As a result, the machine operator can do his own pro- gramming, he no longer need bother with tedious G codes.
This allows the machine operator to make better use of his specialized knowledge. Together with the Touch Probe System, the TNC aids the operator at workpiece setup. TNC graphics allow him to check a program for errors before actual machining, thereby ensuring error recognition and correction.

This provides you with a constant overview by giving you all necessary information at a glance. TNC is available with interactive dialogs in 8 languages.
External programming: Our TNC is perfect for external programming. Programs may be of any length. In line with transfer blockwise, the TNC can read and simultaneously run very long programs, e.g. for 3-D machining tasks. Even if you are not yet considering external programming or CAD applications, it's good to know that the TNC is equipped for computer linkage.

The control can store up to 32 NC programs with a total of 3100 blocks. For workpiece machining, or external data input and output each NC program is assigned with an identification number of up to eight digits and the program length is indicated. You therefore have the possibility of quick access to any program. Programs can also be protected against erasing or alteration.
4th Axis 5th Axis In addition to the three linear axes X, Y, and Z, the TNC355 can control two further axes, i.e. the 4th and 5th axis. Both additional axes can be programmed for rotary movements, e.g., a rotary table, swivel head, or a universal swivel table, or for linear movements, e.g., a ram or retractable quill. The control interpolates the movements of max. 3 out of 5 axes, i.e., 3 out of 5 axes can be traversed simultaneously. With the controlled simultaneous movements of a rotary table and a linear axis, it is possible to machine spirals, threads, or helices. A controlled quill offers greater flexibility for boring operations or for workpieces which are difficult to access. The 4th and 5th axis can be activated at any time, thus permitting the subsequent retrofitting of a rotary table to the machine. On the other hand, both axes of the TNC can be utilized for display of position values only.
HEIDENHAIN TNC 355 Entering workpiece geometry Entering position data as per workpiece dimensioning Nominal position data for workpiece machining can be entered into the control in conformance with the dimensioning of the production drawing: Cartesian or polar coordinates absolute or incremental dimensions inches or millimeters.
Absolute dimensions Absolute dimensions Incremental dimensions Incremental dimensions Tool compensation saves calculation work It's the workpiece contour, i.e. the drawing dimensions, and not the path of the tool center, that you program. The control takes the respective tool radius into the program blocks are independent of the tools used for machining; tool dimensions are entered control also compensates for various tool lengths.

HEIDENHAIN TNC355 Linear interpolation Straight line milling in any direction.

Chamfers To mill a chamfer on a workpiece corner, entry of the chamfer side length is sufficient. Circular interpolation Four ways of circular programming. The control's circular interpolation function lets you produce circular studs, slots, contours and rounded corners. The circular contour may be defined in Often, the radius and endpoint of c Use this key for circles that con- the drawing by the circle center and the circular arc are known, but not nect tangentially to the preceding the endpoint of the arc. the presents no problem for contour.

No chatter marks on the machined surface To program helical interpolation, you first enter the coordinates of the center, the total angle of rotation and the height or depth of the helix. HEIDENHAIN TNC355 Canned cycles Certain frequent machining operations are pre-programmed as canned cycles, e.g. the milling of slots, rectangular and circular pockets, peck-drilling, tapping. These canned cycles reduce program- ming time and simplify program entry. Program errors are minimized.

