针对传统刀位轨迹生成方法存在的刀具轨迹沿着存在高曲率区域等问题，提出了一种基于水平集的刀位轨迹生成方法。口袋边界首先嵌入到一个高维函数，即水平集函数。然后，刀具路径实现的口袋边界的传播。刀具轨迹的拓扑变化可以在运动前沿的演化过程中自然地处理。为了避免沿着刀具轨迹出现高曲率角点，采用曲率相关项来调节水平集方程的速度函数。同时，利用曲率流运动来识别型腔的可加工区域。向量水平集函数用于处理具有多个岛的复杂口袋。讨论了基于隐式描述的材料去除率模拟方法。通过数值算例验证了该方法对不同类型岛屿口袋的鲁棒性。
With the increasing application of high speed machining for pockets, the conventional methods of tool path generation show their limitations, such as the existence of a high curvature region along the tool path. This paper presents a level set approach of tool path generation for high speed machining of pockets. Pocket boundary is first embedded into a higher dimensional function, namely, the level set function. Then the tool paths are realised by the propagation of the pocket boundary. The topological changes of tool path can be naturally handled during the evolution of moving fronts. In order to avoid the appearance of high curvature corners along tool paths, a curvature-dependent term is adopted to regulate the velocity function of the level set equation. At the same time, the curvature flow motion is used to identify the machinable region of pockets. The vector level-set functions are utilised to handle complex pockets with multiple islands. The simulation of material removal rate based on the implicit description is also discussed. Numerical examples are presented to demonstrate the robustness of the proposed approach on different kinds of pockets with islands.
