Machined surface quality improvement measures affecting factors and Research

摘要

The use of mechanical products to improve performance and increase the service life of components and composition of the product processing quality is closely related to machining quality is the basis of product quality assurance. Measure of good or bad quality parts machining the main indicators are: machining accuracy and surface roughness. This paper mainly affect parts of the surface roughness factor, parts of the surface layer of the physical and mechanical properties (surface work hardening, residual stress, microstructure change and grinding burn), surface quality performance parts and other factors affecting the analysis and research to improve the quality of machined surface process measures. A parts failure or sudden damage, except for a few reasons due to ill-designed and strong enough, or because of an accident caused by accidental overload or damage caused by a failure outside, mostly due to wear, corrosion by the external environment or fatigue damage. Wear, corrosion, and fatigue failure occurred in parts of the surface, or from the beginning of the part surface. Therefore, the surface quality will directly affect the use of performance parts, and thus the surface quality problems gaining importance in all aspects.
