金属切削中进给方向毛刺的生成机理及其控制

A STUDY ON THE LEANED BURR FORMATION IN METAL CUTTING

以切削运动和进给运动方向为基准,对切削毛刺进行了分类,建立了金属切削中进给方向毛刺生成模型.并对其生成机理进行了实验研究和相应的理论分析,揭示了进给方向毛刺生成机理及其主要影响因素.进而提出了抑制进给方向毛刺的若干措施,开发出几种控制和减少进给方向毛刺的新方法.

On the basis of the process of metal cutting, a model for the leaned burr formation in metal cutting is made. Then the principle of forming the leaned burrs is studied, and the related theories are analyzed, thus a clear understanding of the forming process and the influencing factors of the burrs is obtained. Furthermore, a certain number of measures to prevent the burrs are advanced in order to control and decrease the formation of the machining burrs, guarantee and improve cutting quality, and develop new methods to restrain the machining burrs.
