Combining the block restart function and the retraction and recovery function
The procedure for combining the tool retraction and recovery and block
restart functions is shown following. See Item II-4.9 for the block
restart function.
If the tool breaks, for example, after automatic operation is suspended,
the tool is replaced, and the offset value is changed, the operation is
resumed from the start point of or an intermediate point in the
interrupted block.
Start of automatic operation
When a problem occurs and the TOOL RETRACT switch is turned on,
the tool is retracted and the automatic operation is held. The machine
enters the tool retraction mode.
Move the tool manually and replace the tool or take an appropriate action.
Start the cycle with the block return switch turned on.
When automatic operation is resumed, the tool retraction mode is
canceled. Turn off the block return restart switch.
(1)
Change the tool offset value if necessary.
Return to the automatic mode and turn on the block return switch.
When the block return switch is on, executing the block can be resumed
by restarting it at an arbitrary position. The position may not always be
the retraction position.
Return to the automatic mode,
and return the tool to the
retraction position by turning on
the TOOL RETURN switch then
turning it off again.
Turn on block return switch and
move the tool to the start point
by continuous manual feed.The
tool automatically stops at the
start point.
