Latest Patents

Germain is credited with 1 patent: “Method for Estimating a Residual Stress Field in a Workpiece During Machining and Machining Process Using Said Method.”

The method estimates residual stress in a workpiece by measuring its geometry during machining and using that geometric profile to predict subsequent deformation. A machine-learning estimation model is trained on data from other workpieces, while a generic physical simulation model relates manufacturing parameters of the raw workpiece to variations in residual stress. Together, these models provide an estimate of the stress field during the machining process.

Career Highlights

Germain’s listed invention combines machine learning with physical simulation to estimate how a workpiece may deform as machining continues. The approach uses measurements taken during production, with the aim of informing understanding of residual stresses in the material.
