切削力理论公式的计算值往往与实测值相差较大.本文采用多元线性回归方法，通过对实验数据的统计分析，导出了变形系数ξ，摩擦角β与切削要素ap，f，V之间的函数公式，阐明了经验公式与理论公式之间差别原因，分析了理论公式的局限性.

The theoretical formula of cutting force usually is a significant difference from the measuring value. The article, using statistics and analysis of the experiment data with the multi-linear regressing method, derives the function of deformed coefficient ξ, rub angle β, and cutting essentials such as ap, f, V, then suggests the quantitative connections between the theoretical formula and experience one. Finally the insufficiency of the theoretical formula is explained.
