Dynamic motion of the work by vibration cutting, whose process is suitable for precision machining, is theoretically analyzed on a linear tool-work forced vibration system. The purpose of this study is to analyze the nonlinear vibration phenomena on vibration cutting. Previously nonlinear vibration phenomena during 2-dimensional vibration cutting at 20-500 mm/min low cutting speed are shown on a Poincare map. It is found that the profile of a machined surface can be analyzed by using the Poincae map. In this report, the experiments are carried out using 3-dimensional vibration cutting at 25-50 m/min practical cutting speed. It is confirmed that the nonlinear phenomena due to vibration cutting are remarkably influenced by changing the tool amplitude and the natural frequency of a work vibration system, and that in such a case, randomlike oscillations excited by vibration cutting force exhibit chaos.
