Transformations
6.8 Kinematic transformation
Cylinder surface transformation with groove wall correction
The controller transforms the programmed traversing movements of the cylinder coordinate
system to the traversing movements of the machine axes:
● Rotary axis (Y / CM)
● Infeed axis vertical to the axis of rotation (XM)
● Supplementary axis for groove wall correction vertical to the X-Z plane (YM)
● Longitudinal axis parallel to the axis of rotation (ZM)
The linear axes are positioned perpendicular to one another.
