What type of programming language is predominantly used in CNC machining?

CNC machining predominantly utilizes G-code as its programming language. G-code, or Geometric Code, is a standardized language that provides instructions for CNC machines to perform various tasks. This includes commands for moving the tool, controlling spindle speed, and setting the feed rate. Each line of G-code corresponds to specific movements and actions that the CNC machine must execute to accurately produce a part.

The importance of G-code in CNC machining lies in its ability to directly translate design parameters from CAD (Computer-Aided Design) models into actionable commands that guide the machine's operations. Because G-code is widely accepted across different types of CNC equipment, it allows for portability of programs and consistency in machining practices, making it integral to the industry. Other programming languages, like Python or JavaScript, do not serve the same specific purpose in the context of CNC machine operations, and HTML is used for structuring content on the web rather than for machine programming.
