Details

Function

The workpiece axis and the skiving tool axis must be related to each other in a defined angle (α).

 

The offset of the cutting tool (Y) caused by rotating to the defined angle (α) must be compensated with the Y-axis of the machine.

 

 

Synchronization of work piece and tool rotation.

Feed movement in Z-axis.

When skiving is finished the cutter has to move towards X.

Please consider:

At the end of the gear/spline there must be sufficient clearance for the cutter.
