The finite element simulation of oblique cutting is a complex and professional process. It is necessary to build a system to construct a model in order to obtain simulation values more conveniently and rapidly. The key techniques of 3-D parametric modelling with MSC.Marc software metal oblique cutting simulation was presented in this investigate. The modelling rule based on the process was carried out. The system, designed using C++ Builder, can access data, which includes the geometrical angles and dimensions of tool, the sizes of workpiece, the relative position between tool and workpiece. Meanwhile their properties and cutting conditions, etc. were stored. The procedure file modelling in the MSC.Marc environment automatically is generated by the program. So the parametric modelling of simulation is completed by calling the procedure file. Further, an example was given and the simulation model was also verified. Therefore, the parametric modelling is a kind of effective way for metal cutting simulation.
