Abstract

Abstract: Laser bending process has many advantages including high flexibility, production of intricate shapes, precise incremental adjustments etc. The use of Nd:YAG laser for bending thin sheet aluminium is done frequently for various operations.In this experiment laser process parameters were optimized using Taguchi method. The response parameter governing the laser beam in Aluminium sheet bending were evaluated by measuring of the bending angle. Four input parameters such as laser power, scan speed, pulse diameter and pulse duration were taken into consideration for optimization. Furthermore, 25 combinations of these laser parameters were set and Taguchi methodology is used. The optimum parameter settings are: laser power 2.8 J, pulse diameter 2.0 mm, pulse duration 0.5 ns and scan speed 60%. The optimal result was confirmed with a superior bending angle as 20 0 .
