Cycle group Soft key Page
Cycles for pecking, reaming, boring and counterboring 72
Cycles for tapping, thread cutting and thread milling 102
Cycles for milling pockets, studs and slots 138
Cycles for producing point patterns, such as circular or linear hole patterns 168
SL (Subcontour List) cycles which allow the contour-parallel machining of relatively
complex contours consisting of several overlapping subcontours, cylinder surface
interpolation 208
Cycles for multipass milling of flat or twisted surfaces 236
Coordinate transformation cycles which enable datum shift, rotation, mirror image,
enlarging and reducing for various contours 258
Special cycles such as dwell time, program call, oriented spindle stop and
tolerance 282
Cycles for turning operations 294
If required, switch to machine-specific fixed
cycles. These fixed cycles can be integrated by
your machine tool builder.
