8.3.12 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.
Blank
For plunge turning, 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.
