Influence of Single Point Incremental Forming Parameters on 1008-AISI Surface Hardness

Abstract

This paper is aimed to study the effect of some important factors (incremental step size, product angle and tool rotational speed) on the surface hardness during single point incremental forming (SPIF) of truncated cone made from (1008-AISI) workpiece. In this study the Box-Behnken design of experiment has been used. The obtained results illustrate that the incremental step size has the great significant on surface hardness among the other factors. The contribution percent of (incremental step size, rotational speed and wall angle) on surface hardness were (42.5, 12.5 and 18.13) % respectively.
