Multi Objective Optimization of Cutting Parameters in Turning Operation to Reduce Tool Vibration and Cutting Forces

摘要

In this project work we determine the optimal setting of cutting parameters cutting speed (N) , depth of cut(d) , feed(f) and principal cutting edge angle (Ö) of the tool to get a minimum cutting force and tool vibration. In this project dry turning SS304 of diameter 30mm as a work piece and carbide insert tool (SCMT 09T308-TN5120) is done in an automatic lathe. The range of cutting parameters are cutting speed(13.18, 20.724,33.912m/min) ,feed rate(0.105,0.16,0.25 mm/rev), depth of cut(0.5,0.6,0.7mm) and the angle (78,66,62 degree). This study highlights the use of Grey logic and use of Taguchi design to optimize the multi response in turning operation. For this purpose Taguchi design of experiment was carried out to collect the data for tool vibration and cutting forces. The result shows the optimum values of the input parameters and a confirmatory test is held to confirm the results.
