Geometric Variations: Analysis, Optimization and Control

摘要

This paper is concerned with the design and manufacturing of 2D and 3D components in the context of process modeling and inspection. A methodology is proposed that models manufacturing processes and learns shape deformations that are the result of out-of-tolerance components. Then during inspection, a deformed shape is analyzed and the process parameter values determined. The key aspect of this approach is that the mapping between process parameters and shape is determined which is not possible using standard process modeling approaches such as finite element analysis. This is different to the traditional approach to tolerancing which is very much as additional procedure to design and doesn't consider process parameter variation, just shape variation. A review of tolerancing is presented as well as a description of techniques for process modeling.
