摘　　要：介绍镗削加工的力学模型。沿切削刃切屑厚度的分布,被作为刀具刃倾角、刀尖圆弧半径、切削深度和进给量的函数被建模。使用机械的和直角到斜角切削转变两种方法,建立该过程的切削力学模型。Machanices of boring operations are presented in the paper. The distribution of chip thickness along the cutting edge is modeled as a function of tool inclination angle, nose radius, depth of cut and feed rate. The cutting mechanics of the process is modeled using both mechanistic and orthogonal to oblique cutting transformation approaches.

关 键 词：力建模 切屑负荷 单刃镗削 直角到斜角转变
