Phase Change in Hard Machining

Phase change was truly coupled in machining models.  This work has never been successfully done by others before.  A metallo-thermo-mechanical coupled numerical framework was developed to solve for the evolution of microstructural phase constituents, cutting temperature, chip morphology, and cutting force simultaneously.
