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.
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 442)").
Note
Execution from external media
If you execute programs from an external drive (e.g. local drive or network drive), you require
the "Execution from external storage (EES)" function.

SINUMERIK Operate Commissioning Manual
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.
The limit lines must not intersect the contour on the side facing the machining.
This limit has the same effect during roughing and finishing.
