Lower manufacturing costs and shorter time to market are possible if casting suppliers can design tooling and respond to design changes quickly enough to be part of a concurrent engineering ream. One software tool that permits suppliers to react quickly to design changes uses a parametric, feature based, associative structure that comprises the total product definition. In such software, the product model exists only once, and all operations performed throughout the supply chain merely point to that model. As a result, updating manufacturing deliverables and process plans is automatic, quick and error-free.
