What is CNC machining?

Mar. 22, 2024

The history of CNC machining dates back to the early 20th century when manual machining processes dominated industrial production. However, it was not until the advent of computer technology that machining underwent a revolutionary transformation. The development of computer numerical control (CNC) systems in the mid-20th century marked a critical moment, enabling automatic control of machining tools with unparalleled precision.


Essentially, CNC machining relies on precision machinery guided by computer instructions to shape raw materials into finished products. The process involves a variety of machining techniques such as milling, turning, and drilling, each customized to specific requirements. At the heart of CNC machining is the complex interplay between CAD/CAM software, which facilitates digital design and programming, and the CNC machine tool, which executes programmed instructions with the highest precision.

How CNC machining works

The process of CNC machining a part begins with conceptualizing its design using CAD software. Once the design is complete, the CAM software generates the necessary tool paths and commands to convert the design into machine-readable code (called G-code). Once the workpiece is securely mounted and the appropriate tools selected, the CNC machine goes to work, carefully carving the material according to programmed instructions. Throughout the process, strict quality control measures ensure that finished parts meet exacting standards.
