Advanced Manufacturing and Surface Engineering Laboratory | Institute for Sustainable Manufacturing

Overview

The Advanced Manufacturing and Surface Engineering research program (AMSE) at the University of Kentucky is primarily concerned with the development and modeling of advanced manufacturing processes, particularly machining and finishing operations. The overarching goal of the AMSE Lab is the development of industrially-viable, real-time processes models and tools that will enable the sustainable development of new products and improve US manufacturing competitiveness, as well as national security.

Through in-situ experimental observation using digital image correlation in ultra-high speed (~1 million frames/second) microscopy, the AMSE Lab is building computationally-efficient predictive, physics-based/machine-learning hybrid models. Such models can accurately capture the complex behaviors that characterize finishing operations, while enabling real-time industrial deployment. It is envisioned that through faster and more predictive process modeling, highly scalable manufacturing processes such as machining, polishing and grinding can be used to induce engineered surface and sub-surface properties, such as compressive residual stress profiles and micro/nano-textured surfaces.

Current research thrust of the AMSE Lab include:

In-situ characterization of machining and finishing processes
Computationally-efficient modeling of advanced manufacturing processes
Physics-based/Machine-learning hybrid modeling
Real-time quality (surface integrity) monitoring and control for machining and finishing
Development of advanced cutting edge microgeometries
Development of sustainable cooling/lubricating strategies
Development of novel machining strategies
