Chapter 10 Code Explanation
Y – rotate angle, can be set from -360° to 360°.
I – image of X axis, make image along X axis, 1 expresses that there is image, 0
expresses that there is no image.
J –image of Y axis, make image along Y axis, 1 expresses that there is image, 0
expresses that there is no image.
Note:
A code can have G99, also cannot. If there is G99, the parameter X, Y, I, J after code
should not be ignored. Mirror image and rotation will take the origin (0, 0) of Descartes
coordinate as reference point.
10. Program notice items
The program must contain the instruction of G92 (reference point setting) and
M02(end of program).
G41/G42 must match with G40 to be used. If G41/G42 is ignored, the default kerf
compensation is zero; if G40 is ignored, kerf compensation is available.
If G20 / G21 is ignored, the system will execute G21 (metric unit).
If G90 / G91 is ignored, the system will execute G91 (relative coordinate).
M07 and M08 can’t be neglected.
When there is one parameter in the code of G00、G01、G02、G03 is ignored, if this
parameter is absolute coordinate, the system will set it G code coordinate value of last
row; If it’s relative coordinate, the system will set it 0.
G00、G01、G02、G03 can be simplified: G0、G1、G2、G3.
If there is contiguous G00 (or G01、G02、G03) around, the following G00 (or G01、
G02、G03) can be ignored.
