In this example, assume that M61 clamps the workpiece and sets signal
G1138#1 SYNC2 to “1” and that M62 resets signal G1138#1 SYNC2 to
“0” and unclamps the workpiece.
NOTE
It is necessary to make the speed of spindle S1 equal that
of spindle S2. For example, issue spindle commands of
path 1 to both S1 and S2.

Machining is performed
using turret 1 (X1--axis)
and spindle S2 (Z2 --axis).
Interpolation for the X1-- and Z2--axes can be carried out by either of the
following two methods.
