Abstract:

Hamill Manufacturing Company, Trafford Pennsylvania, won a contract to complete eight pump casings destined for use on aircraft carriers. The 4-foot-long, 4-foot-diameter casings were made of Inconel 600 alloy. The casing flange featured 24 threaded holes, 2.375 inches wide by 5.75 inches deep. Drilling and tapping Inconel, a tough nickel-based material with high tensile strength, is time-consuming and requires high torque. Hamill determined the need to optimize the process to control manufacturing costs, and asked the National Center for Defense Manufacturing and Machining NCDMM for assistance.
