In the program, S speed, N program segment number, T tool number, X.U represent X axis coordinate instruction, Z.W represent Z axis coordinate instruction, and also represent tool withdrawal, B is tool axis, C is spindle, G and M are program instructions, and R radius also represents tool withdrawal and I center in some instructions, and there are still many things to learn by yourself. Some letters have different meanings in different places in the program.

General g code interpretation

G00: Positioning or Fast Moving

G0 1: linear interpolation

G02: Circular interpolation/spiral interpolation clockwise

G03: Circular interpolation/spiral interpolation counterclockwise

G04: residence time or delay time

For example: G04 X 1000 (or G04 X 1.0)

G04 P 1000 means stay 1 sec.

G09: Stop the inspection accurately or precisely (check whether it is within the target range)

G 10: programmable data input

G 17: select XPYP plane XP: X axis or its parallel axis.

G 18: select the y axis of YP:ZPXP plane or its parallel axis.

G 19: select the plane ZP:Z of YPZP: Z axis or its parallel axis.

G20: inch input

G20 1: mm input

G28: Return to the reference point for testing.

Format: G9 1/(G90) G28 X__ Y__ Z__

Return the reference point through the intermediate point X__ Y__ Z__ (absolute value/incremental value instruction)

G29: Return from Reference Point

G9 1/(G90) G29 X__ Y__ Z__

An instruction (absolute value/incremental value instruction) to return the target point X__ Y__ Z__ from the starting point through the reference point.

G30 returns to the second, third and fourth reference points.

g 9 1/(G90)G30 P2 X _ _ Y _ _ Z _ _； Return to the second reference point (P2 can be omitted. )

g 9 1/(G90)G30 P3 X _ _ Y _ _ Z _ _； Return to the third reference point

g 9 1/(G90)G30 P4 X _ _ Y _ _ Z _ _； Return to the fourth reference point

X__ Y__ Z__: Through the midpoint position (absolute value/incremental value instruction)
