Transformations
6.8 Kinematic transformation
TRACYL transformation types
There are three forms of cylinder surface coordinate transformation:
●
●
●
For cylinder peripheral curve transformation with groove side compensation, the axis used
for compensation should be positioned at zero (y=0), so that the groove centric to the
programmed groove center line is finished.
Axis utilization
The following axes cannot be used as a positioning axis or a reciprocating axis:
● The geometry axis in the peripheral direction of the cylinder peripheral surface (Y axis)
● The additional linear axis for groove side compensation (Z axis).

Rotary axis
The rotary axis cannot be programmed as it is occupied by a geometry axis and thus cannot
be programmed directly as channel axis.
