Analysis and optimization of hard turning operation using cubic boron nitride tool

The First Step to Science Innovation: Down to the Basics

“…In order to overcome the huge problem of ignorance [1][2][3][4][5][6][12][13][14][15][16][19][20][21][22][23]29,[31][32][33][34][35][36][37][38][44][45][46][47][48][49][50][51][52][53][54][55][56][57][58] a profound change of mind (metanoia, Deming) [5,6] is NEEDED: therefore we present the Theory for analyzing Scientifically the data and making Scientifically the ANOVA [17]. We limit ourselves to the very simple case of two factors, as in the case of the Nigerian "statisticians"; we assume that any datum yij is defined as generated by the following model, [ADDITIVE model] (for A, B factors) ij i j ij y e = µ + α + β + where µ provides the influence of the mean µ of the random variables Y ij , α i provides the influence of the factor A, β j provides the influence of the factor B [we do not consider αβ ij that provides the influence of the interaction AB (due to the factor A and the factor B)].…”

“…We said that the problem of ignorance is so huge [1][2][3][4][5][6][12][13][14][15][16][19][20][21][22][23]29,[31][32][33][34][35][36][37][38][44][45][46][47][48][49][50][51][52][53][54] that a profound change of mind (metanoia, Deming) [5,6] is NEEDED.…”

“…We do not present a literature review of the problem, because it will need at least hundreds of pages to be settled, both for Quality, Reliability, Statistics, Confidence Intervals and for Design of Experiments that are subjects very little known by managers and professors; we list here only few docs in the references [1][2][3][4][5][6][12][13][14][15][16][19][20][21][22][23]29,[31][32][33][34][35][36][37][38][44][45][46][47][48][49][50][51][52][53][54][55][56], taken from the hundreds of papers read by F. Galetto in his 45 years of experience/activity in the Quality Field (big and medium Corporations and Universities). We prefer to present the ideas about Science and the Scientific Attitude and Behavior (SAB).…”

Technics Research on Polycrystalline Cubic Boron Nitride Cutting Tools Dry Turning Ti-6AL-4V Alloy Based on Orthogonal Experimental Design

“…The tool wear, surface roughness, cutting forces, and metal volume removed were the responses. The cutting speed and feed rate were the most significant factors for surface roughness; specifically, the higher cutting speed produced a better surface finish [7] . In DA Fadare study, the steepest descent method was used to study the effects of cutting parameters on surface roughness of machined Ti-6Al-4V alloy workpiece at high-speed conditions.…”

Optimization of Cutting Parameters to Minimize Surface Roughness in the Hard Turning Process using Particle Swarm Optimization Algorithm

“…Conventionally, hardened steels were machined with the grinding process but it is time consuming and having limitations with the reference to geometry of the surfaces produced. Therefore, hard turning is a substitute of grinding process which gives many benefits [1,2]. Effective material removal depends upon selection of machine parameters, nature of the work-piece material and tool materials.…”
