CNC Machining Technology Overview

What is CNC machining?

CNC machining is an automated manufacturing process in which computer numerical control (CNC) systems are used to control tools and machines to cut, shape, and process various materials to make parts, components, and products.

Example of CNC machining parts

What are the applications of CNC machining?

CNC machining is widely used in industries such as aerospace, automotive, medical, and industrial equipment due to its ability to effectively produce precision parts using production grade materials. Typical applications of CNC machining include:
– Aerospace components
– Prototypes for product development
– Medical implants and instruments
– Circuit board prototypes
– Automotive engine parts
– Wind turbines

What is CNC machining process?

CNC machining involves the use of computer programs to control machines for the precise manufacturing of complex components. To start, a designer uses computer-aided design (CAD) software to create a geometric model of the component. Then, a process engineer translates this model into CNC code, which comprises detailed instructions for cutting, movement, and machining.

This program uses G-codes and M-codes to describe the tool’s path, speed, cutting depth, and more. The CNC machine tool follows these instructions, moving the tool to cut and shape the raw material, such as metal or plastic, into the desired component. The high-precision movements of the machine tool and tool ensure that the final component meets the design requirements, with the necessary dimensions, surface quality, and geometric shape.

Which is better CNC or 3D printing?


CNC machining is preferred when you need strong, precise parts from a variety of materials, whereas 3D printing is ideal for quickly producing complex and customized designs. Your choice depends on material, part complexity, precision, and production quantity.
