Plunge-cutting (CYCLE952)

Function
The "Grooving" function is used to machine grooves of any shape.
Before you program the groove, you must define the groove contour.
If a groove is wider than the active tool, it is machined in several cuts. The tool is moved by a
maximum of 80% of the tool width for each groove.
Blank
When grooving, the cycle takes into account a blank that can consist of a cylinder, an allowance
on the finished-part contour or any other blank contour.
Requirement
For a G code program, at least one CYCLE62 is required before CYCLE952.
If CYCLE62 is only present once, then this involves the finished part contour.
