This functionality supplements the existing turning functions and permits the face and lateral surface machining of cylindrical workpieces on lathes and milling machines with revolving base. The workpiece is moved by the rotary axis or spindle (C axis) and the driven tool (e.g. a milling cutter) by the two translatory axes X (or Y) and Z. Specific ettings are required in the parameters P-CHAN-00008, P-AXIS-00015 and P-AXIS-00018 for C axis machining.

Example of a configuration of a C axis in the axis parameters

kenngr.achs_mode    0x0204  #MODULO and CAX

Facing and lateral surface machining can be described in Cartesian coordinates.

All interpolation types (such as linear, circular or spline interpolation) are supported on the end face and lateral surface. The functionality also permits the machining of path contours running through the turning centre point. The C axis is automatically aligned on lathes.

The 2.5D tool radius compensation can be used with the familiar G commands.

The use of extended dynamic monitoring can specifically prevent dynamic axis characteristics from being exceeded with the C axis function and also with contours running close to the turning centre point.

The main axes for all machining modes are X, Y (depending on machine type), Z and C.
