Evaluation of Process Parameters of Conical Cups in Incremental Deep Drawing Process

The aim of the present work was to evaluate the effect process parameters of conical cups made of AA7075 alloy in incremental deep drawing process. The design procedure for the finite element analysis was carried out as per Taguchis techniques using ABAQUS software code. The friction coefficientof incremental deep drawing was the critical process parameter influencing the effective stress induced during the formationofconical cups. von Mises stresses induced in the cups are within thelimit of ultimate strength of AA7075. The sheet thickness hadinfluenced the reduction of sheet thickness during the cup formation to the extent of 83.78 %.
