5.2.12.5 SPINDLE INDEXING PROCEDURE
Before using the spindle indexing function, it is
important to consolidate the hardware resource, and
to control the 1/O signals by the sequencer.
The following is a general operation procedure.
For details, refer to the instruction manual of the
machine tool manufacturer.
(1) Command the M code specified by the machine
tool manufacturer the position in the part program
to perform the spindle indexing.
(2) Execute the part program. The spindle
indexing completes by executing the spindle
indexing M code.
(3) Then continue to execute the part program.
Note :
Spindle indexing cannot be performed under the
solid tap mode. Command spindle indexing after
canceling the solid tap mode.
