Excerpt
Abstract: This study investigates the impact of two new process technologies developed in the ATP Flow-Control Machining Project: abrasive flow-control machining (AFCM) and non-traditional combustion chamber sizing (NCCS). These new processes offer large potential benefits to manufacturers who need to increase the functional precision and performance of cast-metal machine parts. The new processes advance the state-of-the-art in the finishing of cast-metal parts that carry fluids in interior passageways. Currently, these parts often have manufacturing imperfections which decrease their precision and therefore functional performance. Finishing processes exist which correct these imperfections, but they are time consuming and costly, relegating their use to high-value, low-volume production applications. The goal of the Flow-Control Machining (FCM) Project, a joint venture between Ford, GM, Extrude Hone, University of Nebraska at Lincoln, University of Pittsburgh, and the ATP, is to develop two new automated and cost-effective finishing processes which- by smoothing, sizing, and balancing passageways- markedly improve the performance of cast-metal parts. This collaborative project is on track toward completing its goals; when successful, the new processes will have potentially wide application in automobile, aircraft, diesel-injector, and other manufacturing industries.
