Wire Electrical Discharge Machine (EDM) for Quantifying Residual Stress and Heat Treatment Effectiveness in Additive Manufactured Metals
Abstract
Wire Electrical Discharge Machine (EDM) for Quantifying Residual Stress and Heat Treatment Effectiveness in Additive Manufactured.This proposal aims to add a wire electrical discharge machine (EDM) to the University of Louisville, for the specific purpose of enabling residual stress characterization experiments on additive manufactured (AM) metal structures. These mechanics-based measurements will facilitate current preliminary research studies examining the effectiveness of post-fabrication processing, and will augment previous Department of Defense studies performed at the University of Louisville related to the strength and fatigue performance of AM components. The particular experiments envisioned are based on the slitting method/crack compliance method of determining residual stress. The nearly stress-free cutting method provided by Wire EDM for sectioning metal components is a major requirement of these residual stress measurement techniques.
