In CNC programming, what do the G and M codes represent?

In CNC programming, G and M codes play a crucial role as they represent the programming instructions that control CNC machines. G codes are primarily used to define movements and paths of the machine, such as linear and circular interpolation, while M codes are used for miscellaneous functions, including controlling the operation of the machine itself, turning on or off the spindle, and other functions.

Understanding that these codes are essential for directing the actions of CNC machinery is fundamental in manufacturing processes. By utilizing these codes, operators can effectively communicate with the machines, providing precise instructions that govern all aspects of the machining process, from speed to tool changes. This knowledge is instrumental for anyone involved in the programming and operation of CNC equipment.
