Plunge-Turning (Cycle952) - Siemens SINUMERIK 828D Operating Manual

9.3.12

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.
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 390)").
Note
Execution from external media
If you execute programs from an external drive (e.g. local drive or network drive) then you
require the execution from external storage function (EES).

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.
