摘要

摘要磨削过程中磨削裂纹的产生会对工件的使用性能产生不利影响，甚至导致工件报废。然而，磨削裂纹的微观形成机制目前尚不清楚。为此，对凸轮表面磨削裂纹的形貌进行了表征，并从元素组成、微观结构和表面加工硬化等方面分析了磨削裂纹的萌生和扩展行为。根据实验结果和分析，阐明了磨削裂纹的产生机理，并提出了防止磨削裂纹的措施。

Investigation on grinding-induced cracking mechanism of 40Cr steel camshaft

Abstract The generation of grinding cracks during the grinding process will adversely affect the service performance of the workpiece and even cause the workpiece to be scrapped. However, the microscopic formation mechanism of grinding cracks is still unclear at present. In this regard, the morphologies of grinding cracks on the surface of the cam were characterized, and the initiation and propagation behaviors of grinding cracks were analyzed from the perspectives of element composition, micro-structure and surface work hardening. Based on the experimental results and analysis, the generation mechanism of grinding cracks is clarified, and measures to prevent the grinding cracks are proposed.
