CNC stands for Computer Numerical Control. It is a computerized manufacturing process in which pre programmed software and code control the movement of production equipment. CNC machining controls a range of complex machinery, such as grinders, lathes, and milling machines, all of which are used for cutting, forming, and creating different parts and prototypes. In daily work, CNC machinists combine elements of mechanical design, technical drawings, mathematics, and computer programming skills to produce various metal and plastic parts. CNC operators can turn metal plates into critical aircraft or automotive parts.

What is a CNC machine tool?

Computer numerical control machine tools are automated machine tools that are operated by a controlled command sequence pre programmed by a computer. CNC machine tools are essentially the opposite of "old-fashioned" equipment, which is manually controlled by handwheels or levers, or only automated by cam mechanisms. Today's modern CNC machine tools use CNC machining language (called G-code) to understand and operate, which tells them precise production measurement values such as feed rate, speed, position, and coordination.

Nowadays, the design and mechanical components of CNC systems are highly automated, which is different from the old and dangerous factory machines you used to think of. The mechanical dimensions of the parts are defined using computer-aided design (CAD) software, and then converted into manufacturing instructions through computer-aided manufacturing (CAM) software. Therefore, it is very important to have knowledgeable CNC machinists and programmers in the industry to operate this high-tech machine.
