Abstract
This paper presents an investigation of the changing dynamic behavior of the machine-tool-workpiece system with variation of cutting speed, depth of cut, feed rate and feed direction in turning. The characteristics of stable cutting, chatter development and fully developed chatter regions are described. The workpiece vibration at different locations along the workpiece during chatter was continuously measured and analyzed. In addition to complex linear behavior arising as process parameters were changed, fundamental nonlinearity in the system is indicated by a path dependence of the location of the onset of chatter. The location along the workpiece at which vibration behavior changed was dependent on feed direction. It is concluded that changing the process parameter values and process configuration can have large, unexpected, nonlinear effects on dynamic system behavior.
