Position Display In A Tilted System; Monitoring Of The Working Space - HEIDENHAIN TNC 640 User Manual

Cycles: Coordinate Transformations | WORKING PLANE (Cycle 19, DIN/ISO: G80, software option 1)
Automatic positioning of rotary axes
If the rotary axes are positioned automatically in Cycle 19:
The TNC can position only controlled axes
In order for the tilted axes to be positioned, you must enter a
feed rate and a set-up clearance in addition to the tilting angles,
during cycle definition.
Use only preset tools (the full tool length must be defined).
The position of the tool tip as referenced to the workpiece
surface remains nearly unchanged after tilting
The TNC performs the tilt at the last programmed feed rate.
The maximum feed rate that can be reached depends on the
complexity of the swivel head or tilting table.

Position display in a tilted system

On activation of Cycle 19, the displayed positions (ACTL and
NOML) and the datum indicated in the additional status display are
referenced to the tilted coordinate system. The positions displayed
immediately after cycle definition might not be the same as the
coordinates of the last programmed position before Cycle 19.

Monitoring of the working space

The TNC checks only those axes in the tilted coordinate system
that are moved. If necessary, the TNC outputs an error message.
