Smart Machining Systems: Issues and Research Trends

November 1, 2005
Author(s)
Laurent Deshayes, Lawrence A. Welsch, Alkan Donmez, Robert W. Ivester, David E. Gilsinn, Richard L. Rhorer, Eric P. Whitenton, Florian Potra
Smart Machining Systems (SMS) are an important part of Life Cycle Engineer-ing (LCE) since its capabilities include: producing the first and every product correct; improving the response of the production system to changes in demand (just in time)

Mechanical and Thermal Behavior for Machining TI-6AI-4V with AIMgB 14 and WC-CO Tools

August 1, 2005
Author(s)
Laurent Deshayes, J L. Evans, Robert W. Ivester, D G. Bhat, S A. Batzer
Many of the currently used tool materials will dissolve, diffuse, and/or react with titanium due to high temperatures at the tool/work-piece interface. Potential next generation tool materials that would improve the machining of titanium and eliminate the

Serrated Chip Morphology and Comparison with Finite Element Simulations

November 1, 2004
Author(s)
Laurent Deshayes, Robert W. Ivester, T Mabrouki, J F. Rigal
The complexity of chip formation in machining processes stems from the confluence of several physical phenomena - mechanical, thermal, and chemical - occurring at very high strain rate. The prediction of chip morphology depends on a fundamental

Influence of Heating Rate on Flow Stress in High-Speed Machining Processes

April 1, 2004
Author(s)
Timothy J. Burns, Robert W. Ivester, Michael Kennedy, Richard L. Rhorer, Matthew A. Davies, Howard Yoon, Lyle E. Levine, Richard J. Fields, D Basak, Eric P. Whitenton
For several decades, a major focus of machining research has been the measurement and prediction of temperature. Here, the influence of the rate of heating on the flow stress, and the implications of this for finite-element modeling of high speed metal

Material Modeling and Experimental Study of Serrated Chip Morphology

April 1, 2004
Author(s)
T Mabrouki, Laurent Deshayes, J F. Rigal, Kevin K. Jurrens, Robert W. Ivester
Machining chip morphology stems from mechanical, thermal, and chemical phenomena. Chip morphology prediction depends on a fundamental understanding of these phenomena and is industrially important for cutting force prediction and surface integrity control

Cycle-Time Reduction in Machining by Recursive Constraint Bounding

January 1, 1997
Author(s)
Robert W. Ivester, S Malkin
Modeling uncertainty in machining, caused by modeling inaccuracy, noise and pro- cess time-variability due to tool wear, hinders application of traditional optimization to minimize cost or production time. Process time-variability can be overcome by
