CNC is the abbreviation that refers to computer numerical control. CNC machining is the manufacturing process that creates the final product by removing material using a cutting tool, where computers play a significant role in guiding the motion of both the machine and the cutting tool to accomplish extremely accurate movements. Unlike human labor, the implementation of CNC machining enables the automation of the manufacturing process, improving precision and efficiency.
