Model-Based Feedforward Control of Part Height in Directed Energy Deposition

Model-Based Feedforward Control of Part Height in Directed Energy Deposition

Control of the geometric accuracy of a metal deposit is critical in the repair and fabrication of complex components through Directed Energy Deposition (DED). This paper developed and experimentally evaluated a model-based feedforward control of laser power with the objective of achieving the target...
