摘要
在曲面铣削过程中,由于工件外形复杂,刀具位姿多变,使球头铣刀铣削力模型的建立较为困难。本文在考虑工件表面几何特征和刀具位姿变化的基础上,通过解析法确定了刀-工切削接触区域的边界条件,利用空间坐标旋转变换得到了适用于复杂曲面加工的五轴球头铣刀铣削力模型,对铣削力模型进行仿真并通过试验验证了模型的有效性。
In the process of sculptured surface milling,it is difficult to establish the milling force model of the ball-end milling cutter due to the complex shape of the workpiece and the changeable position of the tool.In this paper,the boundary conditions of the cutter-workpiece cutting contact area are determined analytically based on the consideration of the geometrical characteristics of the workpiece surface and the change of the tool posture.Using the spatial coordinate rotation transformation method,a milling force model of a five-axis ball end milling cutter suitable for complex surface machining is obtained,the milling force model is simulated and the validity of the model is verified through experiments.
