The cutting performance relates to the dynamic properties of the whole system of the tool, spindle and machine tool frame. The impact of the machine frame properties on the dynamic properties at the tool end point is studied both experimentally and using a coupled simulation model. Coupled model of the whole mechanical system is created as a system joining the spindle detailed model and machine frame FE model. Shift in the spindle and tool system dynamic properties, related to the machine frame properties, is proved using the coupled model. Experimental verification of the FRF evaluated at the tool is extended also by cutting tests. Good match of the simulated dynamic properties of the whole system with the real behaviour is found.
