Note
The axes are given the following names in order to clarify the assignments of axes to slides
and positions:
Xij with i slide (1, 2), j position (A-D)
Zij with i slide (1, 2), j position (A-D)
Whereas the positions and their slides remain in one place, main spindles, counterspindles,
bar feed axes STN and transfer axes ZG move to new positions as the result of rotations of
drums V or H.
For example, the axes to be managed per NC when the slide is taken into account are as
follows for the configurations shown in the above diagrams:
