PREPARATION BEFORE STARTING MASS PRODUCTION F-45
1.
The chuck interlock function disables spindle start and cycle start unless the
workpiece is clamped in the chuck.
2.
The tailstock spindle interlock function, when made valid, disables cycle start unless
the tailstock spindle is in the OUT state.
12-3
Both-center-work Operation (Tailstock Specification)
Generally, for the operation without opening/closing the chuck, the operator must understand the
following interlock functions and pay sufficient care for safety.
Chuck interlock function
Disables spindle start and cycle start unless the workpiece is clamped in the chuck.
Tailstock spindle interlock function
Disables cycle start in the memory (tape) mode unless the tailstock spindle is in the OUT
state.
At the same time, the program must be written by using these interlock functions fully and with
operation safety taken into consideration.
For interlock functions, refer to page A-5 (2) (INTERLOCK FUNCTIONS THAT
<Program example>
O0001 ;
Machining program
M05 ;
M11;
(Chuck unclamp: The STATUS indicator
[CHCL]
goes off.)
M30 ;
When machining a workpiece using the program in the example above, the operator must step on
the chuck opening/closing footswitch before starting a new cycle after changing a workpiece to
turn on the STATUS indicator
[CHCL]
. Otherwise, the chuck interlock function precludes the cycle
start. If the
(ST) switch is pressed mistakenly, the machine does not start to protect the
operator.
If the center at the spindle side is clamped in the chuck, the center at the spindle side
will fall or move to cause the workpiece to fall if the program (M11) indicated above is
used. Therefore, do not use this program in such a case.
