Deep Drawing is the forming process where the shape of the punch is projected to the blank by the application of force with the help of a die and blank holder. Obtaining a quality product in the deep drawing process mainly depends on the characteristics of blank materials. The deep drawing process influences the process parameters like blank holder force, coefficient of friction for the lubricants, etc. The deep drawing process was conducted using a hydraulic press machine with a maximum capacity of 50 Newton for blank materials like cold roll steel, stainless steel, aluminum alloys, and tungsten. The blank force required for the deep drawing process was investigated on various materials and analysed with the material properties. The Finite Element method is used to check the quality of the deep drawing product by applying various forces obtained in the experimental methods. Shear Stress and Strain obtained in the product during the deep drawing process were studied and verified with the analytical stress and strain. It was found that ductile material yields a very good drawing ratio whereas brittle material such as Titanium has very little drawing ratio which could be further enhanced by the combination of reinforcement or a mixture of allied metals
