Abstract: Compound die is a press tool of collective operations performed on the sheet metal. The various operations are carried out in a single stroke. The design of compound die is largely depends on material of sheet metal, thickness of sheet metal and complexity of design and operations. This press tool has significance like high rate of production and minimum per unit cost of product. In compound die the variety of operations are performed at common work station. In present thesis the intensions is given on quality improvement along with production rate. Some drawbacks like spring back effect can be compensated in designing of compound die.

Keywords: Compound die, spring back effect, complexity of design, rate of production.
