<br/><br/> Deep drawing defects such as thinning and earing present challenges to sheet metal forming industry while designers tend to favor the usage of new materials and production processes. the present work introduces an integrated approach using design of experiment approach, FEA experimentation and response surface methodology (RSM) to develop linear regression equation that is capable of predicting earing and thinning defects in deep drawing of non-circular parts (rectangular and elliptical) and determine the optimum process parameters which lead to minimum defects
