Regenerative Chatter Vibrations of Turning Workpiece (3rd Report, Mesurements of Dynamic Characteristics of Cutting Process and Comparision with Ones Predicted from Static Cutting Data)

Abstract

The dynamic cutting process of the turning workpiece resisting regenerative chatter mainly depends on its inner and outer modulation. In this paper, the dynamic cutting characteristics of inner and outer modulation are estimated from dynamic cutting data obtained from experiments without special apparatus. The estimated characteristic values of dynamic cutting process are compared with the ones predicted from static cutting data by the authors' method in a previous paper. As a result of somewhat modifying that method, the predicted values correspond well to the estimated ones at a cutting speed of beyond 40 m/min.
