Layer-to-layer control of laser metal deposition processes

Lie Tang

Abstract

"Laser Metal Deposition (LMD) is a promising technology for Solid Freeform Fabrication. It allows fabrication of functional metal parts directly from CAD solid models, which reduces the machining and material costs. Typically, constant process parameters are selected, resulting in a non-uniform track morphology, increased machining cost, powder waste, etc. To address these problems, this dissertation develops automatic control methodologies to implement closed-loop LMD process control"--Abstract, page iv.
