机械设备零件的损坏,很大程度总是从零件表面开始的。研究机械加工表面质量,其目的就是为了掌握机械加工中各个工艺对加工表面质量影响的规律,以便利用这些规律来控制加工过程,最终达到改善产品质量,增强产品使用性能的目的。 Mechanical parts damage, to a large extent always from the surface of the parts. The purpose of studying the surface quality of machined surface is to grasp the rules of the influence of each process on the machined surface quality in order to control the machining process by these rules and finally achieve the purpose of improving the product quality and enhancing the product performance.
