本研究以切削实验为基础 ,建立出钻削加工中毛刺形成的切削模型 ,并对其生成与变化进行了系统的实验研究与理论分析 ,揭示了钻削加工中毛刺形成与变化的基本规律 ,开发了若干抑制或减少毛刺的新技术、新工艺和新方法 In this study, the cutting model of burr formation in drilling was established based on the cutting experiment, and the generation and variation of the burr cutting model were systematically studied and theoretically analyzed. The basic rules of burr formation and variation in drilling were revealed. Several new techniques, new processes and new methods have been developed to suppress or reduce burrs
