“…Sharma et al [48] found that alumina/graphene hybrid nanoparticles lowered tool wear and cutting temperature with increase in concentration of nanoparticles in turning AISI 304 steel. Viswanathan et al [54] detected in their analysis that MQL yielded low tool wear, surface roughness, cutting forces and cutting temperature in turning magnesium alloys when compared to dry machining conditions. Mahboob Ali et al [24] examined the effects of aluminium oxide nanolubricant as cutting fluid in turning of titanium alloys.…”

Nowadays industries are looking forward for a sustainable manufacturing. Nanofluid with minimum quantity lubrication is one technology in the areas of green manufacturing, which minimizes the pollution caused to the environments. The aim of this work was to examine the influence of silver nanoparticles-based cutting fluid with minimum quantity lubrication in turning on titanium (grade 2) by changing the environmental conditions. Taguchi's L 27 orthogonal array has been selected to execute the experimental trials. The responses considered are surface roughness, temperature and tool wear. The process parameters selected for this analysis were environment, cutting speed, feed and depth of cut. The principal component analysis was used to determine the optimal conditions in turning parameters. It was noticed that environment is the key parameter in defining the responses. Under optimal conditions, the surface roughness has been decreased by 89%, temperature has been reduced by 44% and wear on the tool has also been reduced. The tool wear and chip morphology were reviewed through scanning electron microscope for a complete study.

“…Though the application of MQL requires a lower cutting force than dry cutting, this was not the case in every trial. Other researchers also reported similar results [38,62]. Viswanathan et al [38] conducted turning experiments on AZ91D Mg alloy in dry and MQL condition and suggested dry cutting condition over MQL to achieve minimum cutting force.…”

“…Similar studies were conducted by other researchers who found that cutting feed had the greatest influence on the surface characteristics of Mg-based materials [33][34][35][36]. In addition, optimisations were performed to minimise the cutting force and the energy consumption required during the machining process [37,38].…”

“…Initially, this method was used to evaluate the performance of a complex project where little information/ data is available. At present, this method is widely used to optimise multi-response problems using different machining processes [37,38]. The present study considers ranks (as opposed to real values) derived from the grey relational grading system.…”

A high strength-to-mass ratio makes the use of metal matrix composites acceptable for a wide range of engineering applications. However, their use is often complicated, and machining such composites involves several challenges. During the machining process, controllable machining parameters need to be optimised to achieve multiple objectives. In this work, an attempt was made to streamline the turning parameters of a magnesium/alumina hybrid composite under dry and minimum quantity lubrication (MQL) cutting conditions. Experiments were carried out based on Taguchi's L18 orthogonal array. The input parameters (i.e. cutting conditions, cutting speed, feed and depth of the cut) were considered the cutting factors, while surface roughness, cutting force, specific power consumption, and cutting temperature were the response variables. A grey relational analysis (GRA) and the techniques for order preferences by similarity to ideal solution (TOPSIS) method were employed to improve the straight turning process of hybrid composites and to optimise the input control factors. The percentage contribution of each input parameter was identified by creating an analysis of variance (ANOVA) table. Based on the data given in the response table and the ANOVA table for the GRA and TOPSIS, feed rate was found to be the most influential parameter of those investigated in the present study, followed by the depth of cut, cutting conditions, and cutting speed. The GRA and TOPSIS produced two unique sets of optimised parameters. The optimised parameter combinations obtained using the GRA method were cutting condition = MQL, cutting speed = 100 m/min, feed rate = 0.15 mm/rev, and depth of cut = 0.50 mm; using the TOPSIS, the optimal value for cutting speed changed to 150 m/min when all other parameter values were kept the same as they were for the GRA. However, from the results of the validation tests, it was clear that the optimised parameters obtained from the TOPSIS produced a machined composite with better properties than the composite produced using the GRA.

ÖZTornalama işlemlerinde, istenmeyen yüksek değerlerdeki yüzey pürüzlülük ve titreşim değerlerini gidermek için iş parçaları tezgâha doğru bir şekilde bağlanması gerekmektedir. Bir iş parçası; uygun bir basınç ile ayna ve punta arasına bağlanmadığında, bu, onun eksenden kaçık salgılı bir şekilde dönmesine ve ölçü tamlığının bozulmasına yol açmaktadır. Bunun sonucunda, iş parçasında istenmeyen, yüksek değerlerde yüzey pürüzlülük ve titreşim değerleri meydana gelir. Bu çalışmanın amacı, Taguchi metodunu kullanarak AISI 304 paslanmaz çeliğinin tornalanmasında en düşük yüzey pürüzlülüğü ve titreşim değerlerini elde etmek için en uygun ayna ve punta basıncını tespit etmektir. İşleme deneylerinde, sabit kesme hızı, ilerleme ve kesme derinliğinde 5 farklı ayna ve punta basıncı kullanılmıştır. Deney tasarımı için Taguchi L25 (5^2) ortogonal dizilimi seçilmiştir. En küçük en iyidir yaklaşımına göre S/N (sinyal/gürültü) oranı kullanılarak yüzey pürüzlülüğü ve titreşim değerleri için en uygun ayna ve punta basıncı belirlenmiştir. S/N oranlarına göre optimum ve en düşük titreşim değerlerini veren ayna ve punta basıncı sırasıyla 18 bar ve 5 bar iken, optimum yüzey pürüzlülük değerlerini veren ayna ve punta basıncı değerleri ise sırasıyla 18 bar ve 11 bar olarak tespit edilmiştir. Fakat en düşük yüzey pürüzlülük değeri ise ayna basıncı 18 bar ve punta basıncı 5 barda elde edilmiştir. Taguchi deney tasarımındaki S/N oranı sonuçlarına göre, yüzey pürüzlülüğü ve titreşim üzerinde ayna basıncının punta basıncından daha etkili olduğu ortaya çıkmıştır. Sonuç olarak; ayna ve punta basıncı parametrelerinin optimizasyonu için Taguchi yöntemindeki faktör tasarımının; basit, sistematik ve verimli bir yöntem olduğu anlaşılmıştır.

When a workpiece is not attached with an appropriate pressure between chuck and tailstock, this will cause it to rotate eccentrically out-of-axis and deterioration of dimensional accuracy. As a result of this, undesirable high surface roughness values and vibrations in the workpiece occur. The aim of this study is to determine the optimum chuck and tailstock pressure using Taguchi method in order to obtain the lowest surface roughness and vibration values in turning of AISI 304 stainless steel. In the machining experiments, at constant cutting speed, feed and depth of cut, 5 different chuck and tailstock pressures, were used. For the experimental design, Taguchi L25 (5^2) orthogonal array was chosen. According to th...
