Abstract: Modeling of Finite Element Method (FEM) of metal machining is complex. Parametric modeling in the modeling system applied has a vital and practical significance for more convenient and rapid simulation for a consumer. Therefore, the whole modeling procedure of the metal cutting process with Marc is presented in this study. Some key techniques of orthogonal cutting modeling are further discussed, e.g., focusing on the rule to create a procedure file that is able to generate a FEM model automatically, as well as the system’s interface, designed using C++ Builder. The file accesses data with the help of a mechanism,which include the geometrical angles and dimensions of a tool, the sizes of a workpiece, the relative position between a tool and a workpiece, their properties and cutting conditions, etc. Furthermore, several cases studies are performed to analyze simulation models, an interface and simulation results. And the experimental results are compared with the simulated ones for the cutting force and temperature that demonstrated the effectiveness of the proposed parametric modeling for the metal machining process simulation.
