G-Code and M-Code are essential for CNC machining, and understanding them is crucial for working in a CNC machine shop. G-Code controls the machine’s movement and dictates the end product, while M-Code is used for specific functions and actions. Together, these codes fabricate CNC machined parts.
The history of CNC programming dates back to the late 1950s, and G-Code has evolved to include macro language capabilities. Previously, CNC machines were operated with cards and tapes, but now they are controlled using computer-based programming. CAD/CAM software generates G-Code and M-Code, allowing for accurate and efficient fabrication.
G-Code is written in a logical language and includes commands for rapid movement, linear feed move, clockwise and anticlockwise feed move, and more. M-Code controls non-cutting machine operations such as spindle start and stop, tool changes, and coolant control.
CNC files, also known as G-Code files, contain design geometry, tool paths, machine commands, and material specifications. Different CNC file formats exist, such as DXF, DWG, IGES, STEP, and STL, each with its own characteristics and uses.

What are G and M Codes?
G and M Codes are two fundamental types of CNC machined codes used in CNC machining, which is a computer-based manufacturing process. G-Code is the most commonly used CNC machine programming language. It acts as a controller and governs the movement of the machine to create the desired CNC machined product. On the other hand, M-Code is utilized for specific applications and controls various machine functions, such as initiating or stopping actions or programs.
Both G-Code and M-Code work hand in hand to fabricate CNC machined parts and components in various industrial sectors. G-Code primarily focuses on the movement aspect and geometry of the part being machined. It consists of commands for rapid movement, linear feed move, clockwise and anticlockwise feed move, and many other functionalities. M-Code, on the other hand, handles non-geometrical machine functions, such as starting and stopping the spindle, tool changes, and coolant control.
In CNC machining, a comprehensive understanding of G and M Codes is crucial for ensuring accurate and efficient fabrication of CNC machined parts. These codes play a vital role in the manufacturing process, allowing operators and machinists to control the machine’s actions and functions with precision.
Having a firm grasp of G and M Codes enables machinists to create intricate and complex products and achieve the desired level of precision. These codes are the building blocks of CNC programming, providing instructions to the CNC machine on how to operate, move, and carry out various machining operations.
History of CNC Programming
The history of CNC programming dates back to the late 1950s when the MIT Servomechanisms Laboratory developed the first implementation of numerical control programming. This marked a significant milestone in the evolution of manufacturing technology.
During the early stages, CNC programming primarily relied on G-Code, a language that controlled the movements of CNC machines. G-Code allowed for the precise positioning and machining of parts.
In 1960, the Electronic Industry Alliance standardized the numerical control programming language in the United States. This standardization aimed to enhance interoperability and compatibility among CNC machines from different manufacturers. The final revision of the standardized language, which included G-Code, was approved in 1980.
Introduction of BCL (Binary Cutter Language)
One standardized version of G-Code known as Binary Cutter Language (BCL) emerged during this period. BCL enabled CNC machines to execute commands for straight lines and arcs, enhancing the sophistication and versatility of the machining process.
Over the years, tool builders have continuously worked to standardize machine tool controllers to address compatibility issues and streamline operations. This standardization allowed CNC machines to seamlessly read and execute G-Code instructions, regardless of the brand or model.
CAD/CAM Applications and the Evolution of G-Code
In 2010, the development of Computer-Aided Design/Computer-Aided Manufacturing (CAD/CAM) applications brought significant advancements to CNC programming. These applications allowed for the generation of intricate designs and the automatic conversion of those designs into G-Code.
G-Code has also evolved to include macro language capabilities, making it more akin to high-level programming languages. This advancement has expanded the possibilities for complex machining operations and paved the way for even greater precision and efficiency in CNC programming.

The Role of Machine Programming in CNC Machining
The role of machine programming is critical in the CNC machining process. The “C” in CNC programming stands for “Computer,” highlighting the central role of computers in operating the programming machine system. CNC machines can only understand specific programming languages, making accurate and precise machine programming essential for successful CNC machining.
Before computer-based machine programming, maintaining correct programs for multiple machining tasks was challenging due to the paper format of NC programming. However, the introduction of computers revolutionized the process, resolving production issues and improving efficiency. While manual coding was still labor-intensive, advanced computers and CAD/CAM software significantly streamlined CNC programming, making it more efficient and easier to execute.
Machine programming involves inputting programs into the CNC system, either manually or using CAD software. Accuracy is crucial, as even minor errors in the code can lead to significant issues during machining. The programming code needs to be precise and flawless to ensure the CNC machine produces the desired output with precision and consistency.
With the advent of computer-based programming, CNC machines have become more versatile and capable of executing complex tasks. Computer-Aided Design (CAD) software plays a significant role in generating accurate machining programs, enabling machinists to translate digital designs into G-Code and M-Code instructions that CNC machines can understand and execute.
The role of machine programming in CNC machining cannot be overstated. It is the backbone of the entire process, controlling the movements, functions, and operations of CNC machines. Accurate programming ensures precise and efficient manufacturing, allowing businesses to produce high-quality CNC machined parts and components.
