8.6 RETRY PROCESSING FUNCTION
Overview
A burning condition may occur during laser machining, disabling
further machining. In such a case, a normal operation may be able to
be resumed by returning the nozzle to a point where it was before the
burning condition occurred and by retrying processing. This is done
using the retry processing function. This function operates as follows:
When a machining failure is detected, the nozzle moves back along
the machining path to a specified point with the beam turned off.
When it gets to the specified point, it enters a machining state and
goes forward along the same machining path toward the point where it
started going backward (retrace start point). When it gets to the retrace
start point, the nozzle resumes machining as directed by the program.
This function cannot be used with the three-dimensional machining
function. Because the retry processing function is based on the
FS16-M retrace function, it is necessary to specify the retrace function
and conform to the retrace function specification.
Operation
The retry processing function operates as follows:
[1] Sets the retry processing mode signal (RVSLSR) to "1", and
resets the automatic operation stop signal (*SP) to "0" according
to the machining failure detection signal during program
execution. After that, specifies as follows:
- Movement = discontinued
- Beam = off
- Assist gas = off
- Tracing control = off (*1)
