Nakagawa l japan received on march 4 1987 accepted by the editorial committee 5 i i l 1 the sheet metal forming method with hydraulic counter pressure which makes use of hydraulic counter pressure generated through the penetration of the punch into the die cavity. This prepares the data for the second calculation.

The follow web pages contain engineering design calculators that will determine the amount of deflection and stress a flat plate of known thickness will deflect under the specified load and distribution. To get an accurate calculation you must convert all of the values to the same unit of measurement inches pounds and tons. First the sheet metal pat draw on autocad screen as shown in figure 2. Centrifugal casting is both gravity and pressure independent since it creates its own force feed using a temporary sand mold held in a spinning chamber.
