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 permits combining several manufacturing operations 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.
