This article introduces the revolutionary design of a leaf jig equipped with proximity sensors that significantly reduce the cycle time during the flange drilling process. By attaching proximity sensors to a leaf jig, it is possible to drill an array of holes on the flange. It verifies proper seating while locating the jig plate prior to drilling. Reduced cycle times are possible in the mass manufacturing of flanges by lowering the overhead time for positioning, adjusting, and inspecting. Two flow-process diagrams for drilling operations are created utilizing template and leaf jigs. According to the flow-chart analysis, the verification of flange seating using a feeler gauge is eliminated in the leaf jig, while the production rate rises by 17%.
