3D Parametric Modeling of Numerical Simulation on Oblique Cutting
The finite element simulation of metal machining is a complex process. It is essential to develop a system to construct a model of simulation so as to obtain simulation data conveniently and rapidly. The paper detailed the parametric modeling. The key techniques of 3D modeling with MSC.Marc software and the parametric modeling procedure of metal oblique cutting process were presented in the paper. The modeling rule based on the procedure file was investigated. The interface of the system, designed using C++ Builder, could access data, which includes the geometrical angles and dimensions of a tool, the sizes of a workpiece, the relative position between the tool and the workpiece, their properties and cutting conditions, etc.. The procedure file, which is able to model in the MSC.Marc environment, was created by the program automatically. Calling the file, the system can finish the parametrical modeling of the finite element simulation. Then an example was given and the simulation model was also run. It was proved that the parametric modeling is an effective way for metal cutting simulation.
