This paper is based on the study of influence of thickness of the sheet and arc radius of fillet curve in sheet metal forming process. To avoid forming process from cracks and wrinkles optimized set of the values of thickness of sheet metal and arc radius should be obtained. Determination of the optimum value of thickness of sheet and fillet radius is very tedious process as it requires large number of numerical simulation on AutoForm-Incremental software, which takes much time and reduces efficiency of the process. To overcome this problem Fractional Factorial Designs technique is introduced. This method reduces numerical simulation by keeping only most important values of thickness and fillet arc radius. Each numerical simulation gives different result depending on the geometric factors i.e. thickness of sheet metal and fillet arc radius. Results obtained from numerical simulation using AutoForm-Incremental software are used to determine most reliable and safe model obtained at optimum value of the thickness and arc radius.
