The concept of surface roughness
Mar 16, 2018

The concept of surface roughness.

Surface roughness refers to the roughness of the machining surface with smaller spacing and small peak valley. The distance between the two peaks or the two trough (the wave distance) is small (below 1mm), and it belongs to the microscopic geometry error.

Surface roughness is generally adopted by the processing methods and other factors, formed by such as in the processing of the friction between cutter and workpiece surface, plastic deformation of metal in the surface layer on chip separation, and the high frequency vibration, electric machining process system of discharge pit, etc. Due to the different processing methods and workpiece materials, there are differences in the depth, density, shape and texture of the processed surface.
