Analysis of formability and twist angle in AA5052 alloy by single point incremental forming process

Abstract

The incremental forming process is highly characterized by its degree of flexibility and mainly suggested for rapid prototyping. Formability of the sheet metal mainly depends on the properties of the metal sheet, forming process and forming conditions. This paper focuses on the development of FLD for AA5052 alloy at room temperature. In this study a truncated square pyramid is formed by single point incremental process. The formed part was analyzed for its formability and thickness distribution along with the twist induced during incremental forming process. To evaluate the system accuracy a numerical model of a truncated square pyramid is developed by means of FE simulation code Abaqus and validated experimentally. The assessment of finite element simulation with experimental work shows a good agreement between the computed and measured values. The angle of twist is less at lower and more at higher forming heights.
