CNC G Code and CNC M Code
G-code is the programming language used to control CNC machinery. A program is a sequence of codes and data that tells the machine what to do. The programmed codes, along with the right tooling in a CNC machine center, allow for correct and repeatable part manufacturing. G-code makes CNC machines consistent to program and flexible, able to produce different parts. Simply put, G-code is a software programming language used to control a CNC machine. And, even with complex CNC machining, G-code is written in a straightforward, logical way.
It moves the tool to part geometry at the maximum rate and is generally used to move the tool and part from near to far or vice versa. These codes, such as G00, are followed by a geometric location. G-code can repeat an action indefinitely until it is stopped. For example, G01 followed by a sequence of X, Y, or Z positions, means all linear feed moves occur at G The X and Y axes position the spindle precisely to perform a cut or other function.
M-code controls miscellaneous functions , and typically these can be thought of as non-geometry machine functions. Examples include spindle rotation start and stop, coolant on and off, pallet change, etc.
Some of these functions may vary by the specific machine. Unlike G-code, however, M-code can be more specific for different machines and is more customizable. Both types are needed to have a CNC machine perform its functions.
Like any language, CNC has many other aspects to it. This chart is just a sampling of all the program lines that could be included in the code. Some examples of code programming lines and what they mean. Anything in parentheses is not read by the machine.
These are comments for the programmer and operator. So far, the program has set the geometry and the spindle speed. CNC lathes use G-code and M-Code too, but you can expect some different commands and sequences for turning. While machines are frequently programmed directly with G-code, a CNC programmer often uses a high-level computer aided manufacturing CAM programming tool.
Mastercam is a code-producing software that helps programmers create the right code for the project. Standard in the CNC industry, Mastercam takes input from the programmer everything it needs to do , and it produces the right G- and M-codes.
The programmer imports a machine model and the machining fixture. Then, the programmer selects the tools and the tooling paths of where the spindle will go, and the code is produced by the software. The programmer works with the CAD models, but refers to the print for the exact specifications and tolerances.
As powerful as Mastercam is, it could require two weeks of programming if the part is complex large size and many tools needed , yet it could only take two hours for a simple part.
Obviously, a 3-tool job is simple compared to a tool job. Mastercam software shows a visual of the entire project; at left are folders containing the code needed to perform various functions. Depending on your job responsibilities , maybe reading this article is all you need to know about CNC programming using G-code and M-code.
Or, you may need to dig deeper to properly execute your daily duties. Within a CNC machine shop, knowing something about code is helpful for many positions. Shops with a good internal training program will explain the basics of coding to new employees during the orientation process. Others may include it as part of on-the-floor training for operators. Depending on the part and process, the CNC machine center and program run repeatedly with limited interaction.
The operator loads, unloads, inspects, deburs parts, and packages the part. Many projects, however, require slight adjustments, like adjusting work offsets and tool wear. Editing is possible on the shop floor, but it requires a key to enable editing.
Editing is mostly reserved for experienced engineers, setup pros, and supervisors. Well, at least you know more about G-code and M-code and some other related commands. Maybe you want to learn more about CNC tooling practices such as … What tool is needed? When should a shop invest in tools? How do you implement new tooling solutions?

CNC Machine G Codes and M Codes – CNC Milling and Lathe
Numerical control NC refers to the automation of machine tools that are operated by abstractly programmed commands encoded on a storage medium, as opposed to controlled manually via handwheels or levers, or mechanically automated via cams alone. The first NC machines were built in the s and s, based on existing tools that were modified with motors that moved the controls to follow points fed into the system on punched tape. It moves each axis at its max speed until its vector is achieved. Shorter vector usually finishes first given similar axis speeds. G01 Linear interpolation M T The most common workhorse code for feeding during a cut.
G-code is the programming language used to control CNC machinery. A program is a sequence of codes and data that tells the machine what to do. The programmed codes, along with the right tooling in a CNC machine center, allow for correct and repeatable part manufacturing. G-code makes CNC machines consistent to program and flexible, able to produce different parts. Simply put, G-code is a software programming language used to control a CNC machine.
Modern CNC machines operate on programs, which is why operators must know the types of code at their disposal and how to use them. While the most common programming language used by CNC software is G code, M code also has specific applications. When it comes to G code versus M code, one isn't necessarily better than the other. Instead, both types are needed to have the system perform the desired operations. As with any computer, it operates based on a specific language the system understands to complete certain tasks. This operational language requirement is where instructions come into CNC programming. Operators may choose to input the programs manually or use CAM software.

It is used mainly in computer-aided manufacturing to control automated machine tools, and has many variants. G-code instructions are provided to a machine controller industrial computer that tells the motors where to move, how fast to move, and what path to follow. The same concept also extends to noncutting tools such as forming or burnishing tools, photoplotting , additive methods such as 3D printing , and measuring instruments.
