Simultaneous Visible and Thermal Imaging of Metals During Machining

March 28, 2005
Author(s)
Eric P. Whitenton, Robert W. Ivester, Howard W. Yoon
In order to investigate temperatures reached during orthogonal metal cutting, a novel approach for measuring temperatures at the tool-chip interface has been developed based on high-speed thermography. A thermal infrared camera and a visible camera

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
