An Introduction to M-Code and CNC Programming

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.

An Introduction to M-Code and CNC Programming

If your work or hobby correlates with CNC machines or 3D printers, then understanding what G-code is and how it works is essential for you. So, in this tutorial we will learn the basics of the G-code language, what are the most important or common G-code commands and we will explain how they work. We use this language to tell a machine what to do or how to do something. The G-code commands instruct the machine where to move, how fast to move and what path to follow. In case of a machine tool such as lathe or mill, the cutting tool is driven by these commands to follow a specific toolpath, cutting away material in order to get the desired shape. Similarly, in case of additive manufacturing or 3D printers, the G-code commands instruct the machine to deposit material, layer upon layer, forming a precise geometric shape. At first glance, when you see a G-code file, it might look a quite complicated but it is actually not that hard to be understood.

The Differences Between G Code and M Code

M-code is the machine control language for CNC machining. It is used in combination with G-code to switch various machine functions off and on. As with G-code, there is some commonality of functions across various controller platforms, but the ultimate definition for any particular M-code function is spelled out by the manufacturer of the control.

The same holds true for CNC machine programming. Even as new manufacturing technologies unfold, the fundamentals for how parts are machined with a CNC program will stay with you forever. At the heart of this automated manufacturing process is a set of instructions that tells a CNC machine where — and how — to move.

CNC G Code and CNC M Code

We give a quick definition of each g-code along with a link to tutorials and examples of how to use it. Mazatrol Training Classes. Move in a straight line at rapids speed. Move in a straight line at last speed commanded by a F eedrate. Clockwise circular arc at F eedrate. Counter-clockwise circular arc at F eedrate.

G code and m codes for cnc programming pdf. G code otherwise called preliminary codes are any word in a cnc program that starts with the letter g is the most generally utilized numerical control nc programming dialect. Want some easy g code training. Basic codes for cnc part programming functions of most common g and m codes g code function m code function g00 rapid linear motion m00 program stop g01 linear motion at preset feedrate f m02 end program g02 circular feed motion cw m03 spindle on cw g03 circular feed motion ccw m04 spindle on ccw. Mand codes which tell the machine to move the table spindle and knee are explained here using a vertical milling machine as an example. Function tells what the g code does notes gives a little more information such as the parameters and tutorial is a link if any to a tutorial that uses g wizard editor to teach how to use the g code.

In the early days of CNC machines, the input or instructions were fed to the CNC machine using punch tapes or magnetic tapes. However, due to technological advancement, computers have replaced them. A computerized CNC controller is shown below. This language is made up of a predefined set of codes called G codes and M codes. Each code has a particular preset function and by using various codes together a workpiece is machined accordingly.
