Estimation of the Frequency Response Function of the Rotational Degree of Freedom

One of the factors that influence dynamic characteristics machining systems is cutting tool. Cutting tools are very diverse, and receptance coupling substructure analysis (RCSA) essential for analyzing each For RCSA, a full matrix equipment essential. In this study, rotational degree-of-freedom was estimated analyzed using translational receptance. Displacement/moment according to distance response point first-and second-order finite difference methods. The rotation/moment point. Rotation/moment Schmitz’s method compensation strategies. limitations these strategies were analyzed, beam under free-free boundary conditions predicted second strategy.
