Manufacturing Cost Modeling of Castings Produced with CRIMSON Process

Abstract

The present paper uses the analytical cost estimation technique to estimate the variable cost of the CRIMSON process. In order to assess the performance of the CRIMSON process, the analytically estimated cost is compared with the conventional sand casting process cost. Because of the difficulty of data collection for analytical cost estimation, discrete event simulation method is employed to assist time based data collection. In order to cope with various input of the casting process, a comprehensive cost estimation tool was also developed to assist the cost estimation. It was found that the most expensive variable cost is the raw material cost, which can be 80% of the total variable cost. Furthermore, it is concluded that the CRIMSON process has less variable cost compared with the conventional sand casting process under most of the circumstances.
