Siemens Sinumerik 840D sl Programming Manual page 379

Description
Without groove wall offset (transformation type 512):
The control 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.
With groove wall offset (transformation type 513):
Kinematics as above, but an additional longitudinal axis parallel to the peripheral direction
The linear axes are positioned perpendicular to one another.
The velocity control makes allowance for the limits defined for the rotations.
