Introduction to CNC Cutting

What Is CNC Cutting?

Computer Numerical Control (CNC) cutting is a highly specialized process that relies on computer-aided design (CAD) and programming to direct the precise operations of the cutting equipment. At the heart of CNC cutting is a keen ability to translate digital designs into physical objects and, thus, perform intricate and complex cuts that would normally be beyond the scope of manual systems. This type of technology is quite important in the manufacturing process since tasks can be automated, reducing the required manual intervention, which often tends to be error-prone. Hence, CNC cut parts that move along predefined paths with minimum tolerance, guaranteeing consistent production quality. The precision with which a CNC machine is capable of cutting is because the machine follows program instructions written in G-code, a programming language for CNC machining that coordinates the exact movements and operations of the machine. This makes it one of the most highly utilized fabrication methods across different industries.
