Abstract

A knowledge of the transfer characteristics of the cutting process is one of the crucial factors needed for the assessment of the dynamic stability of the machining system. Yet, it is still not possible to obtain a reliable analytical model, neither based on theoretical considerations nor on experimental data. The objective of this paper is to introduce a method for the determination of the cutting process transfer function in the form of analytical models based on experimental data. The Dynamic Data System (DDS) approach has made it possible to adequately characterize the dynamic cutting process from observations of random force and vibration components. The theoretical concepts and modelling procedure have been demonstrated using actual experimental data. Subsequently, a comparative assessment of the obtained results is given with respect to two typical existing methods, the shear plane method and the double modulation method, representing the static and dynamic methods respectively.
