What diffrance in M code and G code

Question

Accepted Answer

M code and G code are both used in CNC programming, but they serve different purposes.

G code controls the movement and positioning of the machine tool, while M code controls auxiliary functions such as spindle rotation, coolant, and tool changes.
G code is used to specify the tool's path, feed rate, and other motion parameters, while M code is used to activate or deactivate specific machine functions.
Examples of G codes include G01 for linear interpolation, G02 for circular interpolation, and G90 for absolute positioning. Examples of M codes include M03 for spindle on clockwise, M08 for coolant on, and M06 for tool change.
G codes are usually followed by numerical values or parameters, while M codes are typically standalone commands.
Both G code and M code are essential for CNC machining operations, and a combination of these codes is used to program complex operations.

Accepted Answer

G codes: A G code in CNC programming controls the movements of a machine, dictating how and where a machine should move to fabricate a part.
M codes: An M code in CNC programming controls miscellaneous machine functions, including starting and stopping specific actions or programs