HEIDENHAIN TNC355 Milling cycles for variable contour pockets Particularly in the field of tool, die, and mold manufacturing, not only rectangular or circular pockets, but also pockets with irregular contours are required. So far, it was necessary to calculate all the endpoints of the areas and lines for programming the contour, and each individual step for clearing out the pocket had to be entered. Pockets with any desired contour, level base, and perpendicular walls can be easily programmed. You only specify the allowance for finishing and the pocket depth. A suitable choice of roughing-out angle reduces machining time to a minimum. The control prompts you for the data, just as in the other machining cycles.
HEIDENHAIN TNC 355 Procedure Pilot drilling is possible. The cutter then plunge-cuts at the calculated positions and produces a channel around the inner contour of the pocket and the outer contour of the islands, with the specified finishing allowance. The pocket is roughed-out line-by-line in stepover milling. If need be, the contours of the pocket and the islands are finished to size.
HEIDENHAIN TNC355 Variable parameter programming When compiling a program, numerical values, nominal positions, feed rates, tool dimensions, and entry data for canned cycles can be substituted by space retainers or so-called variable parameters. With these parameters, you can then directly assign numerical values, either directly or via mathematical or logical functions. The control can interrelate parameters among themselves or with numerical values via the following mathematical functions: , and more. If a contour is programmed using these functions, the control makes real-time calculations during program run. You can use this feature to mill cams, spirals, 3D profiles, or for part families, e.g., when dimensions relate to one another.
Example: draw punch A frequently used form of the drawing punch is the cuboid with rounded program can be modified fast by using parameters from cuboid to hemisphere.
HEIDENHAIN TNC355 LOGICAL FUNCTIONS A parameter can be compared with another parameter or with a numerical value (greater, smaller, equal, unequal), e.g., the control can establish whether an actual value and a predetermined value coincide after execution of a program section. Depending on the comparison, a jump to a certain program label can be commanded.
Example: truncated cone You can use parameter programming to produce three-dimensional shapes, a truncated cone.
With the program, you can produce a copy by modifying a single parameter only. Radius of base, radius of sectional surface, starting angle, angular increment, height of truncated cone. Excerpt from parameter program. LBL20. Mirror-imaging Scaling-1i. You can mirror-image symmetrical shapes milling or drilling patterns in the machining plane. This saves programming one half of the nominal positions. The scaling factor is important and useful in manufacturing electrodes, for example, or where shrinkage factors must be taken into account. Automatic compensation for shrinkage form allowances. Datum shift and coordinate system rotation. In cases where milling and drilling patterns are repeated at shifted positions, there's no need for reprogramming. You only specify the offset. If a milling or drilling pattern is rotated on a circular arc, you program a coordinate system rotation.
Program call and subprogramming. Creating your own machining cycles. Programs can be integrated into other programs. In conjunction with variable parameter programming, this enables you to create machining cycles to your own specific needs. Program recalls can be nested up to 4. Machining of outer contour can also allocate a program and subprogram. Time-saving via subprograms and program part repeats. Repetitive machining routines do not have to be re-entered within one program. Subprograms can be labeled as subprograms and called-up, as required. Up to 254 subprograms can be programmed. Datum shift, Coordinate system rotation, Subprogram call, Correction of entry errors. Easy and convenient. You can page backward and forwards through the program. The control checks program entry and displays error messages in plain language format. This feature applies not only to plain-language format but also to programming per ISO standard.
Programming assurance through a test run without machine movement. On completion of program entry, you can run an analytical program test without machine check for logical errors. It helps the operator gain confidence in working with the control. Program check with graphics. The TNC 355's graphics feature helps you check a program on-screen by simulating the machining of the workpiece. Depending on the purpose of the check, various display modes are available. Projection in three planes, similar to a production drawing. You can shift the sectional plane wherever you wish. Plan view with depth display, optionally with 5 or 17 shades of gray, provides a clearly depicted simulation of machining progress in a three-dimensional view. The workpiece is displayed in two full or sectional elevations and in a plan view. You can change from one display mode to another at any time or generate a magnified image of a workpiece detail. See your mistakes before they happen.
Plan view with depth display 3D view In three-dimensional display, you can tilt or rotate the workpiece. The workpiece is shown in a plan view with varying grades of depth shading; the darker, the deeper. Optional 5 or 17 shades. This display mode gives an especially clear depiction of machine action. Documentation Hardcopy print-out of the on-screen image is possible via the RS-232-C/ interface. Magnify Any workpiece detail can be selected for simulation of machining in magnified applies to all graphics display modes.
Floppy disk unit for external program storage Simple and safe, long-term program Connection of other peripherals The storage Our FE401 offers an almost floppy disk and magnetic tape cassette unlimited storage facility for machining units also have RS-232-C/ interfaces for connection of further commercially available peripherals such as data printers or punched tape read/write units.
Programs from an external programming station The floppy disk control memory capacity, transfer blockwise, in data blocks, is possible with simultaneous machining.
Simple operation The floppy disk unit is operated via the keys on the TNC. You simply press the -key, and the FE immediately helps you with its dialog questions and prompts on the TNC-display screen similar to workpiece contour programming.
HEIDENHAIN TNC355 Touch probe systems with cable connection 3D Touch Probe Systems from HEIDENHAIN are suited for use both in tool and die manufacture as well as in automated production equipment. In tool and die manufacture, electronic alignment reduces machine idle time and increases accuracy of the workpiece position. In series production, the 3D Touch Probe Systems can be employed to monitor work processes, e.g., for tolerance checking during machining or also for workpiece identification prior to machining.
3D Touch Probe Systems are simple to use: the probe head is equipped with a tool shank and can be mounted in the spindle like any tool. Both during manual operation as well as in the programming of probe cycles, the TNC numerical control supports the operator with questions and prompts in plain language dialog.
Touch Probe Functions for Electronic Workpiece Alignment Calibration Basic Rotation Corner as Datum The stylus deflection resulting from contact has an effect on probe accuracy and must be calculated in the result of a measurement. The TNC control determines this compensation value simply and quickly with the probe cycles Calibration of effective radius and Calibration of effective length In subsequent probing operations, the TNC automatically accounts for these compensation values in the output of measured values.

