Development of Robust Optimization Procedure for Casting Conditions

Abstract

  Nowadays, numerical simulation of casting processes is widely used to optimize casting designs and conditions at various casting companies. However, it is impossible to control all the process parameters strictly, resulting in casting defects in some cases because the casting conditions are not those chosen by simulation. This paper proposes the Taguchi method based on solidification simulation as a method for selecting robust designs according to the manufacturing scene and confirms the effectiveness of the method.
