Effect of process parameters and preheating temperature on surface roughness and thickness distribution in hole flanging using Incremental Sheet metal Forming

Abstract

Incremental Sheet metal forming is a die less method of forming which offers high formability. In this research work; effect of step depth, tool rotation speed and preheating temperature on surface roughness and thinning of flange wall is investigated in hole flanging using incremental forming. The parameter optimization is carried out by Taguchi method. Grey relational analysis is carried out to obtain best parameter combination.
