Study on microscopic characteristics of adiabatic shear bands in the serrated chips formed during high speed machining;
高速切削锯齿形切屑内绝热剪切带微观特征研究
2.
As the high speed cutting proceeds, the cut material yields the continuously plastic deformation at a great strain rate, a large amount of cutting heat is generated, and the phenomenon of local shear slipping occurs, that brings on the coming into being of continuous ribbon serrated chips.
高速车削时被切削材料以极高的应变速率产生连续的塑性变形,产生大量的切削热,在出现集中剪切滑移的情况下,产生了连续型带状锯齿形切屑。
3.
Based on the experimental observation,the high speed formation courses of the continuous banding serrated chips are studied and analyzed.
本文根据实验观察,对高速切削条件下连续型带状锯齿形切屑的形成过程进行了分析研究。
