A methodology for systematic generation and evaluation of alternative operation plans

This chapter describes a methodology for analyzing some of the manu-facturability aspects of machined parts during the design stage of the product development cycle, so that problems related to machining can be recognized and corrected while the product is being designed. Starting with the CAD design for a proposed part, our basic approach is to systematically generate alternative operation plans for machining the part, evaluating the capabilities of each operation plan to see which one best balances the need for eecient manufacturing against the need for a quality product. We anticipate that the information provided by this analysis will be useful both to provide information to the manufacturing engineer about alternative ways in which the part might be machined, and also to give feedback to the designer about problems that might arise with the machining.
