With groove wall offset (transformation type 513)
Kinematics as above, but an additional longitudinal axis parallels 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.
With additional linear axis and groove wall offset (transformation type 514)
On a machine with a second linear axis, this transformation variant makes use of redundancy in order to perform improved
tool compensation. The following conditions then
apply to the second linear axis:
● A smaller working area
● The second linear axis should not be used for traversing the part program.
Certain machine data settings are assumed for the part program and the assignment of the corresponding axes in the BCS
or MCS.
