Part programming for CNC machine

Part programming is a program done for the production of a component by using standard codes known as the part program.

G-codes: These are the general-purpose codes. Some of the G codes with their purpose are:

G-code	Purpose
G00	Point to point countering
G01	Linear travel
G02	Circular interpolation, clockwise
G03	Circular interpolation, anti-clockwise
G04	Dwell
G05	Hold
G08	Acceleration
G09	Retardation
G17	XY plane selection
G18	XZ plane selection
G19	YZ plane selection

M-codes: These are the miscellaneous codes that tell a machine how to act.

Some of the M-codes with their purpose are:

M-code	Purpose
M00	Program stop
M01	Optional program stop
M03	Spindle start clockwise
M04	Spindle start anti-clockwise
M05	Spindle stop
M06	Tool change
M08	Coolant On
M09	Coolant Off
M30	End of program/return to start
