Title: Modeling the Peak Cutting Temperature During High-Speed Machining of AISI 1045 Steel
Published: May 22, 2012
Abstract: This paper presents new experimental data on AISI 1045 steel from the NIST pulse-heated Kolsky Bar Laboratory. The material is shown to exhibit a stiffer response to compressive loading when it has been rapidly preheated, than it does when it has been heated using a slower preheating method to a testing temperature that is below the eutectoid temperature. Suggestions are made as to how to modify the well-known Johnson-Cook constitutive model of Jaspers and Dautzenberg for this material to achieve improved predictions of the peak cutting temperature.
