Abstract: A common problem that can plague metal castings is microporosity. This is defined as miniature, sub surface pores that can become exposed and magnified during machining and paint applications. A previously developed virtual casting process design (VCPD) strategy has been implemented to understand and improve scrap levels of visible microporosity in machine face wheels. This paper desrcibes the application of VCPD to microporosity in wheels and quantities some important sensitivities of this defect to process variables such as solidification and metal quality. The success of this investigation exemplifies the significant potential for improvement in casting and plant performance, using a systematic virtual casting process design strategy.
