Book ChapterDOI
Aerospace applications of laser additive manufacturing
TL;DR: In this paper, the authors analyze the characteristics of aerospace components favoring AM, discuss different aerospace applications benefit from different AM processes, and describe the repair applications for aerospace components, and discuss the challenges of applying AM to the aerospace industry and potential future aerospace applications.
Journal ArticleDOI
The Investigation of Gravity-Driven Metal Powder Flow in Coaxial Nozzle for Laser-Aided Direct Metal Deposition Process
TL;DR: In this paper, a 3D numerical model is introduced to quantitatively predict the powder stream concentration variation in order to facilitate coaxial nozzle design optimizations, and the results are compared with the experimental data using prototyped coaxial nozzles.
Journal ArticleDOI
Integrated Process Planning for a Multiaxis Hybrid Manufacturing System
Journal ArticleDOI
Process planning strategies for solid freeform fabrication of metal parts
TL;DR: In this paper, the authors proposed a process planning for metal deposition, which consists of three major modules: spatial decomposition, slicing of the part, and toolpath generation for every slicing layer.
Journal ArticleDOI
Vision-based defect detection in laser metal deposition process
TL;DR: In this paper, the authors summarize the research on a low-cost vision system to study the laser metal deposition process and detect any thermal abnormalities which might signify the presence of a defect.
