Deep Drawing is one of the affordable and effective sheet metal manufacturing methods in which the sheet metal is drawn radially on a shaping apparatus using the strain obtained from the punch force given to the sheet. This kind of manufacturing process is obtained from the punch force given to the sheet. This kind of manufacturing process is obtained by metal conversion process through material retention and is achieved by tracing the part through a series of drawings. During this process, the coefficient of friction affects product quality and tool life. Moreover, thermal stresses will also be created due to the change in temperature of the metal. These thermal shocks are due to the rapid change in temperature, which leads to the development of cracks and shattering during the deep drawing. To avoid these defects, lubricants of suitable viscosity are used to reduce the coefficient friction. An FE analysis was conducted to understand the forming process. A few parameters like pressure applied due to coefficient of friction & thermal-induced stress were noted by changing them, where the blank holder force and punch force were kept constant. The obtained values in the FE analysis have been compared with the values obtained in the mechanical calculations and experimentation.
