ABSTRACT:
Capitalizing on the unique feature of our induction heating workcell that permits rapid and controlled heating and cooling of a workpiece within a wide temperature range allows us to combine manufacturing into a single heating cycle to save time, energy, capital, touch labor, and factory space. For example, we can combine superplastic forming (SPF) with annealing two operations that occur at temperatures that differ by about 150-200.degree. F. (85-105.degree. C.) or more, to produce quality parts. We mill parts flat to simplify their machining, form them to complex curvature, and anneal them.
