Design of equipment to reduce defect in anchor plate production

Abstract

This research aimed to reduce defect in the manufacturing process: a case study of the production of anchor plate parts. The study of the anchor plate manufacturing process revealed a defect in the second step, drilling small holes, which accounted for 83.49%. Waste characteristics were then analyzed using the Pareto principle. The first defect was misaligned holes, was found to be 91.84% and the second was misaligned plates, was 5.81%. Remediation efforts were undertaken to address both problems. ECRS principles were used to identify solutions and design equipment using tool engineering principles to assist with hole positioning. After the design of the positioning device, defect was reduced from 6.22% to 0.29%.
