CNC System Instruction
3.8. SECTION(section selection)
3.8.1. 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:
Move the cursor with
[↑]
or
[↓]
key and make one choice from two machining options.
According to your option, the system will prompt to input the serial number of the option (program line number or the serial number of
piercing point).
3.8.2. Two cases for SECTION machining option:
3.7.2.1Transitional machining: to start machining somewhere different from the start position of the program;
3.7.2.2 Repeat the machining operation starting from a certain section of the program.
For the former case, a scrap work piece is often used for aiming at the piercing point and machining directly(
HERE POSITION
option);
For the latter case, the reference point is used for positioning(
REF POSITION
option).
For these two options, the system will prompt an option menu as shown below after start
-
up:
If "
HERE POSITION
" option is selected, the system will draw the full pattern first and then draw a large cross cursor at the piercing
point. Operator may press [S] key to zoom in the pattern and observe if it is the expected piercing position. If not satisfied, operator
may press [ESC] to exit the machining mode and take the option again.
If it is the expected piercing point, use heavy
-
current control switch for ignition and preheat before press [PIERCE]
key to start operation.
If "
REF POSITION
" option(Reference Point Positioning) is selected, operator should aim the cutting torch at the
reference point. After started up, the system will control the cutting torch to reach the piercing point and then
perform the operations as above.
3.9. MOVE HOLE for Thick Plate
In automatic mode,
MOVE HOLE
option is taken for thick plate.
For edge piercing method, it is important to
move the cutting torch to the nearest edge of steel plate before piercing
operation.
Preheat the system and press
[START
] key at the end of preheat. The cutting torch will cut the steel plate along a straight
line to the piercing point at selected cutting speed and then go on machining.
