磨削划伤成因分析与工程控制

磨削加工是现代装备制造业发展的重要支撑之一。但是，在磨削加工特别是精密、超精密磨削加工过程中，磨削划伤却时有发生，严重困扰着磨削技术的应用与发展。为此，通过大量磨削现场及零件表面磨削划伤查寻与测量，结合切削学、摩擦学、物理学、材料学、影像学相关知识，对磨削工程中各种磨削划伤进行了全面梳理及分析。探究了磨削划伤的主要技术特征；基于砂轮周边磨削和端面研磨二种磨削方式，揭示了单颗磨粒磨削划伤和团聚磨粒磨削划伤形成过程；归纳了影响磨削划伤的主要因素，提出了应对技术措施。

Cause Analysis and Engineering Control Research on Grinding Scratch

Grinding is one of the important supports for the development of modern equipment manufacturing industry.However,in the process of grinding,especially in precision and ultra-precision grinding,grinding scratches occur from time to time,which seriously puzzles the application and development of grinding technology.To this end,through a large number of grinding sites and parts surface grinding scratch detection and measurement,combined with cutting,tribology,physics,materials,imaging related knowledge,all kinds of grinding scratches in grinding engineering were carded and analyzed comprehensively.The main technical characteristics of grinding scratches were investigated;based on the two grinding methods of grinding wheel peripheral grinding and end face grinding,the formation processes of single abrasive grain grinding scratches and agglomerate abrasive grain grinding scratches were revealed,the main factors influencing grinding scratch were summarized,and the technical measures were put forward.
