Prediction of the Spindle and Tool Receptance : Industrial Application in Reaming Process

It is proposed to apply a methodology in order to evaluate the ability of different machining systems (Spindle/Tool) to run a reaming process in a stable way.The methodology is based on an experimental measurement of the dynamic behavior for the system including the spindle and the tool holder. Then, by coupling frequencies response functions, a new system (Spindle/Tool) FRF is predicted at the tool tip. Finally, the critical depth of cut is analytically calculated from the eigenvalues of the characteristic equation of the dynamic reaming process.
