FORCOD: A coding and classification system for formed parts

Abstract Part coding and classification systems are required to apply the group technology philosophy. Thus far, most coding and classification systems are for metal removal processes. This paper proposes a coding and classification scheme for the metal forming process. Coding details based on part geometry, tolerance level, surface finish, material, heat treatment, and defect level are defined. As an example, based on the proposed coding scheme, a multi-objective cluster analysis problem is formulated and solved for bosses and connecting rods, which are typical examples of forged parts.
