Integrated Strength and Manufacturing Process Design Using a Shape Optimization Approach

This paper considers a simultaneous design of product and manufacturing process. The product requirements include strength properties, whereas the manufacturing process goals include cost, quality, and microstructure to produce defect-free parts on a repeatable basis. The concept is demonstrated by designing a turbine disk manufactured using a forging process. A simplified analysis is used in forging process simulation. Formulation of the integrated design problem is emphasized.
