SD55587 $SCS_TURN_CONT_MIN_REST_MAT_AX1 Limit value during contour turning for
removal of residual material in the di‐
rection of axis 1 (for G18 Z).
This also applies to residual machining
– stock removal, grooving and plunge
turning.
50 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.
Example: If the SD is set to 50% and the final machining allowance is 0.5 mm, any residual material 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.
SD55588 $SCS_TURN_CONT_MIN_REST_MAT_AX2 Limit value during contour turning for
removal of residual material in the di‐
rection of axis 2 (for G18 X).
This also applies to residual machining
– stock removal, grooving and plunge
turning.
50 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.
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.
