6.14 Interactive Working Plan Generation (IWG)
Recessing radial/axial (G866)
The IWG generates the cycle G866 for the form elements “Recess
type D” (sealing ring) and “Recess type S” (guarding ring).
If an oversize has been specified, TURN PLUS first rough-machines
and then finish-machines the recess.
The dwell time is taken into account:
Only for finishing, if the oversize is defined
For each recess, if the oversize is not defined
