Programming technological functions (cycles)
10.5 Contour turning - Milling/turning machine
Blank
When grooving, 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.
Requirement
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 blank contour and the second call is the
finished-part contour (see also Section "Programming (Page 574)").
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.
For additional information, please refer to the following documentation:
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.
Example of the limit in longitudinal external machining

Permitted limit: Limit line XA is outside the contour of the blank