In a workpiece surface which is programmed touch probe cycle, only four points of a bore or shaft are probed. to one of the three machining planes can be set as reference plain. With the aid of the Touch Probe, the control determines the current position value of the surface in the probe axis. The control calculates the center point, which can then serve as datum for workpiece machining.

Through comparison of this distance with given tolerance limits, deviations are quickly recognized and suitable corrective measures can be taken without interruption of machining. Improve your accuracy through early error recognition and compensation. 511 Example: Workpiece Identification Workpiece A or workpiece B with differing heights are set up for machining via pallet changer. After the change, the 3D Touch Probe System measures under program control the height of the workpiece, which is then stored in a Q parameter. By comparing parameters the V TNC control can now automatically call and execute the program appropriate to Q or Q1>o the workpiece.

Distance-Coded Reference Marks
Following a power interruption, the correlation between the position of the machine slides and the position values in the machining program is maintained by moving each axis over its reference point. The scale graduation consists of sealed linear encoders with distance-coded reference marks.
It is not always possible to approach the reference points without difficulty, for instance, due to the danger of a collision between the tool and workpiece or because of long traverses. Now, HEIDENHAIN has developed linear encoders with distance-coded reference marks, allowing for a split-second approach to the homing position.
The distance for reference point approach is a mere 20 mm.

Two Dialog Special-Oriented Customized Spindle Stop
In addition to the officially spoken language, English language dialogs are available for commissioning or training in foreign countries.
For the gripper of the tool changer to grasp the tool or for the 3D-infrared touch probe system TS 511 to be in the proper position, the spindle position must have a specific orientation. Acquisition of the actual spindle position is performed by an incremental rotary encoder ROD 428 with 10241 lines. The nominal spindle position is determined by the orientation cycle or machine parameters.
Positioning is performed via a PLC-command.
Machine parameters that affect the TNC functions and those that influence contour calculation can be declared as user parameters and made accessible to the operator.
Example: Switchover between HEIDENHAIN-dialog-programming and ISO format, stepover of milling cutter with pocket milling, switchover between the actual dialog language and basic dialog language English. Positioning within 3D.
Interrogation markers provide information as to whether the actual value for a pocket number corresponds to the nominal value. If the axes of your machine are locked via Hirth-type serration, you can enter a positioning pattern via machine parameters.
HEIDENHAIN TNC355 is equipped with an integrated PLC for a standard program, which can be used by the machine manufacturer as is or adapted to the machine characteristics.
User-defined machine parameters can be declared to influence contour calculation and TNC functions. The program memory of the PLC is insufficient. You can combine up to 300 PLC statements in direct programming at the control, eliminating the need for a separate programming unit.
