The suffixes E and F indicate the export versions of the TNC The export versions of the TNC have the following limitations:
Linear movement is possible in no more than 4 axes simultaneously.
The machine tool builder adapts the useable features of the TNC to his machine by setting machine parameters. Some of the functions described in this manual may not be among the features provided by your machine tool.
TNC functions that may not be available on your machine include:
Probing function for the 3-D touch probe
Digitizing option
Tool measurement with the TT 130
Rigid tapping
Returning to the contour after an interruption
Please contact your machine tool builder to become familiar with the features of your machine.
Many machine manufacturers, as well as HEIDENHAIN, offer programming courses for the TNCs. We recommend these courses as an effective way of improving your programming skill and sharing information and ideas with other TNC users.
Touch Probe Cycles User's Manual:
All of the touch probe functions are described in a separate manual. Please contact HEIDENHAIN if you require a copy of this User's Manual. ID number: 329 203-xx.

Introduction
1.1 The TNC 410, the TNC 426 and the TNC 430
1.1The TNC 410, the TNC 426 and the TNC 430
HEIDENHAIN TNC controls are workshop-oriented contouring controls that enable you to program conventional machining operations right at the machine in an easy-to-use conversational programming language. They are designed for milling, drilling and boring machines, as well as for machining centers. The TNC 410 can control up to 4 axes, the TNC 426 up to 5 axes, and the TNC 430 up to 9 axes. You can also change the angular position of the spindle under program control.
An integrated hard disk provides storage for as many programs as you like, even if they were created off-line or by digitizing. For quick calculations you can call up the on-screen pocket calculator at any time.
Keyboard and screen layout are clearly arranged in such a way that the functions are fast and easy to use.
Programming: HEIDENHAIN conversational and ISO formats
HEIDENHAIN conversational programming is an especially easy method of writing programs. Interactive graphics illustrate the individual machining steps for programming the contour. If a production drawing is not dimensioned for NC, the HEIDENHAIN FK free contour programming does the necessary calculations automatically. Workpiece machining can be graphically simulated either during or before actual machining. It is also possible to program in ISO format or DNC mode.
You can also enter and test one program while the control is running another. With the TNC 426, TNC 430 it is also possible to test one program while another is being run.
Compatibility
The TNC can execute all part programs that were written on HEIDENHAIN controls TNC 150 B and later.

1.2Visual Display Unit and Keyboard
Visual display unit
The TNC is available with either a color CRT screen (BC 120) or a TFT flat panel display (BF 120). The figure at top right shows the keys and controls on the BC 120, and the figure at center right shows those of the BF 120.
1Header
When the TNC is on, the selected operating modes are shown in the screen header: the machining mode at the left and the programming mode at right. The currently active mode is displayed in the larger box, where the dialog prompts and TNC messages also appear (unless the TNC is showing only graphics).
2Soft keys
In the footer the TNC indicates additional functions in a soft-key row. You can select these functions by pressing the keys immediately below them. The lines immediately above the softkey row indicate the number of soft-key rows that can be called with the black arrow keys to the right and left. The line representing the active soft-key row is highlighted.

The BC 120 is sensitive to magnetic and electromagnetic noise, which can distort the position and geometry of the picture. Alternating fields can cause the picture to shift periodically or to become distorted.
Screen layout
You select the screen layout yourself: In the Programming and Editing mode of operation, for example, you can have the TNC show program blocks in the left window while the right window displays programming graphics (only TNC 410). The available screen windows depend on the selected operating mode.
To change the screen layout:
Press the SPLIT SCREEN key: The soft-key row shows the available layout options (see “Modes of Operation,” page 6).
Select the desired screen layout.
