What does "CNC" programming involve?

CNC programming primarily involves writing and inputting commands for operations, which directly control the automated processes of CNC machines. This programming utilizes specific languages, typically G-code and M-code, to dictate the movements, speeds, and functions of machining tools. By defining precise instructions, operators can achieve intricate cuts, shapes, and finishes on various materials, thus allowing for a high degree of accuracy and repeatability in manufacturing.

While manual control of machines and performing repairs are important skills in the overall machining field, they do not fall under the umbrella of CNC programming specifically. Manual control refers to hands-on operation without automation, and repairs involve troubleshooting and fixing machinery rather than programming it. Designing parts for machining is a separate activity that often precedes programming, as it requires the creation of CAD drawings and specifications before translating that design into CNC commands. Thus, the essence of CNC programming centers around the formulation and execution of code to automate and streamline the machining process.
