2.1 The TNC 640
HEIDENHAIN TNC controls are workshop-oriented contouring
controls that enable you to program conventional milling and
drilling operations right at the machine in easy-to-use Klartext
conversational language. They are designed for milling, drilling
and boring machines, as well as machining centers, with up to 24
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. 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.
HEIDENHAIN Klartext and DIN/ISO
HEIDENHAIN Klartext, the dialog-guided programming language
for workshops, is an especially easy method of writing programs.
Programming graphics illustrate the individual machining steps
for programming the contour. If no NC-dimensioned drawing
is available, then the FK free contour programming will help.
Workpiece machining can be graphically simulated either during a
test run or during a program run.
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.
Compatibility
Machining programs created on HEIDENHAIN contouring controls
(starting from the TNC 150 B) may not always run on the TNC 640.
If the NC blocks contain invalid elements, the control will mark
these as ERROR blocks or with error messages when the file is
opened.
Please also note the detailed description of the
differences between the iTNC 530 and the TNC 640.

iTNC 530 compared", page 913.
