摘　　要：从切削几何、微元切削机理和刀齿轨迹计算理论角度推导了铣削力的几何理论解、近似积分解、精确积分解和简易计算四种方法。数值计算表明,当进给速度很小时,四种方法计算值近似相等,简易计算公式形式简单,可用于铣削面积和材料去除率的计算。当进给速度较大时,采用简易计算法(或几何理论解、近似积分解)的计算值会产生较大误差。Respectively from the cutting geometry,infinitesimal cutting mechanism and tooth trajectory calculation derived theoretical point of view of the geometric theory of milling force solution,approximate integration solution,exact calculation of integral solutions and simple four methods. Numerical calculations show that,when the feed rate is very small,four methods to calculate the value approximately equal,simple formulas and forms,can be used in the milling area and the material removal rate calculations. When the larger feed rate,the use of simple calculation method（ geometric or theoretical solution,approximate integration solution） the calculated value will lead to considerable error.
