Abstract

LaserOrigami (LO) of three-dimensional (3D) AISI 304 stainless steel components, namely, the Origami spoons, is hereby investigated. The shaping process of the Origami spoons is performed by a High Power Diode Laser (HPDL). Setting of the laser operational parameters, namely, laser power, number of passes and scanning speed were experimentally investigated. In addition, the most effective sequence of laser scanning patterns is sought, being this choice strictly related to the extent and uniformiy of the plastic deformation and, above all, to the visual apperance of the bent workpiece. Numerical modelling of the forming process was performed by the Finite Element Method (FEM), developing a coupled temperature−displacement model. The experimental findings showed the wings of the Origami spoons can be shaped by HPDL with a great deal of accuracy. In addition, the numerical model can simulate the forming process with good precision and generalization capability, thus providing a reliable estimate of temperature distributions and nodal displacements.
