Required machine kinematics
The two linear axes (XM, ZM) must be mutually perpendicular. The rotary axis (CM) must travel parallel to the linear axis ZM
(rotating around ZM). The linear axis XM intersects the rotary axis CM (center of rotation).

Extended machine kinematics
The YM linear axis is also available to enable the machine kinematics requirements to be met (see above). This is arranged
perpendicular to XM and ZM respectively and, with these, forms a right-handed Cartesian coordinate system.
This type of kinematics is typical for milling machines and makes it possible to machine grooves where the groove wall and
groove base are mutually perpendicular – provided the milling tool diameter is less than the groove width (groove wall offset).
These grooves can otherwise only be machined using milling tool diameters which fit precisely.
