The G-code future is in jeopardy. There are changes to try to create a new standard. The new standard where you can go straight from CAM or CAD right to the CNC machine.
Basically this is an attempt to try to eliminate a step in the CNC Process. Others have tried to eliminate or update G-code before. Its simplicity has won out, so far. It has survived.
What are M-Codes?
M-Codes are other codes that are throughout in the CNC Program. Think of them like the lesser cousin of G-Codes. M-Codes are generally very specific to the machine. For instance, “M03” might stand for “Torch Off” on a CNC Plasma Cutter. It also stands for “Spindle Turn Clockwise” on a CNC Mill or CNC Router.
M-Codes
- M0 - program stop
- M1 - optional program stop
- M2 - program end
- M3 - turn spindle clockwise
- M4 - turn spindle counterclockwise
- M5 - stop spindle turning
- M6 - tool change
- M7 - mist coolant on
- M8 - flood coolant on
- M9 - mist and flood coolant off
- M26 - enable automatic b-axis lamping
- M27 - disable automatic b-axis clamping
- M30 - program end, pallet shuttle, and reset
- M48 - enable speed and feed overrides
- M49 - disable speed and feed overrides
- M60 - pallet shuttle and program stop
