8.5.11 Plunge turning (CYCLE952)
Function
Using the "Plunge turning" function, you can machine any shape of groove.
Contrary to grooving, the plunge turning function removes material on the sides after the
groove has been machined in order to reduce machining time. Contrary to stock removal, the
plunge turning function allows you to machine contours that the tool must enter vertically.
You will need a special tool for plunge turning. Before you program the "Plunge turning"
cycle, you must define the contour.
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.
