Looking to dive into the world of computer-aided manufacturing? Look no further than G-code and M-code.
These programming languages are essential for controlling automatic machine tools, and are widely used in the industry.
Whether you’re a beginner or an experienced professional, understanding G-code and M-code is crucial for success in the field.
In this comprehensive guide, we’ll break down everything you need to know about these languages, from their history and versions to their most common instructions and functions.
With this knowledge, you’ll be able to program your own CNC machines with confidence, and take your manufacturing skills to the next level.
So what are you waiting for? Let’s dive in and discover the power of G-code and M-code!
What is G-code?
G-code (also known as RS-274) is the most widely used NC programming language.
It has many versions and is mainly used to control automatic machine tools in computer-aided manufacturing.
G code is sometimes called G programming language.
G code is the instruction in the numerical control program. Commonly referred to as the G instruction.
G code can be used to realize rapid positioning, inverse circle interpolation, along circle interpolation, middle point arc interpolation, radius programming and jump processing.
What is M-code?
M code is defined as auxiliary function code in FANUC program.
M code plays an auxiliary control role for the machine tool and is used for non axis movement command.
