Hardware-in-the-loop control of additive manufacturing processes using temperature feedback

摘要: Laser-based additive manufacturing is a technology for the production of freeform metallic parts. In order to produce parts with high quality, it important processes be controllable degree precision. Current systems attempt reach this goal by carefully tuning operational parameters, often in combination feedback control system. These are based on low order, empirical models process, which may limit performance that can achieved. This paper introduces system physical heat conduction model melt pool dynamics. The serves as framework applied many laser material precision required such cladding and selective melting. controller able regulate size modulating power using number surface temperature measurements signal.
