摘　　要：总结了机械加工零件表面完整性的发展及其表征与测量的已有方法和标准。针对零件精加工的表面完整性要求,借鉴美国表面完整性切削加工数据组,提出了表面完整性表征模型,并明确给出了表征模型中各特征的主要表征参数。考虑具体被加工零件及其工艺,同时结合表面完整性内涵,初步构建了机械加工零件的表面完整性概念模型,为机械加工零件表面完整性的控制及其疲劳寿命的提高,提供了理论基础和实施途径。The existing standard and development about description and measurement of surface integrity for machined parts were summarized.According to the requirements of surface integrity for the parts with precision machining,a quantitative model of description for surface integrity was proposed and the parameters of characteristics within the description model were definitely detailed.Considering the specific parts and corresponding machining processes,a conceptual model of surface integrity for machined parts was established by combining the natures of surface integrity.This research offers theoretical basis and feasible operational framework for the control of surface integrity and improvement of the fatigue life for machined parts.
