Abstract: In this paper a systematic approach is proposed that evaluates the overall accuracy of a part. In this approach, by using the feature taxonomy, a part is decomposed into primitive features. Then, each feature is compared to the original CAD. Features are evaluated based on their size, form, orientation, and position. Laser scanning technique is used to collect a feature's data and its conversion into CAD data. To reduce data processing time for non-freeform features, manual digital dial indicators were customised and used for data collection. To process and evaluate the part's accuracy, statistical and CAD methods are applied. One benefit of the proposed hybrid system is that different errors can be differentiated and separated.

Keywords: feature taxonomy; forms; attributes; reverse engineering; accuracy measurement; laser scanning; component accuracy; CAD.
