A composite position tolerance verification algorithm is embedded in a simulation program to explore the producibility of three composite position tolerance variants for patterns of holes. The influence of some selective design and manu- facturing variables on producibility is simulated and evaluated. It is shown that design variables such as specification variant, material condition modifier and number of holes in the pattern have a significant influence on producibility. The influence of manufacturing variables such as orientation error and numerical Control path programming in the presence of axis reversal error are also simulated And discussed. Detailed graphs of these effects are presented and discussed.
