Development of Three-Dimensional Parametric Modeling for Milling Process Simulation

Abstract

Metal machining simulation using finite element method (FEM) is extraordinarily complex. It is essential to develop a system so as to construct simulation model and obtain valuable results conveniently and rapidly. This study developed a parametric modeling based on MSC.Marc software, which included the key techniques of three-dimensional (3D) modeling and the parametric modeling course of metal milling process. In addition, an explanation facility based on the procedure file, which could be run automatically, was performed according to a modeling procedure. The interface of the system designed using Builder, could access data, which included the geometric angles and the dimensions of a tool and a workpiece, the relative position between them, their properties and cutting conditions, etc.. Calling the procedure file, the system approached the parametric modeling. An example was given, which simulation results indicated that it is an effective methodology to develop 3D parametric modeling.
