Grooving (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.
Precondition
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.
If CYCLE62 is present twice, then the first call is the unmachined part contour and the
second call is the finished-part contour (also see Chapter "Programming (Page 418)").
Set machining area limits
If, for example, you want to machine a certain area of the contour with a different tool, you
can set machining area limits so that machining only takes place in the area of the contour
you have selected.
Feedrate interruption
To prevent the occurrence of excessively long chips during machining, you can program a
feedrate interruption.
