Function
The "Cutoff" cycle is used to cut off balanced parts (for example, screws, bolts, or pipes)
dynamically.
You can program a chamfer or rounding on the edge of the machined part. You can machine
at a constant cutting rate V or speed S up to a depth DIAG1, from which point the workpiece
is machined at a constant speed. As of depth DIAG2, you can also program a reduced
feedrate FF2 or a reduced speed SS2, in order to adapt the velocity to the smaller diameter.
