Outcome of the Coating Thickness on the Tool Act and Process Parameters When Dry Turning Ti–6Al–4V Alloy: GRA Taguchi & ANOVA
In the primary days of Titanium Nitride tools, before
coatings, tool manufacturers appreciated the tools would last
elongate and scuffle cratering if they put a little bit of Titanium
Nitride (TiN) in the combination when making the tool. This had
the anticipated consequence, but the more TiN that was added, the
feebler and more brittle the tool became. Then someone hit on the
idea of applying a thin layer of TiN to the surface of the tool. This
study results the Turning experiment conducted on the Ti–6Al–4V
alloy of orthogonal array with Taughi grey relational analysis.

Analysis of Product Quality Through Mechanical Properties and Determining Optimal Process Parameters of Untreated and Heat-Treated AISI 1050 Alloy during Turning Operation
AISI 1050 alloy has a wide range of applications and were subjected to machining operations. The purpose of the study is to find the optimum input plain turning process parameters at three levels, using L18 orthogonal array and grey relation analysis; and to investigate the mechanical and microscopic properties of the AISI 1050 alloy before (untreated, UT) and after annealing (AN) (heat-treatment, HT) process. The results of conducted experiments revealed the optimum process parameters as following for the untreated specimens: spindle speed at 3500 r.p.m., feed 0.08 mm/rev, depth of cut at 0.6 mm, insert corner radius at 4mm, and cutting fluid concentration at 12 %, are the most optimum conditions to obtain minimum power consumption for the untreated specimens. Whereas, a spindle speed at 3500 r.p.m., feed at 0.08 mm/rev, depth of cut at 0.6mm, insert corner radius at 4 mm, and cutting fluid concentration at 12 % are the optimum parameter

Performance Evaluation of Yield Function and Comparison of Yielding Characteristics of SS 304 in Annealed and Unannealed Conditions
Sheet metal forming forms in numerous industries like vehicle depend on the yielding of the sheet metals when strained. Yielding is portrayed by plastic flow of the materials when strained. The yield point if there should be an occurrence of uniaxial tension can be effectively decided from the pressure strain diagram, yet if there should arise an occurrence of multi axial Stresses it gets complicated. A connection between the principal stresses is required determining the conditions under which plastic flow occurs. This intricacy is tended to by the anisotropic yield capacities. Likewise, the tests used to acquire yield loci might be costly and time taking in such case these yield capacities end up being exceptionally viable. The yield criteria additionally help in deciding planar distribution of yield stresses and anisotropic coefficients, which gives a decent gauge of these mechanical parameters without having to through the pain of trial assurance. This project aims at using Hill 1948 criterion to obtain the Yield surface Diagrams for SS304 in annealed and original state and subsequently obtain the planar distribution of the uniaxial yield stress and anisotropic coefficient. Also, the performance evaluation of both the distributions will be done using accuracy index
