12.6 Coordinate transformation 6FC5 150-0AD04-0AA0
Coordinate transformation TRANSMIT (implemented from software version 1 onwards) is used
for face milling of turned parts (lathes). In order to implement this, a C axis and a powered
milling cutter are required in addition to the X and Z axes.
2D/3D coordinate transformation (implemented from software version 2) is required when
surfaces are configured on a plane (2D coordinate transformation) or in space (3D coordinate
transformation) in such a way that they can only be machined by the (real) axes by including
rotations (the tool being positioned as normal on the plane to be machined).
