This paper describes ongoing research in cost estimation for net-shape manufactured components. Net-shape manufacturing (NSM) processes such as die casting, injection molding, stamping, and forging are different from machining operations in the sequence of creating component features. These processes are used to produce all features of a component in one shot. Therefore, the cost estimating approaches used in machining operations based on the process plans are not appropriate for NSM. In this paper, we describe how to obtain a database of historical components together with their geometric complexities and estimated costs. Also, we describe representing, indexing, and retrieval of similar components in this database. Component representation is based on the data extracted from its STEP file.
