本文提出了一种用于多轴复杂曲面加工的最优刀具轨迹生成方法-扫掠包络法。分析了扫描包络的性质。研究结果有助于我们认识刀尖加工的几何匹配和刀侧加工的几何可加工性。根据周围障碍物的存在情况，将目标曲面分为开边界雕塑曲面和闭边界口袋曲面。开放边界雕塑表面加工的目标是最大化用于刀尖加工的圆角端刀具的加工带宽度，从而优化加工效率。另一方面，封闭边界型腔加工的目标是使球头刀具的刀具轴线平滑，以用于刀具尖端和刀具侧加工，从而优化刀具路径变化。扫描包络的补充，这代表了在过程中的工件，也解决了。最后对所开发的技术进行了演示，并给出了应用实例。
This paper presents swept envelope techniques to generate optimal tool paths for multiple-axis sculptured surface machining. The properties of the swept envelopes are analysed. The results help us to realise the geometric matching in tool-tip machining and understand the geometric machinability in tool-side machining. The target surfaces are classified into open-boundary sculptured surfaces and closed-boundary pocket surfaces, based on the existence of the surrounding obstacles. The objective of the open-boundary sculptured surface machining is to maximise the machining strip width of the fillet-end tools for tool-tip machining and, thus, to optimise the machining efficiency. On the other hand, the goal of the closed-boundary pocket machining is to smooth the tool axes of the ball-end tools for both tool-tip and tool-side machining and, therefore, to optimise the tool path variation. The complement of the swept envelope, which represents the in-process workpiece, is also addressed. It finally demonstrates the developed techniques and illustrates the application examples.
