Use parameter DIAG2 to enter the final depth that you wish to reach with the cut-off. With
pipes, for example, you do not need to cut-off until you reach the center; cutting off slightly
more than the wall thickness of the pipe is sufficient.
Sequence
1. The tool first moves to the starting point calculated internally in the cycle at rapid traverse.
2. The chamfer or radius is machined at the machining feedrate.
3. Cut-off down to depth DIAG1 is performed at the machining feedrate.
4. Cut-off is continued down to depth DIAG2 at reduced feedrate FF2 and reduced spindle
5. The tool moves back to the safety distance at rapid traverse.

The easiest way to part off a component is to use CYCLE92.
The cycle can be found and parameterised from the "Turn." softkey.
