9410093 DeMeter The award is for research to develop better understanding of workpiece deflections due to clamping forces resulting from part fixturing systems during machining operations and the resulting part geometric errors. Such improved understanding will help design fixturing systems which minimize part geometric error in the presence of cutting forces. The concept of approximate models or meta-models is used to simplify the problem solution. The results of the research would benefit machining fixture design practices and would be applicable to a broader class of contact problems in mechanics characterized by variable boundary conditions. Currently, the area of machining fixture design is not being addressed adequately by research despite its acknowledged importance.

小行星9410093 该奖项是为了更好地了解工件变形的研究，这些变形是由于加工操作过程中零件夹具系统产生的夹紧力以及由此产生的零件几何误差造成的。 这种改进的理解将有助于设计夹具系统，最大限度地减少零件的几何误差，在切削力的存在。 近似模型或元模型的概念被用来简化问题的解决方案。 研究结果将有利于加工夹具的设计实践，并将适用于更广泛的一类接触问题的力学特征是可变的边界条件。 目前，加工夹具设计领域没有得到充分的研究，尽管其公认的重要性。
