This paper presents a framework for an analysis method and computational tool, which evaluates the fabrication parameters of complex geometries. The suggested method predicts the feasibility, material use, and machining time required for fabricating the moulds for these geometries. It achieves this by interrogating geometric properties instead of the traditional machining simulations. Using the algorithms developed in this research, the method can provide real time evaluation of computer-controlled mould fabrication techniques such as cutting and assembling sheet materials, multi-axis milling of volumetric material, and robotic hot wire cutting. In the paper, we describe the mathematical basis of the suggested method. We demonstrate how the method provides real-time visual feedback for designers and allows them to adjust their design according to fabrication constraints in the early design stages. Using architectural case studies, we show how the analysis results provide precise cost estimates and help minimize fabrication resources in manual or automatic fabrication optimization processes.

本文提出了一种分析方法和计算工具的框架，用于评估复杂几何形状的制造参数。建议的方法预测了为这些几何形状制造模具所需的可行性、材料使用和加工时间。它通过询问几何特性而不是传统的加工模拟来实现这一点。使用本研究中开发的算法，该方法可以对计算机控制的模具制造技术进行实时评估，例如切割和组装板材、体积材料的多轴铣削和机器人热线切割。在本文中，我们描述了建议方法的数学基础。我们演示了该方法如何为设计师提供实时视觉反馈，并允许他们根据早期设计阶段的制造限制调整设计。通过建筑案例研究，我们展示了分析结果如何提供精确的成本估算，并帮助最大限度地减少手动或自动制造优化过程中的制造资源。
