Formability Analysis in Incremental Sheet Forming Of Aluminium Alloy
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2017, Vol 5, Issue 5
Abstract
Non-corrosiveness and lightweight are the characteristics of aluminium due to which it is finding wider application in industries. However, forming aluminium sheet is difficult as compared to steel. Thus, emerging methods like incremental sheet forming in which formability is higher as compared to conventional method must be used for the purpose. In the current experimental work, effect of four forming parameters namely step size, wall angle, feed rate and rotational spindle speed is analysed n formability of aluminium alloy AA1100. The L9 orthogonal array is used to design the experiments. It was found that, formability is mainly affected by the wall angle. Lower feed rates are advisable for higher formability. The different modes of cracking revealed that the formability in the process is limited by necking as well as through thickness shear in the component which is due to serrated strain path resulting from cyclic plastic deformation.
