What does the acronym "G-code" stand for in CNC programming?

The acronym "G-code" refers to a language used in CNC (Computer Numerical Control) programming that instructs the machine on how to move and operate. The term essentially derives from "geometric code," which makes sense because it primarily deals with the geometric shapes and paths that the CNC machine needs to follow in order to produce the desired parts or components.

In CNC programming, G-codes dictate various types of movements and operations for the machine. These can include linear movements, circular movements, as well as other essential functions like tool changes or spindle control. Therefore, the connection with geometry is critical, as the code enables machines to understand the spatial commands and execute precise machining operations based on defined parameters.

The other options diverge from the essence of what G-code represents. For instance, "General code for operations" may imply a broader scope but does not capture the specificity of the use related to geometry. "Guided code for user instructions" suggests a focus on user interaction rather than the machine's operational commands. Lastly, "Graphical code for display" implies a visual representation, which is not what G-code entails since it focuses on commands for operational execution rather than graphical output.
