提出了一种新的平面铣削型腔曲线轨迹生成方法。该方法使用的椭圆型偏微分方程边值问题的解决方案上定义的口袋区域。此数学函数有助于将腔室内部的平滑低曲率螺旋路径变形为符合腔室边界的路径。正如这里描述的实验所示，这种变形导致切削硬金属时的刀具磨损和切削所有金属时的加工时间大幅减少。还描述了可变进给速率优化过程。该程序结合了路径、刀具啮合和机床约束，可用于最大限度地提高任何刀具路径的机床性能。
A novel curvilinear tool-path generation method is described for planar milling of pockets. The method uses the solution of an elliptic partial differential equation boundary value problem defined on a pocket region. This mathematical function helps morph a smooth low-curvature spiral path in a pocket interior to one that conforms to the pocket boundary. This morphing leads to substantial reductions of tool wear in cutting hard metals and of machining time in cutting all metals, as experiments described here show. A variable feed-rate optimization procedure is also described. This procedure incorporates path, tool-engagement, and machine constraints and can be applied to maximize machine performance for any tool path.
