The chatter is an undesirable phenomenon that occurs in the machining of complex surfaces, especially at high cutting speeds, and which negatively affects the machining process in terms of cutting performance, tool life, final surface finish and the integrity of the machine itself. The chatter, which is defined as a regenerative vibratory state, is a complex phenomenon and difficult to control due to the numerous variables present in it. This study presents the influence of three important variables in the process, which are the natural frequency of the machining system, its stiffness constant and its damping constant. The variation of each of these factors particularly affects the machining process. For its study, the well-known stability graphs based on the Altintas and Budak model have been used. In addition, a new study method has been introduced that generates three-dimensional graphs in order to visualize in a different way the influence that the variable under study has on the variables of the process, cutting speed and penetration. |
