Machine description
● Over the circumference of a drum A (front-plane machining), the machine has distributed:
– 4 main spindles, HS1 to HS4
– 4 cross slides
– Each slide has two axes.
– Optionally, a powered tool S1-S4 can operate on each slide.
● Over the circumference of a drum B (back-plane machining), the machine has distributed:
– 4 counterspindles GS1 to GS4
– 4 cross slides
– Each slide has two axes.
– Optionally, a powered tool S5-S8 can operate on each slide.
– Each counterspindle can be moved through a linear axis, for example, for transferring
● Couplings:
– If drum A rotates, all of the main spindles of this drums are subordinated to a different
– If drum B rotates, all of the counterspindles and all of the transfer axes of this drum are
– The rotations of drums A and B are autonomous.
– The rotations of drums A and B are limited to 270 degrees.

NCU assignment
The axes and spindles of a position (for this example) are each assigned to an NCU. One of
the NCUs, the master NCU, also controls the axes for rotating drums A and B. The result is 4
NCUs with a maximum of the following axes:
