Description
Withdraw complete blank:
● Yes
● No
Feed - withdraw for blank "yes"
Cutting-off cycle in the following block
● Yes
● No
Rear
- for main spindle in counter-spindle
Work offset in which the coordinate system, which was shifted according to ZW
and by ZV as well as mirrored in Z, must be saved:
● Basic reference
● G54
● G55
● G56
● G57
● ...
● Yes
The Z value of the work offset can be directly written to the input screen form.
● No
The actual Z value of the work offset is used.
● Offset Z = 0 (abs)
● Workpiece zero is offset in Z direction (inc, the sign is also evaluated)
The workpiece is re-clamped when switching between the main spindle and
counterspindle. The new work offset defines the position for machining at the
machine. However, the simulation must know by which amount the work
offset has shifted with respect to the workpiece, so that both sides of the
machining can be displayed.
Machining position for special axis (abs.); machine coordinate system
