Experimental Study And Optimization Of Cutting Parameters During Dry Turning Of Aisi 1026 Steel

Abstract

Increasing Quality And Productivity Of Machined Parts Are The Main Challenges Of Machining Operations In Metal Working Industries. Turning Is One Of The Most Widely Used Machining Operations To Remove Material And Produce Reasonably Good Surface Finish Quality, Which Is Influenced By Different Factors Like Cutting Speed, Feed Rate, Tool Geometry, Cutting Tool And Cutting Fluid. Dry Turning Is Applicable For Conventional Machining On Steels, Steel Alloys And Cast Irons And It Has Advantages In Respect To Environmental Aspects, Minimizing Cost Of Fluid To Be Used And For Safety Of Operators. Optimizing Of Cutting Parameters Plays A Vital Role In Improving Surface Finish That Minimizes Mechanical Failures Caused By Wear, Corrosion, And Increasing Productivity Of The Products. This Research Focused On Experimentally Studying And Optimizing Cutting Parameters (Spindle Speed, Depth Of Cut, And Feed Rate) On Surface Roughness, Material Removal Rate, Tool Tip Temperature, Machining Time And Tool Wear Rate In Dry Turning Of Aisi 1026 Steel Using Carbide Cutting Tools. Taguchi L9 Orthogonal Array Was Selected For The Design Of The Experiment And Analysis Of Variance Was Used To Determine The Effect Of Cutting Parameters On End Responses. The Result Revealed That Spindle Speed Has The Highest Contribution (63.78%) Followed By Feed Rate (27.78%) In Affecting Surface Roughness. Minimum Surface Roughness (1.063??M) Was Attained At 1100 Rpm Spindle Speed, 0.2 Mm Depth Of Cut And 0.05 Mm/Rev Feed Rate And Maximum Surface Roughness (2.787 ??M) Was Attained At 500 Rpm Spindle Speed, 1 Mm Depth Of Cut And 0.15 Mm/Rev Feed Rate. Material Removal Rate Was Significantly Affected By Depth Of Cut Followed By Feed Rate And Spindle Speed, And Its Value At Optimal Surface Roughness Was 4148.63 Mm3/Min. Machining Time Is Significantly Affected By Feed Rate (With A Contribution Of 64.82%), Followed By Spindle Speed (29.62%) And Depth Of Cut (2.50%).Minimum Tool Wear Rate (0.855 Mm3/Min) Was Attained At 500 Rpm Spindle Speed, 0.2 Mm Depth Of Cut And 0.05 Mm/Rev Feed Rate. An Increase In Spindle Speed Results In An Increase In Tool Tip Temperature, Which Has A Direct Influence On Tool Wear Rate.
