Effect of tooling geometry on the cutting surface of punched aluminium slugs

铝锭是半成品，通常以金属盘的形式，用于生产各种用品，如气雾剂罐和机动车部件。Ball technologies d 'Aluminium Avancées Canada通过冲压内部铸造和轧制的金属条来生产毛坯。他们一直难以生产具有大厚度直径比（t/d）的段塞。对于接近1/1的比率，在坯料的外径上存在缺陷，使得它们不适合进一步加工。为了了解模具参数如何影响缺陷的发生，将对使用2套不同模具制成的毛坯进行微观结构表征，并进行工艺模拟。模型将使用拉伸和剪切试验结果进行校准，并通过实验进行验证。然后，他们将被用来研究的影响，模具参数上的质量的毛坯。

Aluminium slugs are semi-finished products, often in the form of metal disks, that are used to produce various supplies like aerosol cans and components for motor vehicles. Ball technologies d'Aluminium Avancées Canada produce slugs by punching metal strips that are cast and rolled in-house. They have been having difficulties with the production of slugs with a large thickness to diameter ratio (t/d). For ratios approaching 1/1, defects are present on the outer diameter of the slugs, making them inappropriate for further processing. In an effort to understand how the tooling parameters influence the occurrence of defects, microstructural characterization of slugs made with 2 different sets of tooling will be done, and simulations of the process will be performed. The models will be calibrated using tensile and shear tests results, and validated with experiments. They will then be used to study the influence of the tooling parameters on the quality of the slugs.
