Comparison of Major Forging Systems.

Abstract : A program to compare equipment effectiveness in providing superior structural forgins of advanced aerospace materials was completed. Comparisons of precision, quality, properties, and costs were made from structural forgins produced to common shapes with different equipment. The program was divided into separate efforts involving intermediate size and large forgings. In general, hammers and hydraulic presses are both cost effective in forging structurals to the variety of shapes, sizes, and materials in the quantity requirements typical of aerospace applications. Mechanical presses and HERF machines are limited in application to structurals because of limited variability in die closure characteristics. (Author)
