Abstract
Hard material machining is the essential feature for the parts that are involved in the matting areas. While hard turning, so many parameters influence the accuracy of the work piece and the tool life. Cutting tool vibration is one of the remarkable parameter that margins the level of work accuracy and tool life period. The vibration analysis for the turning tool is necessary to predict the proper cutting parameters for the specific operation. The cutting tool model is created by using the Pro- E software and then it is imported in to the finite element analysis. The modal and harmonic analysis are performed in finite element analysis, also that the boundary amplitude of the cutting tool is obtained since the vibration at natural frequency level. It is concluded that the range of the frequency level depends upon the feed rate, depth of cut and cutting force. Selecting proper cutting parameters and provision of the isolation to the cutting tool may reduce the amount of vibration induced in the cutting tool. Vibration analysis helps to select the optimal cutting parameters for the hard turning operation of work materials with 45 HRC-65HRC.
