G codes , M codes
• G code: Preparatory Function are used to set the control for various machine movement such as:
• Linear interpolation G01• Rapid travers G00• Circular interpolation G02, G03
• M code: Miscellaneous function direct the controller to execute the function indicated such :
• End of program M02, M30• Tool Change M06• Turn the coolant off M09
