Comparison between aluminum alloys behavior in incremental sheet metal forming process of frustum pyramid shaped parts

摘要

Abstract Single point incremental forming is a new emerging technology, used mainly for prototype development or small series production, with good prospects in industrial implementation. However, the parts manufactured through this process often presents low accuracy, thus the industrial implementation is yet limited. Incremental forming process can be done with the help of different technological equipment, such as industrial robots and numerically controlled machines. Since the process is still in development phase, it is a good practice to use finite element analysis software packages in order to reduce time and costs to produce accurate parts. The aim of this paper is to investigate the behavior of different aluminum alloys deformed through SPIF regarding forming forces, thickness distribution and springback effect. Based on numerical simulations performed, the material which produces the most accurate parts for the frustum cone can be chosen for further experimental research.
