Abstract--This study focuses on the deep drawing process of IS 513 CR 4 sheets, both experimentally and through finite element analysis. IS 513 CR 4 sheets are widely used in industries like automotive and appliances due to their smooth surface, good strength, and excellent formability. In this experiment, 1.2 mm thick IS 513 CR 4 sheets were used, with circular blanks of 105 mm, 107 mm and 109 mm, in diameter. The deep drawing process was carried out at room temperature using a 30-ton hydraulic deep drawing machine. Force-displacement curves for each blank were recorded using integrated software. Formability was assessed using the Limiting Drawing Ratio (LDR), which is the ratio of the maximum blank diameter to the punch diameter. A higher LDR indicates better formability. Additionally, 3D finite element models were developed to simulate the deep drawing process. The experimental and simulation results showed good agreement, confirming the accuracy of the analysis.
