Abstract: This paper presents a systematic stability analysis of spindle speed variation (SSV) method for machining chatter suppression based on a machining chatter model of non-linear delay differential equation. The theoretical results are verified by results of numerical simulations and experiments. Some important results are achieved: the stability increment index (SII) of SSV cutting over constant speed cutting is derived; a formula for selecting the SSV amplitude is proposed based on the internal energy analysis of the SSV cutting and the instantaneous sideband effect, which is meaningful for practical application of SSV cutting.
