It is used mainly in computer-aided manufacturing to control automated machine tools. G-code is a language in which people tell computerized machine tools how to make something. The first implementation of a numerical control programming language was developed at the MIT Servomechanisms Laboratory in the late 1950s. G-code has often been used in these implementations. Extensions and variations have been added independently by control manufacturers and machine tool manufacturers, and operators of a specific controller must be aware of differences of each manufacturer’s product.

Developed at MIT, BCL was developed to control CNC machines in terms of straight lines and arcs. During the 1970s through 1990s, many CNC machine tool builders attempted to overcome compatibility difficulties by standardizing on machine tool controllers built by Fanuc. Siemens was another market dominator in CNC controls, especially in Europe. Some CNC machines use “conversational” programming, which is a wizard-like programming mode that either hides G-code or completely bypasses the use of G-code.

It was unable to encode logic, but was just a way to “connect the dots” where the programmer figured out many of the dots’ locations longhand. G-codes, also called preparatory codes, are any word in a CNC program that begins with the letter G. People have pointed out over the years that the term “G-code” is imprecise. But every letter of the English alphabet is used somewhere in the language. Nevertheless, “G-code” is established as the common name of the language. Bold below are the letters seen most frequently throughout a program. Positive rotation is defined as a counterclockwise rotation looking from X positive towards X negative.

Defines diameter or radial offset used for cutter compensation. D is used for depth of cut on lathes. It is used for aperture selection and commands on photoplotters. Defines arc center in X axis for G02 or G03 arc commands. Also used as a parameter within some fixed cycles.
