Synopsis

The two degrees of freedom dynamic model was established in the feeding and radial direction. It was based on the cylindrical turning processing mechanism of vibration and chatter, the criteria of the stability of cutting system were determined, and the limit cutting width of the cutting system were given in this research, and the influences of cutting vibration also were analyzed by computer simulation. The mechanical parameters and dynamic parameters of machine tool cutting system were determined by using impulse technique modal test and orthogonal cutting tests method. The limit cutting in the nickel-based super alloy were predicted; the main components of machine tool also was used for the modal test, which provides the basic for determining the main vibrating system. By the test of cutting time-varying cutting depth, to test the predicted limiting cutting width of nickel-based superalloy and determine the validity of the main vibration system choice; using a single factor of cylindrical turning test and combining with the results of numerical simulation to study the cutting parameters analyze the influence law of process parameters on surface roughness.
