Abstract : The sheet metal forming parameters of the Model J Androform machine were established for .010, .040, .080, and .125-in.-thick materials in various heat treated conditions of Al stainless steel, and Ti. Nomographs were derived for determining the longitudinal and transverse contour combinations which are within the Androform machine forming limits. Mechanicl property tests were conducted on the .040 alloys, all of which were formed to maximum contour. Results showed a general increase in tensile and compressive yield values with a loss in per cent elongation. The titanium materials, RS-140 and 4Al-3Mo-1V in the solution treated and solution treated and aged conditions, were exceptions. The compressive yield strengths of these materials decreased.
