Development of a computer-aided fixture design system for lightweight grippers in the automotive industry

Article in journal (Refereegranskat)
The need for dedicated fixtures for flexible manufacturing systems is increasing, as dedicated fixtures are lighter, more compact and, more accurate than flexible fixtures. The main challenges are that parts and processes are more and more complex, which requires designing novel or complex dedicated fixtures, and that, for one given flexible fixture to be replaced, several variants of such dedicated fixtures must be designed to hold a variety of individual parts, without imposing increased costs and delays. The systematic fixture design method and computer-aided design fixture system (CAFDS) developed and applied for the presented industrial case—novel design of lightweight (carbon fibre composite) robot grippers—is a possible approach to address these issues.
