Abstract: From the view of implementation and machine protection, this paper presents a novel scheme of programming spindle-speed variation for regenerative chatter suppression. It is based on the research of the necessary conditions of chatter, from a new perspective. Through standard test method, research are carried on the influence of the interval time and the speed variation amplitude on vibration suppression effectiveness. In this work, cutting process keeps relatively more stable without motor continuous overload, which is verified by theoretical analysis and experiments.

Abstract: This paper presents a simulink block diagram which is constructed on the basis of a classical nonlinear mechanical model of machine tool chatter vibration. With varying amplitude ratio and frequency ,sinusoidal spindle speed variation (S3V) cutting process is investigated in time domain, which tests and verifies the feasibility of chatter suppression by S3V method.
