Abstract

Design for manufacture and assembly (DFMA) guidelines reduce the part count, the number of welds, and the number of operations. This reduces labor costs by achieving a shorter assembly time, decreases start-up costs by eliminating the need for several operations, and reduces material costs by eliminating parts. Design for Manufacture and Assembly (DFMA) technique has been utilized extensively in industry field these days. This paper is a detailed review which will discuss the application on DFMA. Using Boothroyd and Dewhurst Method, it employs a quantitative analysis of the design. Each part of the design is rated with a numeric value depending on its manufacturability. The numbers are summed for the entire design and the resulting value is used as a guide to the overall quality of the design. The product is then redesigned, using the numerical values as a goal to be minimized. This again, however, requires much insight and knowledge on the part of the designer. This DFMA tool not only will perform a reverse engineering product and process analysis, but also help the user to explore alternative solutions.
