suresh What is the difference between G-code and M-code in CNC machining?
In CNC machining, G-code and M-code are essential components used to control the operation of the machine. While both codes are alphanumeric instructions, they serve different purposes in the machining process.
G-code: G-codes are codes that control the movements of the machine tool. They are used to specify different operations such as cutting speeds, feed rates, tool positioning, and toolpath direction. G-codes are essential for controlling the motion and positioning of the machine during the machining process.
M-code: M-codes, on the other hand, are codes used to control auxiliary functions of the CNC machine. These functions include turning the coolant pump on or off, changing the spindle speed, controlling the tool changes, and stopping or starting the machine. M-codes are used to control various operations that are not related to the actual motion of the machine.
In summary, G-code controls the motion of the machine tool, while M-code controls auxiliary functions and operations of the CNC machine. Both codes work together to ensure the smooth and efficient operation of the CNC machining process.
