CNC Machining, or Computer Numerical Control Machining, is a manufacturing technique where computer-controlled devices are used to remove layers from a material, creating detailed parts or components. Through a combination of tooling and precise machine movement, it produces parts to exact specifications.
The CNC machining process begins by designing a part in CAD software. This design is then converted into a set of machine commands using CAM software. The CNC machine reads these commands to precisely cut and shape the material, producing a finished part that matches the digital design.
CNC Machining offers unparalleled precision and repeatability, making it a top choice for industries requiring intricate parts. Its ability to handle a variety of materials, from metals to plastics, combined with fast production times and consistent quality, makes it an essential method in modern manufacturing.
3D printing is an additive manufacturing method, building parts by depositing material layer by layer. In contrast, CNC machining is a subtractive method, starting with a solid block of material and removing sections until the desired part is achieved. While 3D printing is often favored for complex geometries and rapid prototyping, CNC machining excels in durability, precision, and material versatility.
