Abstract

The laser forming process of sheet metal has been extensively analyzed, but few attempts have been made in the area of process design. The task of the process design in the laser forming of sheet metal is to determine a set of parameters, including laser scanning paths, laser power, and scanning speed, given a prescribed shape. Response surface methodology is used as an optimization tool. The propagation of error technique is built into the design process as an additional response to be optimized via desirability function and hence make the design robust. Focusing on a class of shapes, the design scheme is applied progressively in four cases in which issues such as a large number of design variables are properly addressed.
