As the tool bends during plunge turning, the tool cannot travel right up to the contour during
stock removal. The lateral distance to the last cut by which the next cut is shortened is
specified in the following channel-specific cycle setting data.

The roughing step for residual machining is not executed, if the material to be removed is
less than 50% of the finishing allowance. The material is only removed when finishing.
less than 0.25 mm is not removed with the residual machining – but is removed during finishing. If
during a machining step, less residual material is present than defined in the SD, the error
message "No material present" is issued. This means that this residual material roughing step can
be omitted because no machining is performed.
The roughing step for residual machining is not executed, if the material to be removed is
less than 50% of the finishing allowance. The material is only removed when finishing.

Limit value during contour turning for
removal of residual material in the
direction of axis 1 (for G18 Z).
This also applies to residual machining
– stock removal, grooving and plunge
turning.
Limit value during contour turning for
removal of residual material in the
direction of axis 2 (for G18 X).
This also applies to residual machining
– stock removal, grooving and plunge
turning.
