Plunge-turning (CYCLE952)

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.

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.

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 351)").

Positive value: Compensation allowance is kept

Negative value: Compensation allowance is removed in addition to finishing
