There are two types of cylinder surface coordinate
transformation:
•
without groove side compensation
•
with groove side compensation
Without groove side compensation:
The control transforms the programmed traversing
movements of the cylinder coordinate system into
the traversing movements of the real machine axes:
– Rotary axis
– Infeed axis perpendicular to the rotary axis
– Longitudinal axis parallel to the rotary axis
The linear axes are positioned perpendicular to each
other. The infeed axis intersects the rotary axis.

With groove side compensation:
Same kinematics as above, plus:
– Longitudinal axis parallel to the direction of the
circumference
The linear axes are positioned perpendicular to each
other.
The speed control provides defined limits for the
rotary movements.
