Abstract
The success or failure of a deep-drawing operation is strongly dependent on the selected lubrication. Lubricants are traditionally formulated from mineral oils that are harmful to workers’ health and of difficult discard. The potential of vegetable oils as lubricants, in deep-drawing processes, is already proven by recent studies. However, it is needed to investigate solid additives that can complement the properties of these oils. The deep drawing of composite materials has high applicability for the industry and can provide multifunctional needs that may not be found in conventional steel sheets. The present work is an experimental analysis of vegetable oils with silica microparticles performance, applied in the deep drawing of a layered sheet composite in a sandwich arrangement. Castor, cotton, and canola oils were used as the base fluids. Two samples of silica with two different particle sizes and three different concentrations were used as solid additives. A cup with an internal diameter of 22 mm and a height of 10 mm was the final product obtained from the deep-drawing process. The effect of lubrication on the process was analyzed by ANOVA, investigating the maximum stamping force. The maximum deep drawing forces corresponded to previous studies and were only influenced by the different types of silica.
