...Mohamed Slamani; Rene Mayer; Marek Balazinski; Serafettin Engin During high-speed end mill boring, dynamic scale mismatch originates from the difference in the dynamic response of each axis and, at high feedrates, causes a trajectory ovalization along the axis with the fastest dynamic response...

...Emre Ozlu; Erhan Budak In this part of the paper series, chatter experiments are conducted in order to verify the proposed stability models presented in the first part ( Ozlu, E., and Budak, E., 2007, ASME J. Manuf. Sci. Eng., 129(4), pp. 726–732) . Turning and boring chatter experiments...

...Emre Ozlu; Erhan Budak In this paper an analytical model for stability limit predictions in turning and boring operations is proposed. The multidimensional model includes the three-dimensional geometry of the processes resulting in an eigenvalue problem. In addition, a model for the chip thickness...

...Hussien M. Al-Wedyan; Rama B. Bhat; Kudret Demirli An approach to study the whirling motion of the BTA (boring trepanning association) deep hole boring system is presented by introducing the system excitation in the form of internal forces between the boring bar and the workpiece. This involves...
