Advanced Process Monitoring in Additive Manufacturing

Manufacturing Cell Monitoring Process

This paper describes all the manufacturing cell monitoring process particularities, and its several features. It is also done a brief presentation of the data structure used to monitor the manufacturing cell status, and it is explained its achievement and its philosophy by a complete flowchart. 1.Introduction and brief description The monitoring process of the manufacturing cell deals with the ...

Laser Additive Manufacturing Process Planning and Automation

This paper presents a Laser Additive Manufacturing Process Planning (LAMPP) being developed at the University of Missouri-Rolla. The off-line planning recognizes difficult-to-build features from an STL file, selects optimal part orientation and building directions based on the skeleton information of the object geometry, and optimizes the sub-process sequences for deposition and machining. Duri...

Scalable Linking of Slice Layer Information with Process Monitoring Data in Additive Manufacturing Machines

In smart connected factories, manufacturing machines are capable of generating vast amounts of process data generated internally from within its control systems or from sensors coupled with the process. This streaming data must be stored and queried to perform data analytics or closed loop control to improve manufacturing processes. Currently, structured data schemas are ineffective in handling...

Thermographic Microstructure Monitoring in Electron Beam Additive Manufacturing

To reduce the uncertainty of build performance in metal additive manufacturing, robust process monitoring systems that can detect imperfections and improve repeatability are desired. One of the most promising methods for in situ monitoring is thermographic imaging. However, there is a challenge in using this technology due to the difference in surface emittance between the metal powder and soli...
