CVN-21 Carrier Casing

Abstract

The part in question was a pump-housing made of 304 Stainless Steel weighing 37,000 lbs., and taking approximately 1400-1500 hours to machine. To be awarded the contract for 4 housings, pricing had to be competitive. Creative machining methods had to be developed and utilized. One problem area was an operation to cut 24 4.25-inch threaded holes 10 inches deep. Other advanced machining methods and techniques were required to reduce the total machining time of the entire component. The National Center for Defense Manufacturing and Machining (NCDMM) was requested to review current processes against current manufacturing technologies and recommend tooling and process changes.
