Deep Drawing is the forming process where the shape of the punch is projected to the blank by the application of force withthe help of a die and blank holder. Obtaining a quality product in the deep drawing process mainly depends on thecharacteristics 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 witha maximum capacity of 50 Newton for blank materials like cold roll steel, stainless steel, aluminum alloys, and tungsten. Theblank force required for the deep drawing process was investigated on various materials and analysed with the materialproperties. The Finite Element method is used to check the quality of the deep drawing product by applying various forcesobtained in the experimental methods. Shear Stress and Strain obtained in the product during the deep drawing process werestudied and verified with the analytical stress and strain. It was found that ductile material yields a very good drawing ratiowhereas brittle material such as Titanium has very little drawing ratio which could be further enhanced by the combinationof reinforcement or a mixture of allied metals.
