Department of Aeronautical and Mechanical Design Engineering, Korea National University of Transportation, Chungju 380-702,Korea(Received November 24, 2014)(Revised December 2, 2014)(Accepted December 12, 2014)Abstract Machining performance is often limited by chatter vibration at the tool-workpiece interface. Chatter vibration isa type of machining self-excited vibration which originated from the variation in cutting forces and the flexibility of themachine tool structure. Cutting tooling method is one of major factor to chatter vibration in turning process. Even thoughlots of cutting tooling methods are developed and used in machining process, precise analysis of cutting tooling effect inview of chatter vibration behavior. This study presents numerical and experimental approaches to verify and effects ofvarious cutting tooling geometry and clamping method on the onset of chatter vibration. Acquired knowledge from thisstudy will apply the optimal geometry design of cutting tooling and adjusting of machining process.Key wordsChatter vibration, Turning, Tooling, CAE (Computer Aided Engineering), Finite element analysis
