摘　　要：建立了含非自由切削干涉参数的圆弧刃切削力公式，定义了非自由切削的非自由系数。通过对圆弧刃、分段圆弧刃、开分屑槽圆弧刃的分析和切削试验，揭示了干涉系数θ的影响及圆弧刃分段多数对降低非自由系数的作用。The cutting force is expressed by the interference parameter θ of edgeelement during chip formation. A coefficient φ is difined in order to evaluate the degree ofdeviation from free-cutting model. By the cutting test using an integrated circular edge, a groupof circular segment edge,and a circular edge with grooves for chip splitting, the effect ofinterference parameter θ and number and arc degree of segment edge on cutting force of non-freecutting is explored.
