Factors of surface roughness formation

The surface formed by cutting or other methods of parts always has geometric shape error due to plastic deformation of materials, mechanical vibration, friction and other reasons in the processing. Due to the different processing methods and workpiece materials, the depth, density, shape and texture of the traces left on the machined surface are different.

Effect of surface roughness on workpiece

Surface roughness has an important impact on the service life and reliability of mechanical products, as follows:

Influence wear resistance

Affect the stability of the fit

Influence fatigue strength

Influence corrosion resistance

Affecting the tightness

Influence contact stiffness

Influence the measurement accuracy

Other effects on liquid, gas, current, resistance, reflection, radiation, etc
