11.CONTROL FUNCTIONS B-63662EN/01
- 84 -
<3> When retracting is completed, the machine retraces the specified
distance, then stops. After confirming the retrace completed
signal and turning off the retrace signal, triggering automatic
operation causes the nozzle to approach the surface of the
workpiece.
<4> After the nozzle approaches the workpiece surface, the assist gas
is turned on.
<5> A move command that will end at the retrace start point is
generated automatically, the laser beam is turned on, and the
machine starts moving forward again. When it reaches the
retrace start point, a block that was executed at <1> is called to
resume programmed operation.
<6> After restart, it is checked whether the restart completion
distance has been passed through.
<7> If no machining error is detected during movement through the
restart completion distance, machining is continued.
<8> If a machining error is detected before the restart completion
distance is passed through, steps <2> to <4> are retried.
<9> If retry is repeated a specified number of times, it is assumed that
machining restart is impossible, and skip operation is carried out.
<10>The machine begins positioning at the end of the block executed
at step <1>. When it gets to the end of the block, it stops there in
single block stop mode.
<11>After confirming that the skip completed signal is on and turning
off the retrace signal, triggering automatic operation causes the
nozzle to approach the workpiece.
<12>After the nozzle approaches the workpiece surface, the assist gas
is turned on, and piercing is carried out under the machining
condition used most recently. When piercing is completed, the
cutting assist gas is selected.
<13>The laser beam is turned on, and the next block begins
execution.

This function is valid only for X-Y facing. It cannot
be used with functions for cylindrical machining,
normal direction control, three-dimensional
machining, etc.
