摘要： A METHOD OF FORMING AN IRREGULAR SHAPED CAVITY IN A METALLIC MEMBER INCLUDES THE STEPS OF DRILLING A HOLE IN THE MEMBER. A RELATIVELY LARGE PUNCH IS THEN INSERTED INTO THE DRILLED HOLE TO EXPAND THE HOLE WHILE THE METAL MEMBER IS SUBJECTED TO HEAT. AFTER THE MEMBER IS COOLED, A SECOND PUNCH, CONFORMING IN SIZE AND SHAPE TO THE CAVITY TO BE FORMED, IS INSERTED INTO THE EXPANDED HOLE. THE MEMBER IS THEN COMPRESSED AROUND THE SECOND PUNCH TO CAUSE THE HOLE TO CONFORM TO THE SIZE AND SHAPE OF THE SECOND PUNCH.
