1.1 The TNC 320
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 320 is designed for milling and
drilling machine tools with up to 4 axes (optionally 5 axes). Instead of
the fourth or fifth axis, 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
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.
You can also enter and test one program while the control is running
another.
Compatibility
The feature content of the TNC 320 is not the same as that of the TNC
4xx series and iTNC 530 controls. Part programs created on the
HEIDENHAIN controls TNC 150 B and later can only run on the TNC
320 under a condition. If NC blocks contain invalid elements, the TNC
will mark them during download as ERROR blocks.
