With cylinder surface curve transformation with groove
side compensation, the axis used for the compensation
should be set to zero (y = 0), in order that machining of
the groove is aligned with the programmed groove
center line. Cylinder surface curve transformation
Rotary axis
The rotary axis cannot be programmed because it is
assigned to a geometry axis and cannot therefore be
programmed directly as a channel axis.
Axis use
The following axes cannot be used as positioning
axes or reciprocating axes:
• The geometry axis in the circumferential direction
of the cylinder surface curve (Y axis)
• The additional linear axis used in groove side
compensation (Z axis)
