在把金刚石看成球体、把岩石看成具有库仑塑性的模型下,介绍了金刚石“犁”式切削作用的理论;确定了金刚石切削面上的应力分布、切削力、破碎体积和破碎功的表达式;并与一些实验结果作了比较。
The theory of “plow” diamond cutting is introduced under the model of diamond as a sphere and the rock as Coulombic plasticity. The expression of stress distribution, cutting force, crushing volume and crushing work on the diamond cutting face is determined Formula; and compared with some experimental results.
