens.
Click on the drawing of the punch to be used.
The sheet metal positions itself under the new punch.
Click on LEAVE or outside the working window to validate the data and close the window.

Options of sheet metal positioning
Positioning under a punch
It may be necessary to position the sheet metal, instead of centered, aligned to the left or the right of the punch.

By clicking repeatedly on the punch, the product positions itself:
in the centre, left edge, right edge, centre, left edge, etc.

Click on the LEAVE field of the window to validate the position or pass to the next bend.

Forced bends under 2 punches
In the case where 2 forced bends must be realized under 2 distinct station punches, there is a way which allows positioning automatically the sheet metal between these 2 punches.

If you click between the 2 punches, the software positions the space between the 2 forced bends centrally in relation to the space between the 2 punches.

To select the space between the 2 punches, it may be necessary to modify the 3D view in order to see the whole face.

It seems like you've shared an excerpt from a technical manual, likely related to a 3D CAD or manufacturing tool for designing and modifying products. This manual covers various functions such as bending, modifying, rotating, and adjusting different segments or faces of a 3D model.

To break it down, here's an overview of some key features from the document:

1. Forced Bends and Click-Based Adjustments

In the example, there are forced bends (a, b, c, d) that need to be bent in specific stations. The manual mentions adjusting the spaces between forced bends (x, y, z) using a click-based system. This helps in positioning the bends efficiently.

2. Modifying Faces

The manual details how to modify faces on a 3D model by attaching rectangular or trapezoidal faces and adjusting their dimensions (height, base, angles, etc.).

You can also adjust whether a bend is present or not by toggling a symbol in the dimensioning window.

3. Rotation and Visualization

It talks about rotating the 3D model around a horizontal axis or multiple axes (like 3 axes), allowing users to view the design from different angles and positions.

There's a specific pictograph for switching between wireframe mode (for easier manipulation) and hidden face mode (for detailed viewing of the product).

4. Stop Positioning

The section on stop positioning helps fine-tune the position of specific stops around a bending machine or tool. Users can adjust positions numerically or by clicking directly on the graphical product.

5. Zooming

Users can zoom into specific parts of the 3D model by selecting a window. This functionality is helpful when dealing with smaller or detailed parts of the design.

6. Tools and Punch Positioning

In the Tools and Punch positioning section, the manual explains how to set the position of tools (like punches) in the tool holder. It also allows users to define positions for sheet metal based on tool placement.

7. Vertex and Trapezium Additions

There’s functionality to add a vertex to the outline to divide segments, as well as the ability to add trapezoidal faces to the outline. The dimensions and angles can be adjusted for these shapes to fit within the design specifications.

This section of the manual is about setting up and simulating a 3D product design, focusing on steps such as positioning tools, defining product data, simulating bends, and working with different segments of the design. Below is a detailed breakdown of key concepts covered in this portion of the manual:

1. Positioning the Tools:

To define the tool positions, first, click on the die grip to display a die with a size equivalent to the maximum press size.

Then, introduce the left tool position using the cursor on bI, and define the tool length using the cursor on L.

If products and tools are already defined on the PRODUCT NUM page, these tools will appear on the TOOLS POSITION page. However, their positions will be arbitrary, and you will need to adjust them according to your needs.

2. Product Data Setup:

Product Data Field: The manual suggests clicking on the PRODUCT DATA field to begin inputting product information such as material thickness, sigma, punch, and die data.

To introduce the product data, you can use lists for material and punch/die types, or you can type them in directly.

3. Creating Segments:

A segment is a straight part of the outline that joins two vertices. Its length is defined when entering the data.

Segments can be:

Split into two parts (using the Vertex pictograph).

Modified or lengthened (using the Stretch pictograph).

Used as a support for the construction of other elements like rectangles, trapeziums, or internal cuts.

The current segment is highlighted in violet, with a circle indicating the origin of the segment or the current vertex. You can move between segments using the arrow keys or by clicking on the relevant segment.

Superimposed Segments: If multiple segments are superimposed, they cannot be selected using the mouse directly. You must use the PgDn or PgUp keys to switch between them. To delete or modify superimposed segments, follow specific steps outlined in the pictographs.

4. Simulations:

The manual describes simulation as a software task that searches for an optimal sequence of bends based on predefined criteria. Users can manually modify the proposed bending order if needed.

Simulation of Bends:

Complete Simulation: This option redoes the entire simulation, disregarding any previous bend solutions. It's useful if you're looking for new solutions by modifying the simulation criteria.

Simulation with Programmed Bends: If you’ve already defined certain bends manually, you can let the software find the solution for the remaining bends, without modifying the order of the programmed ones.

Simulation of the Bend: After setting the bending order, the software shows the product position before bending. To view the final result after bending, you can press the function key F5 to simulate the bend.

5. Creating the Base Element:

The base rectangle is an essential part of the product's outline and can be defined by entering dimensions for A and B. After entering these values, you can continue constructing the product using the pictographs for different elements.

6. Stretching and Lengthening:

The Stretch pictograph allows you to modify the product by stretching or lengthening certain parts, which can be helpful when adjusting the design after initial creation.

7. Vertex:

A vertex is the starting or ending point of an outline segment. It is fundamental for defining the shape and geometry of the product's outline.

8. Pictographs & Functions:

Pictographs play a crucial role in guiding the user to perform specific operations, such as selecting a tool, creating a bend, or deleting an element.

Zoom: The Zoom pictograph helps in zooming into specific areas of the design to better manipulate or inspect the details.

Summary of Key Operations:

Tool Positioning: Set and adjust tool positions for die and punch elements.

Product Data Setup: Input material and other essential product information.

Segment Creation: Define straight-line segments, which can be split, stretched, or modified.

Superimposed Segments: Use the PgUp/PgDn keys to navigate and modify overlapping segments.

Simulation: Test different bending sequences and adjust criteria to optimize the product.

Base Element: Define the starting rectangle for the product.

Vertex Management: Create and manage vertices to form the shape of the product.

Stretching/Lengthening: Modify the length or dimensions of product segments.
