RESEARCH AND DEVELOPMENT OF TITANIUM ROCKET MOTOR CASE. VOLUME 2. RING ROLLING AND FLOWTURNING CYLINDRICAL SECTIONS

Abstract

A major improvement in flow-turning technique was developed with subscale parts. The effects of roller geometry, mandrel speed, wall thickness reduction per pass, and roller-feed rate on radial growth and local bulging were determined. It was found that roller geometry had the most predominant effect on dimensional control and a new roller design with parabolic contours was developed which gave positive control of diametral growth. A correlation of flow-turning parameters was developed which permitted techniques developed with subscale cylinders to be directly applied to full scale parts. The resulting full scale flow-turned cylinders had very little diametral growth and no local bulging.
