Abstract

Single point incremental forming (SPIF) is an emerging sheet metal forming process which is used to build a prototype of sheet metal parts with complex geometries. Geometrical inaccuracies of the formed parts are the significant obstruction in the commercialisation of this process. In this paper, Taguchi method and analysis of variance have been used to comprehensively study the effect of four process parameters such as step depth, tool diameter, spindle speed and feed rate on the geometrical error in the form of average radial error of the formed part. Parametric analysis and formulation of an empirical model for predicting the amount of geometric error in this process have been discussed. From the Taguchi method and analysis of variance, the optimal results are identified adequately and proficiently to produce a minimum geometric error.
