Background

The surface roughness refers to the small pitch and the unevenness of minute peaks and valleys of the processed surface. The distance between two wave crests or two wave troughs (wave distance) is very small (below 1 mm), and the micro geometrical shape error belongs to. The smaller the surface roughness, the smoother the surface, which is generally caused by the machining method used and other factors, such as friction between the tool and the surface of the part during machining, plastic deformation of the surface layer metal during chip separation, and high frequency vibrations in the process system. Due to the difference of the processing method and the circular workpiece material, the depth, density, shape and texture of the trace left on the processed surface are different, the surface roughness has close relation with the matching property, wear resistance, fatigue strength, contact rigidity, vibration, noise and the like of the mechanical part, and the method has important influence on the service life and reliability of the mechanical product. In the existing roughness inspection process of the circular workpiece, a fixed inspection tool is not used, the circular workpiece is generally fixed by splicing and matching various detection fixing blocks, the circular workpiece is fixed and complex, the inspection efficiency is low, the circular workpiece is fixed and unstable, and the roughness inspection precision is easy to deviate.
