【Abstract】 On the basis of kinematics and geometry principle,a 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 curves have been figured by using Visual Basic language.Before the double rocker arm mechanism was applied in the machining process,the lengthes of variable arms and their correlative angles were optimized.The best parameter combinations which can fulfill the application requirements were found.The optimal mechanism has been applied in the lapping process of cubic boron nitride.更多还原
