Rotate

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.

You can use the "Stock removal" cycle for longitudinal or transverse stock removal of

corners at outer or inner contours.

Removing stock from corners

For this cycle, the safety clearance is additionally limited using setting data. The lower value

is taken for machining.

Please refer to the machine manufacturer's specifications.

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.
