What is the G code and M code of the CNC and VMC M/C for Fanuc and Siemens systems

 

What is the G code and M code of the CNC and VMC M/C for Fanuc and Siemens systems

 CNC that mean computer numerical control and VMC mean vertical machining center. This machine control by the M code and G code

What is the M code:- M code is the miscellaneous machining function and control programs start and stopping. this command for use instant, M03 start spindle, M72 part count, coolant on and off , M06 tool change and help the operators

What is the G code:- G code is the preparatory command , which is controls the CNC program. Use of G code we can create program and control of the program ,tool and job like rapidly transverse, create thread, drilling, boring  counter, milling and other operation du by the use G & M code
