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 an easy-to-use conversational
programming language. They are designed for milling, drilling and
boring machines, as well as machining centers, with up to 18 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.
Programming: In HEIDENHAIN conversational and
DIN/ISO
The HEIDENHAIN conversational programming format 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
FK free contour programming feature performs 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.
Compatibility
Machining programs created on HEIDENHAIN contouring controls
(starting from the TNC 150 B) may not always run on the TNC 640.
If NC blocks contain invalid elements, the TNC will mark them 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,
