1.1 The TNC 620
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. The TNC 620 is designed for milling and
drilling machine tools, as well as machining centers, with up to 5 axes.
You can also change the angular position of the spindle under program
control.
Keyboard and screen layout are clearly arranged in such a way that the
functions are fast and easy to use.
Programming: HEIDENHAIN conversational
format
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 (Advanced programming features software
option), performs the necessary calculations automatically. Workpiece
machining can be graphically simulated either during or before actual
machining (Advanced graphic features software option).
You can also enter and test one program while the control is running
another.
Compatibility
The scope of functions of the TNC 620 does not correspond to that of
the TNC 4xx and iTNC 530 series of controls. Therefore, machining
programs created on HEIDENHAIN contouring controls (starting from
the TNC 150 B) may not always run on the TNC 620. If NC blocks
contain invalid elements, the TNC will mark them as ERROR blocks
during download.
