CNC Machining Overview

Professional Engineering Support

CNC Machining, short for Computer Numerical Control Machining, is a manufacturing process utilizing computer-controlled machinery to remove material layers, resulting in precise parts or components. This method combines tooling and precise machine movement to produce parts according to exact specifications.

The CNC machining process commences with designing a part in CAD software, followed by converting the design into machine commands using CAM software. Subsequently, the CNC machine interprets these commands to cut and shape the material precisely, ultimately creating a finished part identical to the digital design.

CNC Machining offers unparalleled precision and repeatability, making it highly sought-after in industries requiring intricate parts. Its versatility in handling various materials, coupled with rapid production times and consistent quality, positions it as a fundamental technique in contemporary manufacturing.

In contrast to 3D printing, which is an additive manufacturing method, CNC machining operates as a subtractive process, starting with a solid block of material and removing sections until the desired part is achieved. While 3D printing is preferred for complex geometries and rapid prototyping, CNC machining excels in durability, precision, and material versatility.
