Bu çalışmada 80x80x30 mm ebatlarında alüminyum 6061-T651 alaşımına yüzey frezeleme işlemleri gerçekleştirilerek kesme parametrelerinin kesici takım aşınması üzerine etkileri araştırılmıştır. Yüzey frezeleme işlemi için; üç farklı kaplamaya sahip kesici uç (CVD tekniği ile TiN-TiCN-Al2O3 kaplanmış, PVD tekniği ile TiALN-NANO kaplanmış ve PVD tekniği ile ALTiN kaplanmış) üç farklı kesme hızı (250, 350 ve 450 m/dak) ve üç farklı ilerleme oranı (0.15, 0.30 ve 0.45 mm/diş) kullanılmıştır. Deneyler kuru şartlarda yürütülüp kesme derinliği 0.5 mm olarak tüm deneylerde sabit tutulmuştur. Deneysel tasarım ve optimizasyon için Taguchi metodu kullanılmış, Taguchi L9 (3 3 ) ortogonal dizisi seçilerek 9 deney yürütülmüştür. Her bir deney sonrası takım yan yüzey aşınmaları ölçülmüştür. Deneyler sonunda elde edilen değerler optimize edilmiş, varyans analizi (ANOVA), üç boyutlu grafikler ve regresyon metodu kullanılarak değerlendirilmiştir. Deneyler sonrası en düşük takım aşınması için kesme parametreleri, Taguchi metoduyla başarılı bir şekilde optimize edilmiştir. Taguchi analizi sonucu minimum aşınma değeri için elde edilen optimum kesme şartları; TiN-TiCN-Al2O3 kaplamalı kesici uç, 450 m/dak kesme hızı ve 0.30 mm/diş ilerleme oranı olarak bulunmuştur.

The Aluminium 6061 alloy is a material that is used in rims, panels and several other parts of vehicles in the automotive industry, and it has excellent machinability properties. In this study, surface milling was applied to the aluminium 6061-T651 alloy that was cryogenically treated by using TiALN-Nanocoated normal and cryogenically treated cutting inserts. The Taguchi L18 orthogonal array was selected as the experimental design. As the cutting parameters in the experiments, two different cutting inserts (normal TiALN-Nano-coated inserts and cryogenically treated TiALN-Nano-coated inserts), three different cutting speeds (250, 350 and 450 m min −1 ) and three different feed rates (0.15, 0.30 and 0.45 mm tooth −1 ) were utilised. Roughness measurements were made after each experiment, and cutting insert wear was measured by repeating the same experiment 5 times. The Taguchi method and Grey Relational Analysis for multi optimisation were used in the optimisation of the wear and roughness values. According to the results of the experiment, the cryogenic treatment showed a positive effect for the minimum cutting insert wear, while it did not have any significant effect on surface roughness. The most significant factor affecting surface roughness was the feed rate, whereas the most significant factor affecting wear was the cutting speed. On the other hand, according to the result of the multi optimisation made using the GRA method, the most significant factor affecting both wear and surface roughness was determined as the feed rate. Based on the results obtained in this study, if the minimum surface roughness and wear are desired, the findings obtained with GRA can be easily used in the manufacturing industry. Consequently, it was observed that the proposed, Greybased Taguchi methodology was effective in solving the decision-making problem involving multiple criteria as wear and roughness.

The aluminum 6061 alloy is commonly employed in the automotive industry in the manufacture of rims, panels and even the chasses of vehicles and has excellent machinability. In this study, the surface of the cryogenically processed aluminum 6061-T651 alloy was milled using both untreated and cryogenically treated TiN-TiCN-Al2O3-coated cutting inserts. The Taguchi L18 orthogonal array was chosen as the experimental design. As the cutting parameters in the experiments, two different cutting inserts (untreated and cryogenically treated, TiN-TiCN-Al2O3-coated), three different cutting speeds (250, 350 and 450 m/min) and three different feed rates (0.15, 0.30 and 0.45 mm/rev) were used. After each experiment, the surface roughness and wear values of the cutting inserts were measured, the latter after repeating the experiment five times. Wear and roughness values were optimized using the Taguchi method. Additionally, Gray Relational Analysis (GRA) was used for the combined optimization of wear and roughness values. The optimized findings determined using Taguchi optimization for minimum surface roughness were the cryogenically treated cutting insert, 250 m/min cutting speed and 0.45 mm/rev feed rate. The optimized findings for wear were the cryogenically treated cutting insert, 350 m/min cutting speed and 0.30 mm/rev feed rate. In the optimization with GRA, the common optimum parameters for surface roughness and wear were the cryogenically treated cutting insert, 250 m/min cutting speed and 0.15 mm/rev feed rate. According to the Taguchi and GRA results, the cryogenically treated cutting inserts performed the best in terms of minimum wear and surface roughness. The Gray-based Taguchi methodology proposed in this study was found to be effective in solving the decision-making problem in multi-specific results as wear and surface roughness.
