3D-CAD連携鋳造性自動チェック技術の開発

抄録

In the field of cast products, the occurrence of defects such as shrinkage and cracking is a critical concern directly associated with the complexity of design structure. To mitigate the risks associated with these defects, prior verification processes have been widely employed, encompassing casting simulations, experimental studies, and expert reviews. However, these traditional verification approaches are labor intensive and prone to process rework due to inadvertent oversight. In this study, ten design rules for castability were implemented in the “Design Insight CAD system”, an automated CAD geometry verification tool. This paper presents an evaluation of the system's capability to automatically detect potential defects in an engine cover part. The results showed that the system successfully identified parts to defects, such as insufficient wall thickness, corner without fillet and insufficient distances between holes. The automated inspection process was completed in 2 minutes, demonstrating the efficiency and effectiveness of the developed technology.
