Abstract: 

Formability, it is the capacity of a material to be formed into a particular shape without failure, it is an important property of sheet metals to create complex sheet parts effectively. Prediction of Formability, Thickness distribution in deep drawing process will decrease the production cost and time of material to be formed. In this study, Experimental analysis is using to draw cylindrical cups at elevated temperatures i.e. Room temperature (32°C), 150°C, 300°C and with different thickness of blanks i.e. 1mm, 1.5mm, 2mm with 105mmm dia, 110 mm dia. Influence of forming temperature on maximum drawing load is measured. Influence of forming temperature on thickness strain, Influence of forming temperature on radial strain, Influence of forming temperature on Hoop strain were tabulated and experimentally analysed. Experimentally thickness distribution at various locations in half cut cup along with flange region is identified. Forming limit curves are plotted based on the experimental results predicted safe zone for sheet metal for different thickness of blanks.
