Design For Assembly

Design-for-assembly (DFA) and design-for-manufacture (DFM) techniques can be applied to products assembled manually or automatically or manufactured by specific techniques, such as machining, die casting or injection molding. Research at the University of Massachusetts, University of Rhode Island, and by industry has been a source of information, spreadsheets, and software for those interested in DFA and DFM techniques. Design-for-assembly analysis will
