Superimposed Interpolation
Composite lathes sometimes add a slave axis to the master axis.
In these cases, the system may, for example, use CNC to generate functions for each axis and superimpose
those results for operation.
Multi-axis superimposed control determines the travel distances in mm/rev in relation to the master axes.
Then, the reference values of the axes are calculated and operation is performed according to the travel dis-
tances of the master axes.
The relevant axis can be controlled during the communications cycle by adding or subtracting the movement
of the controlled master axis to the calculated travel distance.
