Development of design rules for automatically check manufacturability and maintainability in Design Insights CAD system.

Abstract

We are developing “Design Insights CAD” system that automatically checks the design rules on 3D-CAD and show the violation parts to prevent rework from manufacture and maintenance to design. This system has the following functions: 1) Shape recognition functions to search the target shape from 3D-CAD models, 2) Calculation functions to measure geometric features such as dimensions and angles. We combine these functions to generate digitalized rules that can be applied to a wide variety of design rules. This report describes the development of rules to evaluate the manufacturability of welding and casting and the results of their verification.
