G-code is the name of a plain text language that is used to guide and direct cnc machines. For most modern cnc machines, it isn’t necessary to know the meaning of g-codes since cad and cam software is translated into g or m codes to instruct a cnc machine on how to complete a process.
Computer numerical control (cnc) is a method of automating control of machine tools through the use of software embedded in a microcomputer attached to the tool. With cnc, each object to be manufactured gets a custom computer program, usually written in an international standard language called g-code, stored in and executed by the machine control unit(mcu).
Cnc services suppliers across the world use cnc controls with the programming language to instruct the operation of the machine tool.

G code for free! i have created a simple g code example for you to download to test out your cnc mill and practice your workflow for clamping the stock and setting up your cnc machine. There are a few free g code files online, but they always lack any information about tooling, datum positions or even the size of material you need.
