Study on the Parameterized Characteristic Moulding Technology for CAD of Injection Moulds

参数化特征造型技术是通过规划或代数方程的形式定义尺寸或要素之间的约束关系 ,实现对已建模型的动态修改 ,可大大提高注射模设计的自动化程度。作为解决CAD/CAE/CAM接口问题的特征造型技术 ,将参数化思想和方法吸收进来 ,并有机结合 ,产生了先进的参数化特征造型方法 ,成为现代注射模CAD领域的重要研究方向。

The parameterized characteristic moulding technology defines the constraint relation between dimensions or elements through programming or algebraic equations, to realize dynamic modifications on the built models. It can greatly increase the automatization degree for the design of injection moulds. As a solution to the CAD/CAE/CAM interface problem, the characteristic moulding technology absorbed the parameterized concept and method. And by combining the two, the advanced parameterized characteristic moulding technology was brought into being and became the important research direction in the CAD field of injection moulds.
