【Abstract】 As an important tool to research, design and analyze the complicated problems, the computer simulation technology has been employed in many fields such as mechanical engineering, automatic control engineering and national defense construction. The computer simulation technology was applied firstly in the precision machining process of superhard materials. On the basis of kinematics and geometry principle, the mathematical model for the double rocker arm mechanism was established. The movement path equation of the workpiece center point on the double rocker arm was derived. The computer simulation software was developed and the path curve was figured by using Visual Basic language. Before the double rocker arm mechanism was applied in the machining process, the length of varies arms and their correlative angles were optimized. The best parameters combinations which can fulfill the application requirement were found. The optimal mechanism was applied in the polishing process of superhard material.更多还原
