Description
● 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
Description
Teaching in the park position and angular offset is possible
● With main spindle
The blank is gripped with the main spindle
● With counter-spindle
The blank is gripped with the counter-spindle
Buffer work offset:
● Basic reference
● G54
● G55
● G56
● G57
● ...
● MCS
The park position is specified in the machine coordinate system. Teaching in the
park position and angular offset is only possible in the machine coordinate
system.
● WCS
The park position is specified in the workpiece coordinate system.
Park position of tool in X direction (abs)
Park position of tool in Z direction (abs)
Flush counter-spindle chuck
● Yes
● No
Direction of rotation
● Spindle rotates clockwise
● Spindle rotates counter-clockwise
● Spindle does not rotate
Spindle speed – (only when the spindle rotates)
Angular offset
Transfer position (abs.)
Position, feedrate reduction (abs or inc)
Position from which a reduced feedrate is used.
