Optimizing the cutting parameters using taguchi method to reduce the cutting tool vibration

Abstract

In any machining operation, minimizing the vibration of the tool is a very important requirement for any turned workpiece. Thus the choice of optimized cutting parameter is very important for minimizing the vibration of the cutting tool. The focus of this study is the collection of tool vibration data generated by the lathe dry turning of SS304 samples of diameter 31mm using ISO 6R 1212 as the cutting tool at different levels of speed (140, 220, 360rpm), feed (0.1, 0.16, 0.25mm/rev) and depth of cut (0.5, 0.6, 0.7mm) and then analyzing the obtained data using taguchi analysis to show how tool vibration varies within a given range of speed, feed & depth of cut. The vibration here is represented by its peak acceleration. The analysis revealed that for the specified range of speed, feed and depth of cut, any change in the depth of cut causes a large change in the tool vibration while change in the cutting speed causes comparatively lowest change in tool vibration.
