Reference point under automatic machining
Reference point is initial point of machining program（set by G92）.One program run once
（include free play）, Reference point will be saved automatically（Also set by parameter）.
Once reference point is set, orientation of reference point is very easy, as follows:
1）Please aim the knifepoint to special position of steel plate that waiting for cut（know
coordinate）, set the current coordinate.
2）Under automatic or manual mode, if select return reference point function, system will
automatically return to reference point.
Startup under automatic machining
After all prepare work is ok, there are two means to startup the automatic machining program.
1.Press【Startup】.
2.Press outside“startup”button.（refer chapter 6.1 “outside input interface”）
Control and error compensate under automatic machining
After automatic machining beginning, only these keys are effect:
1．【Pause】: Press this , system will decrease speed till stop. Execute instruction M according to
the set of G61 to keep the current display contents. If press【Startup】, system will keep on running.
Under pause state, if find deviation of dimension, you can press【F2】key to enter into manual state
（in inch state automatically, increment is 0.01mm），Operator press direction key to adjust the
position of knifepoint, its move be considered compensation. Adjustment finished, press【Startup】
system will neglect compensation movement and keep on running according to before adjustment.
If press 【Quit】, system will return to main picture.
Error compensation under pause state is reference point’s compensation in fact.
2．【F↑】,【F↓】Moving axis adjust speed key: Increase or decrease speed magnification, change
1% once.

3．【Pgup/S↑】,【Pgdn/S↓】Control cutting gun rising or falling ,Press key, cutting gun rising
or falling, loose it will stop.
4．【Stop】：
：：
：Outside button（refer chapter 6.1 “outside input interface”），Signal can derive
from input port. All stop when this key is effect.
Return and renew machining according to original track
During machining, because of cutting incompletely, need return and renew machining, You
can deal with as follow:
1．Press【Pause】, system will decrease speed till stop and display＂pause＂sign. Prompt
（Graphics mode）＂Ｆ２manual Ｆ６return＂，Press【F2】can enter into manual compensation
function（refer below），press【F6】can enter into return and renew machining function.
If select【F6】, System will hint:
Return＜－
＜－＜－
＜－ －＞
－＞－＞
－＞forward
Indication: Press【←】, System will return along original trace. Press【→】, System will forward
along original trace base of return. During return, if reach position that want to return, You can
press【Pause】again, repeat the above-mentioned procedure, select again keep on returning or
forward.
２．You may press【Pause】again when system get to the return position，After system stop
Steady, you can press the strong current key correspondingly（like Preheat perforation, open
cutting oxygen etc.），Press【→】again, and select machining forward.
３．Above-mentioned operate can run repeatedly till get the satisfactory effect.
Break recover and power cut disposal
When system pause by man-made, it will save automatically the current working trace
(cutting tip’s position) as a break. This break will be saved forever, regardless power off. Power on
again or enter into automatic mode, if only the current program is not changed you can press【G】
key to resume break. When find the break, system will hint ＂pause＂state, You can press the
strong current function key correspondingly (such as preheat perforation, open cutting oxygen
etc.), Press【Startup】again, system will keep on running from break’s position.

17
After machining pause, if you want to quit automatic state and enter into manual state to
move cutting tip(whatever how much)，When press【G】key to begin resuming break, system will
move the cutting tip to the position of break firstly, then resume break. Of course, if you changed
the current coordinates by hand, the break will not be resumed normally.
If during machining, you encounter failure of electricity, you can enter into
automatic mode firstly after get back electric power. Press【F3】key will set the current
coordinate as break and recover like above-mentioned. Attention: This moment you must not move
the cutting tip or set the current coordinate.
Only pause operation can generate break.
2.4 Manual function
Under main picture, press【F2】enter into manual mode, display:
Display under manual function
Like automatic mode，but have any distinction:
1． Under left of the menu display the current increment value.
2． Under right hint：Press【G】, you can modify the inch increment.
3．Press【X】, you can modify the X value. Press【Y】, you can modify the Y value.

8.Press【F6】key，system enters into test-position function. Test-position is testing the precision
distance from the current position of cutting tip to the origin of machine tool. Concrete usage:
Firstly, You should aim the cutting tip to a special point（such as reference point），test the
current coordinate and modified（press“X/Y”），Press【F6】key, cutting tip begin to return to
origin of machine tool and save it as machine’s origin of parameter. Return-position is same to
test-position from shape, but their results are not same: Return-position is that send the origin
value of machine tool to current coordinates , but test-position is that send the current
coordinate to origin of machine tool.
9.Press【F↑】and【F↓】,you can adjust the manual magnification. Note: Manual and automatic
