Figure 12-5 Machining grooves on a cylinder surface with X-Y-Z-C kinematics
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.
