Abstract

The vertical computer numerical control (CNC) milling machine is used in various industries and exhibits different proficiencies for different workers. Therefore, many companies have required the automation of the vertical milling machine to reduce human error. In this study, five cutting conditions were selected to predict the cutting force using the design of experiment, and the mechanical property of hardened mold materials was examined by a cutting experiment and FEM simulation The results show that for each cutting condition, the simulation value and experimental cutting force value are different; however, the differences have similar tendencies. In addition, the cause of deviation was analyzed to be friction and the mechanical property. In this study, we could examine the material property by simulation and experiment of the cutting force.


Keywords: Cutting force, Finite element method (FEM), Hardened mold steel, Down milling, Prediction
