Abstract : A design evaluation study was conducted to establish requisites for tool design. Design criteria were formulated and operating parameters were delineated. Clamping, and driving forces, milling cutter loads, tracking, and driving power requirements were established. A basic design concept for a basic tool carriage incorporating interchangeable cutting and welding heads was subsequently established. Welding studies were conducted to determine the effect of arc voltage, gap, electrode configuration, and shield gas on the weld bead. Three commerical electrical power supplies, and related equipment, were used in condcting tests to determine equipment adaptability and performance under different operating conditions. Material studies were conducted to selected candidate materials typical of advanced liquid rocket systems, for use in tests. The candidate materials include aluminum, titanium, nickel- and iron-base alloys. (Author)
