The CNC lathe programming code generally has the following:

G00 and G01

There are two kinds of G00 motion trajectories: straight line and polyline. This command is only used for point positioning and cannot be used for cutting.

G01 moves to the target point specified by the command by the linear motion method according to the specified feedrate, and is generally used for cutting.

G02 and G03

G02: Clockwise circular interpolation G03: Counterclockwise circular interpolation

G04 (delay or pause command)

Generally used for positive rotary switching, machining blind holes, stepped holes, turning and grooving

G17, G18, G19 plane selection command, specified plane machining, generally used in milling machines and machining centers

G17: X-Y plane, which can be omitted or a plane parallel to the X-Y plane

G18: X-Z plane or plane parallel to it, only X-Z plane in CNC lathe, no special designation

G19: Y-Z plane or plane parallel thereto

G27, G28, G29 reference point command

G27: Return to the reference point to view and confirm the reference point orientation.

G28: Actively return to the reference point (through the center point)

G29: Come back from the reference point and use it with G28

G40, G41, G42 radius compensation

G40: Undo tool radius compensation

Give it so much, pack it at night and give it again.

G43, G44, G49 length compensation

G43: Positive length compensation G44: Length negative compensation G49: Undo tool length compensation

G32, G92, G76

G32: Thread cutting G92: thread cutting fixed cycle G76: thread cutting compound cycle

Turning processing: G70, G71, 72, G73

G71: Axial roughing compound cycle command G70: Finishing compound cycle G72: Face turning, radial roughing cycle G73: Profile roughing cycle

Programming method G90, G91

G90: Positive coordinate programming G91: Incremental coordinate programming

Spindle setting command

G50: Spindle maximum speed setting G96: Constant line speed control G97: Spindle speed control (undo constant line speed control command) G99: Come back to point R (center hole) G98: Come back to reference point (final hole)

Spindle forward rotation stop command M03, M04, M05

M03: Spindle forward transmission M04: Spindle rotation M05: Spindle stop

Cutting fluid switch M07, M08, M09

M07: Mist cutting fluid is on M08: Liquid cutting fluid is on M09: Cutting fluid is off

Movement stop M00, M01, M02, M30

M00: Program pause M01: Program abort M02: Machine reset M30: Program ends, the pointer comes back to the beginning

M98: Calling a subroutine

M99: Come back to the main program
