The surface roughness of CNC machined parts

CNC machining can manufacture the part with tight tolerance requirements and fine parts of various metals or plastics, and is one of the best machining methods for custom parts and prototype production. During CNC machining, raw material is selectively and precisely removed to produce the part that approximate the final shape. This machining process is also commonly referred to as subtractive manufacturing. As the CNC cutting tool continuously removes raw material during machining, visible cutting tool marks will be created on the surface of the part. For the definition of finish of these cutting tool marks, we call it the surface roughness of CNC machined parts and divide it into various roughness grades.
