Optimization of DVG850 Dual-Screw Worktable System Based on ANSYS Workbench

In traditional single-screw worktable system, the system is always subjected with torque because the driving force and force-bearing point of the workpiece always change with the processing path, so its performance may be affected. Therefore, the scheme of dual-screw worktable system is put forward and modal analysis with ANSYS Workbench is made by taking DVG850 high-speed vertical machining center worktable system for example. Then four alternatives of the machine are proposed based on the position of screw and guide.Through modal analysis of different parameters of the system, we ultimately select the dual-screw worktable system with highest performance (Screws place inside of the guide and horizontal distance of the two screws is 310mm.) as the optimalizing plan. This provides a reliable reference for further study on dynamic analysis of worktable system.
