This is a simple machine tool with a vertical spindle and a table that can move in two dimensions. The modeling always starts with the Linear Z axis that is aligned with the primary spindle. The X axis is defined as the longest axis perpendicular to the Z axis. The spindle is now defined as a Rotary C axis that rotates around the Z axis.

Three Axis Mill

The right hand rule applies when naming the axes and defining positive motion and rotation. In this case the Rotary axis only operates as a spindle, so it will have a constant valued DataItem called RotaryMode. This machine is only capable of executing a single program and therefore only capable of a single path. The following XML describes a simple configuration for this machine.
