| ABSTRACT Increasing of the Maximum Metal Removal Rate (MMRR) in machine tools requires high width of metal removing and machining speeds. This condition cause to change cutting speed and arises vibration on cutting tool. This phenomenon leads to such problems as detrimental effects on the machined surface finish and decreasing the machining efficiency and has adverse effect on the work surface finish, high machining force, tool wear and tool life. Due to the dynamic interactions between cutting tool and workpiece, there occurs self-excited chatter vibration. In this study, chatter prediction is investigated for orthogonal cutting in turning operations. Therefore, the linear analysis of the single degree of freedom (SDOF) model is performed by applying oriented transfer function (OTF) and τ decomposition form to Nyquist criteria. Chatter frequency predictions obtained from both forms were compared with modal analysis and cutting tests. Computer programs required for both forms were written by MATLAB program. | ||||
