A new formability indicator in single point incremental forming

Material properties play an important role in determining the sheet fracture in metal forming processes. However, the degree of influence of a material property on the forming extent depends on the nature of the forming process employed. In the current study, the effect of various material properties on the formability in SPIF has been investigated. Correlations of the formability with material properties under investigation were developed in order to establish a new formability indicator. An empirical model describing the effect of the newly introduced formability indicator has also been proposed.
