M Code
| Code | Description | Milling ( M ) | Turning ( T ) | Corollary info |
|---|---|---|---|---|
| M00 | Compulsory stop 强制停止 | M | T | Non-optional—machine will always stop upon reaching M00 in the program execution. 每当读到M00机器就会强制停止操作。 |
| M01 | Optional stop 选择性停止 | M | T | Machine will only stop at M01 if operator has pushed the optional stop button. 当OP1按钮启动后，程序就会在M01出现时停止机器。 |
| M02 | End of program | M | T | No return to program top; may or may not reset register values. |
| M03 | Spindle on (clockwise rotation) 顺时正转。 | M | T | |
| M04 | Spindle on (counterclockwise rotation) 逆时反转 | M | T | |
| M05 | Spindle stop | M | T | |
| M06 | Automatic tool change (ATC) 转换刀具 | M | T (some-times) | |
| M07 | Coolant on (mist) 冷却剂开启 | M | T | |
| M08 | Coolant on (flood) 冷却剂开启 | M | T | |
| M09 | Coolant off 冷却剂关闭 | M | T | |
| M10 | Pallet clamp on | M | T | For machining centers with pallet changers |
| M11 | Pallet clamp off | M | For machining centers with pallet changers | |
| M13 | Spindle on (clockwise rotation) and coolant on (flood) | M | This one M-code does the work of both M03 and M08. It is not unusual for specific machine models to have such combined commands, which make for shorter, more quickly written programs. | |
| M19 | Spindle orientation 主轴定位并且锁定 | M | T | Spindle orientation is more often called within cycles (automatically) or during setup (manually), but it is also available under program control via M19. The abbreviation OSS (oriented spindle stop) may be seen in reference to an oriented stop within cycles. |
| M21 | Mirror, X-axis | M | ||
| M21 | Tailstock forward | T | ||
| M22 | Mirror, Y-axis | M | ||
| M22 | Tailstock backward | T | ||
| M23 | Mirror OFF | M | ||
| M23 | Thread gradual pullout ON | T | ||
| M24 | Thread gradual pullout OFF | T | ||
| M30 | End of program with return to program top 结束程序并且回到程序开头处 | M | T | |
| M41 | Gear select - gear 1 | T | ||
| M42 | Gear select - gear 2 | T | ||
| M43 | Gear select - gear 3 | T | ||
| M44 | Gear select - gear 4 | T | ||
| M48 | Feedrate override allowed | M | T | |
| M49 | Feedrate override NOT allowed | M | T | This rule is also called (automatically) within tapping cycles or single-point threading cycles, where feed is precisely correlated to speed. Same with spindle speed override and feed hold button. |
| M60 | Automatic pallet change (APC) | M | For machining centers with pallet changers | |
| M98 | Subprogram call 呼叫子程序 | M | T | Takes an address P to specify which subprogram to call, for example, "M98 P8979" calls subprogram O8979. |
| M99 | Subprogram end 结束子程序并回到主程序 | M | T | Usually placed at end of subprogram, where it returns execution control to the main program. The default is that control returns to the block following the M98 call in the main program. Return to a different block number can be specified by a P address. M99 can also be used in main program with block skip for endless loop of main program on bar work on lathes (until operator toggles block skip). |
