提出了一种基于微观结构有限元切削过程仿真的切削力模型标定方法，并将其应用于球墨铸铁、灰铸铁和碳钢等黑色金属材料的切削过程。该方法结合了石墨，铁素体和珠光体晶粒产生球墨铸铁，灰铁和碳钢的微观结构，并通过正交加工模拟获得切削力。模拟的力用于执行切削力模型校准。车削过程中的切削力预测的校准的基础上，从而获得和实验表明是在良好的协议与实际切削力数据。
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.
