Numerical And Experimental Investigation Of Deformation In Laser Forming Process

The laser forming process is an advanced process in sheet metal forming in which laser heat source is used to shape the metal sheet. In this paper, temperature distribution in sheet metals is investigated numerically and experimentally. Laser heat source is applied through curve paths in square sheet metal parts. Finite element simulation is performed with ABAQUS/CAE standard software package. Material property of AISI 1010 is used in FE model and experiments. The aim of this study is to identify the response related to deformation and characterize the effects of process parameters respect to the bending angle for a square sheet part. An experimental setup including a Nd:YAG laser, Model IQL-10, with maximum mean laser power of 500 W is used for the experiments to verify FEA results. It is observed that numerical results relatively are in agreement with the experimental results. Result show that the increasing laser power influenced the deformed shape.
