Early Cost Estimate of Product during Design Stage Using Design for Manufacturing and Assembly (DFMA) Principles

Abstract

Application of Design for Manufacturing (DFM) and Design for Assembly (DFA) methodologies can be beneficial to industries involved in the design and development of products. Improper design decisions are responsible for higher manufacturing cost for a product. Thus it is important to include DFMA by combining principles of both DFM and DFA principle early in the design process. This paper presents a case study of manufacture and assembly costs estimation during the design phase of washing machine and which is to be manufactured in company located in India, and intends to make this economically feasible. Solidworks and Solidview software tool were used to generate CAD models which were further analysed using DFMA software tool. The result obtained was accepted by industry and match with the market value of washing machine.
