Project #1

Monitoring and Diagnosis of Surface Defects of Hot Rolling Processes

Source: SME Education Foundation
PI/PD: S. Zhou
Duration: 06/2003 - 07/2004
Abstract:
Hot rolling is among the key manufacturing processes that convert cast or semi-finished steel into finished products. The surface integrity is an extremely important quality characteristic of the hot rolled products. The proposed project focuses on the monitoring and diagnosis of surface defects in hot rolling process. The basic approach is to apply advanced image processing and statistical analysis to the hot surface images collected in real-time by using an innovative imaging system. Unlike other quality assurance techniques, the proposed methodology can quickly detect the process abnormal change.



Project #2

Modeling, Analysis, and Control of Variation Propagation in Manufacturing Processes

Source: NSF
PI/PD: S. Zhou
Duration: 09/2003 - 08/2006
Abstract:
This grant provides funding for the development of a methodology for modeling, analysis, and control of variation propagation in complicated manufacturing processes. A quantitative variation propagation model will be developed. Both analytical and empirical methods based on product/process design and engineering knowledge are used to link the key process variation sources and key product quality characteristics in this model. This quantitative model allows system theory and advanced statistical techniques (e.g., variance component analysis of linear mixed models) to be adopted in quality and productivity improvement.



Project #3

Sensors and Sensor Networks: Design, Fabrication and Application of Distributed Micro Sensors Embedded in Metal Tooling

Source: NSF
PI/PD: Li
Co-PI: Zhou, Jiang
Duration: 08/2003 - 07/2006
Abstract:
The objective of this award is to develop a sensing methodology that enables highly reliable and accurate monitoring and diagnosis for manufacturing processes. This proposed research is to use a system approach to study the design, fabrication, optimization, assessment, and applications of distributed micro sensors embedded in metal tooling that is fabricated by Rapid Tooling manufacturing processes. The challenging issues involve the embeding process, the control and improvement of the embeding process, and huge dataset processing for both process and sensor failure diagnosis.



Project #4

Stream-of-Variation Analysis System for Multistage Assembly Processes

Source: NIST-ATP
PI/PD: D. Ceglarek
Co-PI: S. Zhou
Duration: 10/2003 - 11/2006
Abstract:
This project is to develop a widely applicable computer simulation system for modeling, analyzing, predicting, and optimizing the performance of multistage manufacturing processes requiring accurate parts alignment to improve production and product quality. ATP aims at bridging the gap between research labs, technology and business, and awards are made strictly on the basis of peer-reviewed competitions.
