摘要
介绍最小二乘法（即回归分析法）在切削力经验公式建立方面的应用，从而使已往的单因素实验转变为双因素实验甚至多因素实验，大大减少了实验次数，节约材料及时间，获得更接近于实际的切削力经验公式。
This paper uses minimun two-multiplication to establishe experience formulas of cutting-force. The former single-factor test can be changed into the double-factor test enven to the multiple-factor test. The test times can be greatly reduced. The materials and time of the test can be also saved. The practical cutting-force experience formuls are given.
