may be applied to any location on any of the punches and dies in fig1 a 17 b 17 c and 17 d essentially all of the cryogenic fluid i e at least 90 of each cryogenic fluid and corresponding jet in fig1 a 17 b 17 c and 17 d may impinge on the respective punch or die the use of the cryogenic fluid may cool each punch and die to a respective geometric average temperature that is less than the geometric average temperature of the final formed workpiece another embodiment of the invention is illustrated in fig1 for drop hammer forming in this process a workpiece not shown is placed between punch 1801 and die 1802 and the punch is lowered to press against the workpiece and the die one or more times thereby forming the workpiece to yield a final formed article this power drop hammer may be powered by compressed air in cylinder 1803 which moves piston 1804 connecting rod 1805 and ram 1806 to lower punch 1801 cryogenic fluid may be applied to either or both of the punch and the die fig1 illustrates the application of cryogenic fluid 1807 via spray feed line and nozzle 1808 to form jet 1809 that impinges on punch 1801 thereby.
