B-63324EN-1/03 OPERATION 4.AUTOMATIC OPERATION
- 145 -
- Restart of automatic operation with the block return switch turned on
If the cycle start button is pressed while the block return switch is on,
the tool length compensation value and the cutter compensation value
are recalculated, and automatic operation is restarted toward the
compensated end point from the current position.
Fig. 4.9 (c)
The tool moves toward the recalculated end point from its current
position regardless of whether it has been returned to the start point of
or an arbitrary point in the interrupted block prior to pushing the cycle
start button.
CAUTION
The tool may cut the workpiece when it is being moved
toward the end point of the interrupted block. In this
case, an alarm is displayed and the tool is inhibited
from moving to the end point. This function is referred
to as the block restart interference check.
If the tool will cut the workpiece when automatic
operation is restarted, press the <CAN> key to reset
the alarm. Move the tool to an appropriate position
while observing the movement of the tool. Then,
perform the block restart operation again from step 1
of procedure 3.
The tool is retracted to this
position so the tool can be
replaced.
