In this paper, theDMADV (Define-Measure-Analyze-Design-Verify) methodology has been applied toan industrial process. The considered application involves cutting tubes topredefined lengths in order to be supplied to custom-made automotive exhaust tubemanufacturers. Investigating the process reveals several problems that adverselyaffect the production. Accordingly, customer requirements have been identified andthe Quality Function Deployment (QFD) has been implemented to translate theserequirements into technical characteristics. A conceptual design of a compoundmechanism for both feeding and cutting has been suggested to overcome thedrawbacks in the current practice. A detailed 3D CAD model has been developed, inaddition to a prototype that has been manufactured to test the validity of theproposed design. Pilot runs of the prototype reveal that the developed mechanismnot only performs its intended task adequately, but also the chances of cutting wrongtube lengths have been eliminated.
