Preparatory Functions for Machining
3.1 Approach reference points
Approach reference points
The axes will need to be referenced depending on how the turning
machine is configured and the requirements of the application. For this
purpose, the axes are traversed to a certain position that the control
system recognizes. After the axes have been referenced, the control
knows the position of the machine working point.
Any previously set reference points are re-approached when the
control is switched on again.
