Forming Cutter Design System Based on Function Decomposition and Parametrization

分析了成形刀具的设计特点 ,以产品设计功能分解图表达基于功能分解的产品特征 .运用参数化技术 ,对各功能特征实现参数化驱动 ,建立基于特征的参数化图形库 .然后按照功能分解的反方向对各几何体素进行拼合完成刀具的造型过程 ,从而大大提高了成形刀具的设计效率和设计质量 .

Studying the design characteristics of the forming cutter, the paper presents the product characteristics based on the function decomposition with the product function diagram. An forming cutter parametric graph base is built by adopting the parameter driving technology. The moulding process of the cutter has been accomplished by fitting the geometric elements together in the opposite direction of function decomposition, which greatly improve the efficiency and quality of the design.
