| Abstract Scope |
Laser sheet metal forming—along with additive manufacturing—is nearly unique in that it has been developed using an ICME-style research paradigm since its inception. Modeling both the thermal input and the mechanics of bending, then linking those processes together, is critical to realizing the full manufacturing process at an industrial scale. This work describes the development, validation, and application of an analytical, forward-stepping thermal model for laser forming in MATLAB, derived from computationally efficient models for additive manufacturing and welding. Small-scale, high-throughput laser forming experiments are used to link the thermal model outputs across laser forming parameter space with predictions of bending mechanism and extent. Finally, gaps in the current ICME approach are discussed, such as the changing absorptivity during multipass laser forming experiments. |
