What is the difference between G code and M code?
The difference between G code and M code:
G codes are geometric codes, while M-codes are related to machine functions. G codes are used for product design, while M codes are related to stopping/starting the machine. G codes activate numerically controlled (NC) machines, while M codes activate the machine’s PLC.
What does N in G code mean?
N:N value gives the line number. G: The G number tells the tool when to move and stop. X, Y, Z: These values represent the tool’s position in three dimensions – X for horizontal, Y for vertical, and Z for depth. F: F is related to the speed at which the machine feeds the workpiece.
