前言机械零件的破坏,一般总是从表面层开始的。产品的性能,尤其是它的可靠性和耐久性,在很大程度上取决于零件表面层的加工质量。研究机械加工表面质量的目的就是为了掌握机械加工中各种工艺因素对加工表面质量影响的规律,以便运用这些规律来控制加工过程,最终达到改善表面质量 Preface The destruction of mechanical parts, generally always start from the surface layer. Product performance, especially its reliability and durability, depends largely on the quality of the part surface finish. The purpose of studying the surface quality of machining is to grasp the rules of various process factors on machining surface quality in machining so as to control the machining process by these rules and finally to improve the surface quality
