Which CNC process uses a laser to cut materials?

The CNC process that utilizes a laser to cut materials is known as laser cutting. This method employs a highly focused beam of light, which can precisely cut through various materials, including metals, plastics, wood, and more. The laser's concentrated energy allows for clean cuts with minimal kerf and excellent detail, making it ideal for intricate designs and components.

Laser cutting stands out in terms of precision and versatility compared to other methods. It can achieve complex geometries and is often favored for its ability to cut through both thick and thin materials efficiently. Additionally, laser cutting produces less mechanical stress on the material being processed, which can be critical for preserving material integrity.

In contrast, the other processes listed each use different methods for cutting materials. Plasma cutting involves ionized gases and high temperatures, waterjet cutting uses jets of water mixed with abrasive materials to cut through, and milling employs rotating cutting tools to remove material. These alternative methods serve different requirements and applications in manufacturing but do not involve the use of a laser.
