A graph theoretic approach linking design dimensioning and process planning Part 2: Design heuristics for rotational parts

The purpose of this paper and its companion (Part 1) is to present a rigorous graph theoretic model to link designing with process planning. Part 1 explains how to develop process plans from design dimension trees. Part 2 explains how knowledge of the structure of datum-hierarchy trees underlying process plans can be used to formulate design heuristics for part dimensioning. The design dimension trees resulting from application of the heuristics have the fewest number of constraints on process planning and allow parts to be produced with minimal tolerance stack-ups and production costs. Several rules are presented to demonstrate the concepts and approach.
