摘要：采用多元线性回归分析方法研究了切削速度、进给量和切削深度对铣削力的影响规律，借助最小二乘法原理对切削力经验公式回归系数进行参数估计和优化，并对经验公式进行相关性检验。检验结果表明，相关显著性很高。

Abstract:By using multivariable linear regression method，the influences of the cutting speed，feed rate and cutting depth on the milling force are investigated.By means of least square method，the regression coefficients in the empirical cutting force formula are estimated and optimized.The correlation test for the empirical formula is also carried out.The test result shows that the correlation saliency is highly significant.
Keywords:cutting parameter；cutting force；least squares method
