The paper describes new developments in a feature-based process planning system. Extensions are discussed toward a framework where planning is accomplished via retrieving and adapting previous, part family-related plans. Our primary concern here are the prerequisites to the re-use of plans: the assessment of similarities of parts, and the matching of their feature-based descriptions. Contrary to the traditional approaches, we define a new notion of part similarity that is based on the morphology of the precedence graphs over the parts' feature states. Procedures that support the matching of features of different parts by relying mainly on this ordering information are given, and a running example explains how they actually work.
