Description
Without groove wall offset (transformation type 512)
The controller transforms the programmed traversing movements of the cylinder coordinate system to the traversing

movements of the real machine axes:

●

Rotary axis

●

Infeed axis perpendicular to rotary axis

●

Longitudinal axis parallel to rotary axis

The linear axes are positioned perpendicular to one another. The infeed axis cuts the rotary axis.
