CNC System Instruction
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 con-
tinue to process from the breakpoint location if [PIERCE] key is pressed after preheating.
2) CUT RET(cut return)
After piercing, the cutting torch returns from the current position to the adjustment beginning point along a straight line at cutting speed and
continue machining along the original path without stop, which is somewhat like extended pierced, making the piercing point more
smooth.
；
3) HOLE HERE(piercing here)
After piercing, set the coordinates at current point as coordinates of "adjustment beginning point", and continue machining along the origi-
nal path to fulfill transitional piercing function.
4) Attention:
Be sure to have the system preheated sufficiently(for flame cutting) before taking steps 2) and 3) , for piercing operation will start
right away once the operation is selected.
It is recommended to preheat the system(for flame cutting) and then press [START] key to select appropriate operation.
3.6. Original Path Return
When it is necessary to return the cutting torch along the original path due to failure to cut through in machining oper-
ation, handle it in the following ways:
3.6.1Return along original path
Press [PAUSE] key to suspend the running system. A "pause" mark will appear on the system display in addition to
prompt as shown in the figure below.
Press [F6] key to return the cutting torch along the original path .
Press [F7] key to advance along the original path after returning. In the process of return, if the cutting torch fails to
reach the required position, press [PAUSE] key again and repeat the above procedure until it reaches the right posi-
tion.
3.6.2 Return at G00(when reach a piercing point)
In the process of return, the cutting torch will stop at G00 or a piercing point for operator to select going on return or
advancing.
3.6.3 Operation after returned
After the cutting torch returns to the designated position, it is allowed to select position adjustment of cutting torch
(refer to 3.4) or piercing directly by pressing the appropriate heavy
-
current function key such as PREHEA(piercing
preheat) and CUT(cutting oxygen).
It is common practice to
--
Press [PIERCE] key after preheating operation is done, or
For flame cutting operation, press CUT key(open the cutting oxygen) if the cutting torch lifts or continue ma-
chining if the cutting torch lowers; or
For plasma cutting operation, ignite arc and do not go on machining until the arc ignition is completed.
