摘要/Abstract

摘要： 针对正交车铣加工变深度、变厚度的切削特性，基于其加工原理采用数学方法建立切削力的理论模型，并在无偏心和偏心二种情况下分别仿真圆周刃和端面刃的切削力随铣刀转角的变化规律。通过切削参数对切削力影响规律的仿真结果分析表明，圆周刃在整个切削过程中起到主导作用；在相同切削参数条件下，随着进给量和偏心距的增大，切削力增大，而偏心切削力大于无偏心切削力。因此该切削力的理论模型为正交车铣加工机理的研究提供理论基础和参考依据。

Abstract: Aimed at the characteristics of variable cutting depth and thickness in the orthogonal turn-milling process, the theoretical model of cutting force is founded by using mathematic method based on the machining principle, and the change rules of cutting forces with the rotation angles of cutter were simulated in the conditions with and without eccentricity, respectively. The simulation results show that, with the increase of feed rate and eccentricity, the cutting force increases in the same cutting parameters and it is bigger in eccentricity than that in non-eccentricity. Therefore, the theoretical cutting force model provides reference for the research on orthogonal turn-milling mechanism.
