Dynamic Material Properties for Machining Simulation Using the NIST Pulse-Heated Kolsky Bar

Published

Author(s)

Richard L. Rhorer

Abstract

The modeling or simulation of machining processes is important for economically implementing new manufacturing processes such as high-speed milling or ultraprecision machining. Knowing if a process will provide the required output prior to investing in expensive equipment is vital. All machining process models, including those for ultra precision processes, are dependent on knowing the appropriate material properties. The NIST Pulse-heated Kolsky Bar is an experimental apparatus built for measuring the dynamic material properties at elevated temperatures useful in machining models. Stress-strain curves for AISI 1045 steel obtained at strain rates of over 2000 /s and high temperature (over 900 C) are presented.
