Abstract: An outline for numerical simulation on cutting process by Finite Element Method (FEM) and required data are discussed. The recent reports concerned on the simulation and their targets are referred. An importance of material characteristics, friction one and fracture or separation criterion on practical machining phenomena is also discussed. The simulation methods on both continuous chip formation and discontinuous one are shown. The points at issue on these simulation results and the future trend of them are also discussed. Finally, an availability of the simulation and the expected fruits are discussed.

Keywords: FEM; finite element method; machining process; flow characteristics; friction characteristics; fracture criterion; continuous chip; discontinuous chip; cutting simulation.
