suresh What is the difference between G-code and M-code in CNC programming?
In CNC programming, G-code and M-code are two types of codes used to control the operation of a CNC machine. Both G-codes and M-codes are essential for directing the movements and actions of the machine, but they serve different purposes.
G-code:
G-code, or geometric code, is used to control the movement of the machine, such as the position, speed, and direction of the cutting tool. G-codes are used for operations such as cutting, drilling, milling, and turning. G-codes specify the tool's path and can include commands for spindle speed, feed rate, and coolant flow.
M-code:
M-code, or miscellaneous code, is used to control auxiliary functions of the machine, such as turning the spindle on or off, changing tools, or stopping the machine. M-codes are used for tasks like tool changes, coolant control, and spindle orientation. M-codes are often used in conjunction with G-codes to perform complex operations.
Overall, G-codes are primarily used for controlling the movement of the machine, while M-codes are used for controlling auxiliary functions. Understanding the differences between G-code and M-code is essential for effectively programming and operating a CNC machine.
