Optimization Of Dry Turning Parameters For Free Cutting Brass (Cuzn39pb3) Material Using Taguchi Method

Abstract

Nowadays, Material Development Is Focused On Continuous Improvement Of A Material?�?S Properties. In Order To Lower Machining Costs, Fabricators Frequently Demand Materials With Improved Machinability Properties While With Mechanical And Physical Properties That Are Essentially Unchanged. Pure Copper Produces Long Tubular Or Tangled Chips Which Can Make It Difficult To Machine. The Challenges Are Due To Its High Ductility And High Frictional Forces Between Chip And Cutting Tool. This Creates High Tool Wear And Poor Chip Formation. Dry Turning Operation Is Very Important Due To Save Cost Of Cutting Fluid, Contribute To Clean Environment And Safety For Operator. In This Work, Cutting Parameters (Cutting Speed, Depth Of Cut And Feed) Were Optimized For Dry Turning Process Using Taguchi Method. Surface Roughness Produced On The Machined Part Of Free Cutting Brass By Turning Process On The Conventional Lathe Machine. The Minimum Surface Roughness At Optimum Turning Parameters In This Study Was Obtained. Result Of Variance Indicates That The Contribution Of Cutting Speed, Feed And Depth Of Cut Were 88.74%, 1.13% And 6.46% Respectively. Among Which Cutting Speed Was The Most Significant Factor For Improving Surface Roughness.
