Experimental Studies on Vibration Characteristics of Lathe Machine Tool under Different Cutting Conditions

In this paper the chatter vibrations in metal cuttings on lathe machine is investigated experimentally. Since the dynamic cutting force is strongly influenced by the variations of cutting parameters, the objective of present paper is to consider the variations of cutting speed, feed and depth of cut on the vibrations of cutting process on the lathe machine, By analyzing experimental results it can be concluded that maintaining appropriate cutting parameter play important role in suppressing vibration that are developed during metal cutting process. For each of cutting conditions, the variations of cutting force component (thrust force) as a function of time are obtained numerically and treated as the input excitation for the lathe machine. The measurement of vibration in terms of acceleration by accelerometer is expressed as a function of time.
