Face milling (3D-milling A4, B4, C4, A5, B5, C5)

Function
Face milling is used to machine curved surfaces of any kind.
For this type of 3D milling, you require line-by-line definition of 3D paths on the workpiece
surface.
The tool shape and dimensions are taken into account in the calculations, which are
normally performed in CAM. The fully calculated NC blocks are then read into the control via
postprocessors.
