Programming of full-surface machining
When programming a contour on the rear face, be sure to consider
the orientation of the XK axis (or X axis) and rotational direction of
arcs.
Insofar as you use drilling and milling cycles, there are no special
aspects to rear-face machining, since these cycles refer to predefined
contours.
For rear-face machining with the basic commands G100 to G103 the
same conditions apply as for rear-face contours.
Turning operations: The expert programs for reclamping contain
converting and mirroring functions.
The following principle applies for rear-face machining (2nd setup):
+ direction: Goes away from the workpiece
– direction: Goes toward the workpiece
G2 and G12: Circular arc clockwise
G3 and G13: Circular arc counterclockwise
Working without expert programs: If you do not use the converting
and mirroring functions, the following principle applies:
+ direction: Goes away from the main spindle
– direction: Goes toward the main spindle
G2 and G12: Circular arc clockwise
G3 and G13: Circular arc counterclockwise
