Step 10.
Change the spindle speed for finishing
(master axis at 2000 rpm and polygon syn-
chronization axis at 4000 rpm with a phase
difference of 0).
[Repeat steps 4, 5, and 6.]
.
Step 11.
Polygonal turning (finishing 1)
[Repeat step 7.]
.
Step 12.
Change the phase by 180 degrees.
[Repeat steps 4, 5, and 6.]
.
.
Step 13.
Polygonal turning (finishing 2)
G50. 2 ;
.
.
.
Step 14.
Release the polygon synchronization mode.
The polygon synchronization axis (second
spindle as tool rotation axis) stops. The
first spindle rotates at a speed specified by
an S command.
M05;

.
Step 15.
The first spindle stops (end).
For polygonal turning with two spindles, the following information is
displayed on the diagnosis display screen.
