“…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 observation was also reported in the study of Eker et al [62] in which he was able to obtain a reduction of approximately 3.6% in dry condition when compared to MQL condition. The optimum condition for minimal cutting force is a cutting speed of 100 m/min, a feed rate of 0.15, and a depth of cut of 0.5 mm under the dry cutting condition.…”

“…The optimised set of parameters lies outside Taguchi's L18 experimentation. The results obtained are similar to those provided by Eker et al [38,62]. An ANOVA for GRG at a 95% confidence interval was utilised to determine the significance and the percentage contribution of the investigated factors on the observed performance characteristics of the Mg-3.0Zn-0.7Zr-1.0Cu alloy-based hybrid Al 2 O 3 composite.…”

“…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.…”

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.

“…over dry machining reduces the cutting temperature and cutting forces, improvement in surface finish and hardness were observed. Eker et al (2014) compared the MQL turning performance with dry conditions by applying the orthogonal CNC cutting. They reveal that the turning with MQL supply is more effective because MQL provides the benefits mainly by reducing the cutting temperature, which also increases tool life.…”

Magnesium alloys is a lightweight material establishing scope in various fields such as aerospace and automobile. Moreover, magnesium alloys are also considered as a hydrogen storage materials. In order to understand the machining behaviour of magnesium alloy a detail research is planned. In this research the turning experiments are conducted on AZ91 magnesium alloy using the L9 orthogonal array (OA) experimental design. Technique for Order of Preference by Similarity to Ideal Solution (TOPSIS) coupled with Taguchi and Analysis of Variance (ANOVA) methods are used to analysis the experiments. The influence of cryogenic soaking duration, feed, speed and depth of cut on cutting temperature, surface roughness and cutting force were studied. Based on the TOPSIS analysis the optimal combination for the better response is cryogenic soaking time of 30 min, speed of 500 rpm, feed of 40 mm/min and depth of cut of 0.3mm. As per F value the depth of cut shows the 0.4822 and next best factors are cutting speed and feed rate. The chip analysis reveals that the cryogenic soaking duration level of 60 min is found to reduce the self-ignited chips.

Bu çalışmada, hafif yapı metallerinde minimum miktarda yağlama (MMY) sistemi altındaki işlenebilirliği ile ilgili çalışmalar araştırılmıştır. Hafif metal ve alaşımlarının, işlenebilirliği son derece zor ve maliyetli malzemelerdir. Yapılan çalışmanın temel amacı, bu alanda yapılacak bilimsel çalışmalara katkı yapmak ve aynı zamanda hafif metaller ve alaşımlarının işlenmesi sırasında doğru kesici takım, işleme operasyonu ve kesme parametrelerinin seçimine yardımcı olmaktır. Çalışmanın bir diğer amacı ise MMY sisteminin otomotiv, havacılık ve uzay sanayiinde kullanımının stratejik önemi olan hafif metallerin ve alaşımlarının işlenebilirliğine etkilerini incelemektir. Bütün bu amaçlara ulaşmak için dünyada ve Türkiye'de hafif ve metaller ve alaşımlarının MMY sistemi ile işlendiği çalışmalar incelenmiş ve sonuçlarına ait bilgiler verilmiştir.
