Comparative Study On The Advantages Of Using Double Cutting Tool In The Conventional Turning Process Of Cast Iron Material

Abstract

Today's Quickly Evolving New Materials Make It Difficult For Machining To Attain The Required Surface Finish. This Thesis Work Looked At The Science Of Using Two Single-Point Cutting Tools At The Same Time To Cut The Material Of The Work Piece. A Machined Component's Surface Quality Was Examined With The Effects Of Cutting Speed, Feed, And Depth Of Cut. The Impact Of Those Cutting Parameters Resulted In Increasing Temperature, Tool Wear, And Material Removal Rate. AsA Result Of Which Surface Roughness Was Investigated For Different Cutting Parameters Such As Cutting Speed (50, 70, 90) M/Min, Feed Of (0.3, 0.525, 0.75) Mm/Rev, And Depth Of Cut (0.3,0.675, 1) Mm For Single Tool Turning While For Double Tool Turning Depth Of Cut (D1 = 0.5, 0.75,1, D2 = 0.75, 1, 1.25) Mm To Improve Productivity. The Morphology Of The Chips Was Also Investigated. The Cutting Parameters Were Optimized By Turning Process Using The Response Surface Methodology Method. The Surface Roughness Was Selected As A Response Variable And The Work Piece Was Estimated By Using A Surface Roughness Profilometer. Besides, The Cutting Temperature In The Tooltip Was Predicted Using A Digital Thermometer And Examined. The Box Behnken Design Approach Was Incorporated To Formulate The Experiments And Rigorous Experimental Analysis Was Performed. Analysis Of Variance (Anova) Determined The Influences Of Cutting Parameters On The Surface Roughness. The Results Of Variance Presented That The Influence Of Cutting Speed, Feed, And Depth Of Cut Were 51.33%, 22.58%, And 6.93% For Double Tool Turning Whereas For Single Tool Turning 67.78%, 21.65%, And 1.6% Respectively. The High Surface Finish Attained At Optimum Cutting Parameters (86.76 M/Min, 0.3 Mm/Rev, And1.75 Mm) Was 1.04 ??M For Double Tool Turning While For Single Tool Turning Was 1.11??M. (90M/Min, 0.3 Mm/Rev And 0.409 Mm). For The Selected Cutting Parameters In Experimental Results Were Observed That The Material Removal Rate Was Increased By 55% During Double Tool Turning Than Single Tool Turning. Similarly, The Tool Wear Measured Shows That Total Of 0.690 Mm For Single Tool Turning While It Was Reduced To 0.419 Mm For Double Tool Turning.
