Workpiece dynamics during stable cutting in a turning operation
In this investigation, workpiece and cutting tool dynamics in a turning operation are investigated. It is shown that dynamic information from the workpiece propagates to the cutting tool more consistently in the tangential cutting direction than in the radial cutting direction since there is a preload that seeks to keep the tool in contact with the workpiece. Finally, trajectories in the state space comprised of workpiece accelerations parallel to the radial and tangential cutting directions were investigated and it is graphically shown that stable cutting results in more organised dynamics and unstable cutting results in less organised dynamics, which agrees with previous work.
A virtual prototype model of machine tool is constructed by using the Pro/E software and the ANSYS software.Considering the effects of joints,this paper makes a study of dynamic analyses of machine tool and the effect of joints on the dynamic characteristics of machine tool to attain the purpose of synthetically predicting and evaluating the NC machine tool dynamic performance without a physical sample.
