The concept of surface roughness of the cutting machine

In mechanical parts manufacturing process, tool or wheel knife left over anthrax and chip separation of plastic and machine tool vibration and other factors, the part that makes access to friends on the surface, always leaves a fine fine pitch and peak-Valley formed by the rough, the bumpy in rough surface can be seen with the naked eye.

Fine added: after the surfaces with a magnifying glass or microscope can observe, this surface has a small peak to Valley height and spacing is called also called micro-roughness of surface roughness.
