A methodology for mechanistic cutting force model calibration via microstructure-level finite element cutting process simulation is presented and applied to ferrous materials, including ductile and gray irons and carbon steels. The methodology combines graphite, ferrite, and pearlite grains to produce ductile iron, gray iron, and carbon steel microstructures and obtains cutting forces via orthogonal machining simulations. The simulated forces are used to perform the cutting force model calibration. The cutting forces for the turning process are predicted based on the calibration thusly obtained and experimentally shown to be in good agreement with actual cutting force data.
