摘要
本文建立了金属切削加工中切削方向毛刺与亏缺的生成模型。给出了切削方向毛刺和亏缺的判别准则,并对其主要影响因素进行了实验研究和理论分析,揭示出切削方向毛刺与亏缺的界限转换条件为:ε=3,为进一步深入研究提供了理论依据。
In this paper, the forward burr and fracture new model in metal fcutting have been set tip, Distinguish standard of forward burr and aracture are gave and its main influence factors have been experimented nd studied pointting out limit change coadition of forward burr and fracture: shear shrain ε=3, whieh offers sientific basis forther research.
