Orthotropic Experiment Research on Bending Angel of Laser Shock Forming


Article Preview

LSF is a novel forming technology brought recently. The deformation angle is the main concern of the LSF that was influenced with many factors. In order to optimize process parameters of bending with LSF, an orthotropic experimental method was introduced in this paper. The orthogonal experimental design is adopted to analyze the interaction of different processing parameters with the sample. It can give a relatively accurate description of the effect of laser processing parameters on the bending angle induced in the sample with a representative coverage of all parameters by efficient calculation. And it can make a comprehensive evaluation on coupling of process parameters. In the paper, laser bending of the AL sheet with the thickness of 0.25mm was studied by changing the laser energy, scan speed, and scanning times. The results show that the three parameters have different effects on bending angle, scanning times ranks first, followed by power and scan speed in terms of their effects on the bending angle. Scanning times have strong potential to increase bending angle of laser shock forming. The analysis results show that laser shock conditions should be carefully selected to ensure laser shock pressure for optimized deformation angle.
