Join the School of Manufacturing Systems and Networks for a seminar on the In-situ Characterization and Modeling of Surface Integrity in Machining.
About the speaker
Julius Schoop is an expert in materials science and manufacturing processes, blending applied and theoretical expertise in advanced machining and finishing. He earned a bachelor’s degree in chemical physics from Centre College in 2011 and a doctoral degree in materials science and engineering from the University of Kentucky in 2015. He later served as a postdoctoral researcher at the Institute for Sustainable Manufacturing. In 2016, Schoop joined TechSolve, Inc. as program manager and principal engineer, leading projects in sustainable machining and process development for manufacturers. He returned to the University of Kentucky in 2018 as an assistant professor of sustainable manufacturing, focusing on digitally enabled manufacturing and advanced surface finishing. Promoted to associate professor with tenure in 2023, he now holds the endowed Erwin J. Nutter Professorship in the College of Engineering and a joint appointment in chemical and materials engineering. Schoop has authored 26 peer-reviewed articles and secured over $5M in federal funding from agencies like the Department of Energy, Department of Defense, Air Force Research Lab and Army Research Lab. He also founded IMPI LLC in 2020, a manufacturing consulting startup supported by the U.S. Air Force, collaborating with aerospace and defense OEMs. As a 2022 NSF CAREER awardee, his work emphasizes in-situ material characterization and digital process modeling.
Abstract
With the rise of near-net-shape manufacturing methods like precision casting, extrusion and additive manufacturing, high-performance finishing is critical. Surface and sub-surface characteristics from processes such as machining, grinding and shot peening significantly impact the functionality of components like turbine blades and biomedical implants. However, existing surface integrity models often lack predictive power or are computationally intensive, leading to reliance on empirical methods and limited use of finishing processes for proactive surface engineering. Additionally, parameters like residual stresses and micro-hardness are absent from the emerging digital thread. This seminar introduces a novel approach combining high-speed in-situ characterization and semi-analytical modeling for real-time surface integrity prediction. Using a unique testbed developed at the University of Kentucky, process-specific material properties are efficiently captured, enabling physics-based models to predict surface integrity evolution in real time. Experimental findings on sub-surface displacement fields and residual stress profiles, along with their implications for sustainable product and process design, will also be discussed.
