Design of on-line inspection methodology for reduction of cost of internal failure - A case study in sheet metal industry

P. V. Kane, V. S. Deshpande

Abstract

Industries can endure the superiority over competitors by obtaining proper tradeoff between the quality and cost. One of the alternatives is to reduce the cost of quality. A small-scale unit (SS) in central India engaged in sheet metal working operations has been identified as a potential area for reduction in quality cost. The cost of internal failure has critically analyzed and reduced by eliminating its prominent causes. The critical and frequently occurring defects are targeted for identification at the respective stages of manufacturing process. Accordingly gauges are designed for identification of location error and camber. Inspection by online gauge was incorporated between the straightening decoiler machine and first cropping operation. Since the further processing of defectives is eliminated the cost of internal failures is reduced by about 40%.
