ingle Point Incremental Forming (SPIF) process is one of the advanced forming techniques that industry has nowadays. Improved formability is one of the major advantages of the process. However, it is associated with limitation such as thinning of blank and poor geometrical accuracy of the formed part. In this study, forming behaviour of homogeneous blanks during the SPIF process has been investigated. A simulation study has been carried out using ABAQUS/Explicit. Effect of change in thickness, yield strength, strain index and strength coefficient of blank on responses like Plastic Equivalent Strain (PEEQ), percentage of thinning and geometrical accuracy of formed component has been evaluated. It has been found that change in the thickness has major effect on PEEQ and geometrical accuracy. Regarding percentage of thinning, change in the yield strength of blank is found to be majorly affecting.
