CAD tools for knowledge based part design and assembly versioning

摘要

Increasing the efficiency of production processes is crucial in the modern manufacturing industry. This paper presents two software tools to enhance the productivity of common part/assembly design process. Both are developed for the widely used Siemens NX CAD system. The first module is an interactive multi-component software tool, which was developed for supporting similarity-based product design. This application can use product repository, makes possible to search by any specific parameters and export a new parameter file for creating new parts. The second module offers a UI driven semi-automatic way to enhance component replacement process of a complex assembly. The presented modules make the whole development process more effective because they are suitable to semi-automate the 3D model creation process. Applying these, human errors can be reduced, and the modelling process can be significantly accelerated.
