切削加工过程中绝热剪切的计算机模拟研究

绝热剪切是切削加工过程中的一个重要现象,绝热剪切的研究对于难加工材料的加工和高速切削的发展都具有重要的意义。这里介绍了切削过程计算机模拟的国内外发展现状,分析了高速切削过程中绝热剪切的计算机模拟研究的各项关键技术。最后,指出了其目前存在的问题和发展方向。

The adiabatic shear is an important phenomenon in cutting, n has important significance to the cutting of the hard - cutting materials and the development of the high speed machining. This paper presents an overview of the study of the computer simulati on of the cutting process in abroad and home . The critic technologies of it are introduced. Eventually, the disadvantage of the computer simulation technology of adiabatic shear and the direction of its development is provided.
