Example
The workpiece is to be machined on two sides with the axis configuration shown in the
diagram. To do this, you create two combinations of coupled axes.

Further Information
Axis types
A coupled axis grouping can consist of any desired combinations of linear and rotary axes. A
simulated axis can also be defined as a leading axis.
Coupled-motion axes
Up to two leading axes can be assigned simultaneously to a trailing axis. The assignment is
made in different combinations of coupled axes.
A coupled-motion axis can be programmed with the full range of available motion commands
(
G0, G1, G2, G3, etc.). The coupled axis not only traverses the independently defined paths, but
also those derived from its leading axes on the basis of coupling factors.
