3.6. Breakpoint Restoration Process
3.6.1.Breakpoint restoration
1)
In case of manual pause or power outage in machining operation, the system will automatically save the
current position of cutting torch as a breakpoint, which will be kept permanently in the system, whether
power the system off or not.
2)
In automatic mode, press [F2] key to select RESBREK function and then [START] key to start breakpoint
restoration as long as there is no change with the current program.
3)
If the position of cutting torch does not change, the system will prompt "Breakpoint" when a breakpoint is
found and wait for subsequent command. User may select piercing directly or position adjustment of
cutting torch. Refer to 3.4 for details.
4)
If the position of cutting torch does change and is off from the breakpoint, the system will provide three
options when a program breakpoint is found, which is virtually
position adjustment of cutting torch
.
ORI PATH RET:
To return to the breakpoint at speed G00, which is often used for the breakpoint set for cutting torch
replacement;
CUT RET:
little bit off from the breakpoint after breakpoint restoration, whic is somewhat like piercing along the exterior
margin, making the breakpoint more smooth;
HOLE HERE:
the same operation as previous, which can also be used for transitional cutting.
Now, it is allowed to press a 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.
If press
[ESC]
key when a breakpoint is found, the system will exit machining mode.
3.6.2Attention:
Never try to change the machining program, rotation angle and scaling proportion whether it is
breakpoint restoration or power-off restoration, which will be automatically saved by the system and
free from affect by power-off operation; otherwise, the system can not find the breakpoint.
3.7. SECTION(section selection)
3.7.1. Start SECTION function
SECTION: to assign system to start up machining operation from any section or piercing point.
Press [F1] to select SECTION function and the system will show a menu as shown in the figure below:
