摘　　要：切削力的理论计算及其准确预报是金属切削领域和刀具设计的重要课题之一。本文给出了考虑刃口半径作用的切削模型 ,分析了临界切削厚度对切削力的影响 。The theoretical calculation and prediction of cutting forces is important in metal cutting research and cutting tool design fields. A general cutting model for the effects of tool edge radius is presented in this paper. The minimum cutting depth gives contribution to the resultant cutting forces. The theoretical predictions of the resultant forces agree well with results of the experiments.
