A computer software based method for aiding and systematizing the procedure of fixture selection and allocation for workholding is proposed in this study. The method recognizes geometric features of parts from their CAD models and suggests fixture configurations that aide human operators to setup the fixture hardware based on supporting and locating fixture rules. It is further proposed that computerization of fixture planning should be combined with development of new, integrated holding devices that can be automatically configured and actuated, if the fixturing process is to be significantly automated. A recently proposed and developed device, called Dual-Dexterous-Vises, is applied as an example of such an integrated workholding system. The computer-aided workholding planning method was demonstrated by using traditional discrete fixturing elements and by applying the Dual-Dexterous-Vises system.
