Modeling and Analysis of the Effect of Preloaded Pressing Force on Gap Formation during the Drilling of Double-Layered Material

Abstract:

The drilling of multi-layered structural members has been a crucial process in aeronautic manufacturing. The burr formation on layer surfaces, especially on inter-layer surfaces, causes extra amount of deburring operations which waste time and cost. The inter-layer burr formation depends greatly on the size of the inter-layer gap which results from different deformations of the upper layers and the lower layers during a drilling process. Based on the theory of plates and shells, this paper discusses the drilling process of two stacked circular Al-2024T3 plates with edges built-in. The dependence of the inter layer gap formation on the pressing parameters and the axial drilling force is also discussed in this report.
