Moves the tool at maximum speed to a specific coordinate. Used for non-cutting air moves.
The bread and butter of milling. Moves the tool in a straight line at a defined feed rate .
In the world of , G-code and M-code are the fundamental languages that bring a design to life. While CAD/CAM software does a lot of the heavy lifting today, understanding the underlying code is what separates a basic operator from a master CNC programmer .
Even with modern CAM software, knowing your G and M codes is vital for:
Starts the spindle (clockwise or counter-clockwise). M05: Stops the spindle. M06: Initiates a tool change . M08 / M09: Turns the coolant flood on or off. M30: End of program and reset. 3. Why Manual Coding Still Matters
Accounts for the specific length of the tool being used. 2. What is M-Code? (Miscellaneous/Machine Commands)
Understanding exactly where the tool is headed before you hit the green button.
If G-code is about movement, M-code is about . These commands act like switches to turn parts of the machine on or off.
