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 scope of functions of the TNC 320 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 320. If NC blocks
contain invalid elements, the TNC will mark them during download as
ERROR blocks.
