Roles of Process Parameters and Materials Properties on Galling During Blanking and Punching of Aluminum Sheets

由温莎大学和novelisresearch人员合作开展的NSERC Engage研究项目提供了一种新的有效方法，用于测量铝板剪切和冲压过程中转移到工具表面的铝量。使用这种基于白光干涉测量的方法将允许确定Al磨损率作为工艺参数的函数，例如间隙百分比，角度，压力和使用不同的润滑策略。此外，还建立了切削边缘特征（抛光和剪切断裂）与磨损量随冲压循环次数的增加之间的相关性。NSERC Engage Plus项目旨在建立在这些成就的基础上，提高我们对人工智能问题的理解。提出的研究目标包括：(1)研究间隙和润滑油的变化对磨损和修整边缘特征的影响；Ii)铝板力学性能对裁边质量影响的研究；Iii)使用碳基刀具涂层，结合适当选择润滑剂，以减轻磨损，提高刀具寿命和剪切边缘质量。

The collaborative NSERC Engage research project undertaken by the University of Windsor and Novelisresearchers resulted in providing an new and efficient method for measuring the amount of aluminumtransferred to the tool surfaces during shearing and punching of aluminum sheets. The use of this methodbased on white light interferometry will allow to determine Al galling rate as a function of processparameters, such as clearance percentage, angle, pressure and using different lubrication strategies.Furthermore a correlation was established between the cut edge features (burnish and shear fracture) and thegalling volume increase with the number of press cycles. The NSERC Engage Plus program is intended tobuild on these achievements improve our understanding of Al galling problem.The objectives of the proposed research include i) studying the effect of variation in clearance and lubricant onAl galling and trimmed edge features; ii) investigation of the influence of mechanical properties of thealuminum sheets on the trimmed edge quality; iii) use of carbon based tool coatings in conjunction with theappropriate selection of lubricants which to mitigate galling improve the tool life as well as the sheared edgequality.
