M code in CNC

M code:

               M code, it is also called Machine code, in cnc part program playing an important role. This code specially used for machining operations like coolant on-off, spindle runs and stop, chuck clamp-declamp, tailstock reverse and forward, etc. 

  

Here we are given you some M codes for your information:

              

Sr. No	M codes	Specification
1.	M00	Program Stop
2.	M01	Optional Stop
3.	M02	Program End
4.	M03	Spindle rotate in a clockwise direction
5.	M04	Spindle rotate in Counterclockwise direction
6.	M05	Spindle Stop
7.	M06	Tool Change
