A shape metric for design-for-assembly

The authors introduce a quantitative shape metric for planar parts, called feedability, based on a stochastic parts feeding algorithm reported by K. Goldberg et al., (1990,1991). Although feedability is only one possible metric for design-for-assembly (DFA), it relates one aspect of assembly cost directly to part geometry. Therefore, based on feedability, a set of geometric redesign strategies can be produced. The application of feedability to DFA is illustrated and compared with other DFA methods.<<ETX>>
