Latest Patents

Lavisse 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 measures a workpiece’s geometry during machining and uses its geometric profile, together with a machine-learning estimation model trained on data from other workpieces, to predict deformations that may occur during later machining. A simulation model then uses those predicted deformations to estimate the residual stress field. The model is based on physical simulations that describe how residual stresses vary with the manufacturing parameters of the raw workpiece.

Career Highlights

Lavisse’s listed invention focuses on applying data-driven prediction and physical modeling to a manufacturing challenge. Estimating residual stresses during machining can help characterize how a workpiece may deform as processing continues.
