摘　　要：提出了相对切削力的概念,用以比较在相同加工条件下,不同工件材料切削力的大小。通过试验测量出一组切削力数据,计算出加工几种常用金属材料时的相对切削力,并就其切削加工性进行了分析讨论。对于更多的金属材料,则是利用资料所给出的单位切削力求出相对单位切削力,用以比较其切削力的大小。The concept of relative cutting force is given. The cutting force could be compared for different kind of workpiece materials under the same cutting condition. Through the experiment measured data, a group of relative cutting force is calculated. The machinabilities of several common materials are discussed. For more metal materials, the data given in some book is taken advantage of to calculate the relative unit cutting force.

关 键 词：相对切削力 相对单位切削力 切削加工性 车削
