G code of cnc

G codes:

                    It is also called the Preparatory function. These codes are given instruction to the machine tool what type of action to perform, such as rapid interpolation, linear interpolation.

                    These codes are the number of specific groups of code, which starts with the letter 'G'. The following table gives different types of G codes and its specifications:      

Sr. No.	G codes	Specification
1.	G00	Rapid Interpolation. Format: G00 X__ Z__;
2.	G01	Linear Interpolation. Format: G01 X__ Z__ F__;
3.	G02	Circular Interpolation in Clockwise direction. Format: G02 X__ Z__ R__ F__;
4.	G03	Circular Interpolation in Counter Clockwise direction. Format: G03 X__ Z__ R__ F__;
5.	G04	Dwell Time. G04 X__; X__: dwell time.
6.	G28	Return to the Reference point. Format: G28 X0.0 Z0.0:
7	G20	Inch Input.
8.	G21	MM Input.
9.	G40	Tool Nose radius Compensation Off
10.	G41.	Tool nose radius compensation in Left side
11.	G42	Tool nose radius compensation in Right side
12	G92	The maximum Spindle speed limit on. Format: G92 S____ M__;
