What does the acronym "G-code" refer to in CNC machining?

G-code refers to a programming language used to control CNC (Computer Numerical Control) machines. It consists of a series of commands that instruct the machine on how to move, what speed to operate at, and how to perform various machining tasks. Each G-code command tells the machine specific instructions, such as movements along the X, Y, and Z axes, tool changes, and other machining operations.

In CNC machining, G-code is crucial as it translates the design created in CAD (Computer-Aided Design) software into actual movements of the machine, ensuring precision and accuracy during machining processes. Its versatility and standardization across many CNC machines make it an essential skill for machinists and programmers working in the field. Understanding G-code enables machinists to effectively troubleshoot and optimize machining operations, enhancing productivity and quality in manufacturing.
