8.4.2. Adjustment of cutting position
8.4.2.1Situations necessary to adjust the position of cutting torch:
1)
If the cutting torch is blocked or replacement is necessary, the usual practice is to move the
cutting torch to somewhere safe and move it back to the starting point after the situation is
resolved.
2)
When it is required to pierce along the exterior margin and not position the piercing point
at the exterior edge, the usual practice is to pinpoint an appropriate position in the exterior
of workpiece for piercing and then cut the workpiece back to the starting point along a
straight line before continue normal machining without stop.
3)
In case of transitional cutting, too many workpiece or large size of workpiece, it might be
necessary to relocate the cutting torch.
8.4.2.2Situations allowed to adjust the cutting position:
(1) pause process, (2) return process,(3) piercing process, (4) section selection, (5) hole
selection and (6) breakpoint restoration
If operator intends to change the position of cutting torch in the above-mentioned states,
it is allowed to press [↑], [↓], [←] and/or [→] key to do so(in this case, it is manual
multiplying factor, adjustable). When the expected position is reached, press [Start] key,
as shown in the following dialog box:
1) ORI PATH RET(original path return)
Return the cutting torch to the adjustment beginning point at speed G00 and wait for other operation;
at this step, it is allowed to press an heavy-current function key such as IGN(ignition), PREHEA(piercing
preheat), CUT(cutting oxygen), etc.
Tip: The system will continue to process from the breakpoint
location if [PIERCE] key is pressed after preheating.
