Siemens SINUMERIK 828D Programming Manual page 369

With groove wall offset (transformation type 513):
Kinematics as above, but an additional longitudinal axis parallel to the peripheral direction
The linear axes are positioned perpendicular to one another.
The velocity control makes allowance for the limits defined for the rotations.
Groove traversing-section
In the case of axis configuration 1, longitudinal grooves along the rotary axis are subject to
parallel limits only if the groove width corresponds exactly to the tool radius.
Grooves in parallel to the periphery (transverse grooves) are not parallel at the beginning
and end.
