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.

- International Journal of Machining and Machinabilty of Materials is a refereed international publication in the field of machining and machinability of materials. Machining science and technology is an important subject with application in several industries. Parts manufactured by other processes often require further operations before the product is ready for application. Machining is the broad term used to describe removal of material from a workpiece, and covers chip formation operations - turning, milling, drilling and grinding, for example. Machining processes can be applied to work metallic and non metallic materials such as polymers, wood, ceramics, composites and special materials. Today, in modern manufacturing engineering, there has been strong renewed interest in high efficiency machining.
