In all turning cycles apart from contour turning (CYCLE95), in the combined roughing and
finishing mode, when finishing it is possible to reduce the feedrate as a percentage.
Please also refer to the machine manufacturer's specifications.
Stock removal (CYCLE951)
Function
You can use the "Stock removal" cycle for longitudinal or transverse stock removal of
corners at outer or inner contours.
Note
Removing stock from corners
For this cycle, the safety clearance is additionally limited using setting data

Please refer to the machine manufacturer's specifications.
● Roughing
In roughing applications, paraxial cuts are machined to the finishing allowance that has
been programmed. If no finishing allowance has been programmed, the workpiece is
roughed down to the final contour.
During roughing, the cycle reduces the programmed infeed depth D if necessary so that it
is possible for cuts of an equal size to be made. For example, if the overall infeed depth is
10 and you have specified an infeed depth of 3, this would result in cuts of 3, 3, 3 and 1.
The cycle would reduce the infeed depth to 2.5 to create 4 equally sized cuts.
The angle between the contour and the tool cutting edge determines whether the tool
rounds the contour at the end of each cut by the infeed depth D, in order to remove
residual corners, or is raised immediately. The angle beyond which rounding is performed
is stored in a machine data element.
