A workpiece manipulation assembly includes two main parts. 1. A base permanently connected to a spindle. 2. A pallet manipulated by a rotary manipulation table from working place to setting place & vice versa. This assembly is rotating around the spindle axis. The FEM analysis and analytical analysis of the workpiece exchange manipulation system of vertical turning centre, deals with stress and deformation of an assembly that is composed by the base, the palette and the other parts, at high revolution load. As requirements of customers increase – revolutions of the workpieces increase. This leads to increase the load of parts.
