Process Parameter Optimization of Laser Forming Based on FEM-RSM-GA Integration Technique

Abstract:

A process design tool is proposed for parametric optimization of laser forming based on integrated Finite Element Method, Response Surface Method and grey Relation analysis. A sequentially integrated FEM-RSM-GRA framework has been developed and implemented to determine the optimum parameters for maximum bend angle, minimum heat affected zone (HAZ) and minimum residual stress. Four process parameters namely power, scanning velocity,spot diameter and sheet thickness had been consideredhave been optimized to minimize the distortion of the structure. The optimization results revealed the effectiveness of the methodology for process design of laser forming of AISI stainless steel sheet with reduced haz and residual stress.
