Mould Parts Design Based on Knowledge Fusion of NX

摘要

In traditional CAD technology, it is mainly to express the geometric information of parts, but can not express non-geometric information, such as weight, strength, and can not do the design of geometric distortion for changed topology. The combination of knowledge-based engineering (KBE) and CAD solved these problem in the filed of molding. NX/KF is a new technology to integrate CAD and KBE. This paper develops the mould parts with NX/KF as an example to explain its application. It analyzes the substance of parametric design and point out the developing direction of CAD by analyzing new characteristics of knowledge fusion.
