“…Kesme hızının artması ile kesme kuvveti bileşenlerinin ve esas kesme kuvvetinin azalması kesme bölgesindeki ısının yükselmesi iş parçasının kayma dayanımının azalması ve takım/talaş ara yüzeyi temas alanının azalması ile açıklanabilir [26,30,31]. İlerleme miktarının artışına bağlı kesme kuvveti bileşenlerinin ve esas kesme kuvvetinin artması literatürde yaygın olarak karşılan bir durumdur [32][33][34].…”

Yapılan çalışma iki bölümden oluşmaktadır. Birinci Bölüm, Monel 400 alaşımının farklı kesme parametrelerinde tornalanması sonucu kesme parametrelerinin kesme kuvveti bileşenlerine ve esas kesme kuvvetine etkileri değerlendirilmiştir. İkinci bölüm ise farklı kesme parametrelerinde yapılan tornalama deneylerinde ölçülen kesme kuvveti bileşenlerinin Yapay Sinir Ağları (YSA) yöntemiyle tahmininden oluşmaktadır. Çalışmada kesme parametresi olarak üç farklı kesme hızı (60-85-110 m/dak), üç farklı ilerleme miktarı (0,05-0,07-0,09 mm/dev) ve üç farklı kesme derinliği (0,4-0,8-1,2 mm) seçilmiştir. Kesme kuvveti bileşenlerinin (Fz, Fx ve Fy) ölçümü A KISTLER 9257 B tipi piezoelektrik dinamometre ile gerçekleştirilmiştir. Kesme kuvveti bileşenlerinin tahmininde YSA yöntemi kullanılmıştır. Sonuç olarak, Monel 400 alaşımının tornalanmasında en düşük kesme kuvveti bileşenleri 0,4 mm kesme derinliğinde, 110 m/dak kesme hızında ve 0,05 mm/dev ilerleme miktarında Fz:227,48 N, Fy:154 N ve Fx:99,16 N ölçülmüştür. YSA yöntemini ile tahmin edilen kesme kuvveti bileşenleri ile deneysel sonuçlar incelendiğinde YSA yöntemini ile yapılan tahminlerin yüksek doğruluk içerdiği görülmüştür.

“…The optimal outputs were observed at the least cutting speed (70 m min −1 ) and feed rate (0.06 mm per tooth). Akgün et al [6] also studied the turning of AISI H13 steel using coated tools and the resulting cutting forces, surface roughness, cutting temperature, and power consumption. Other authors have reported the main turning parameters affecting machined components.…”

Medium carbon AISI 1045 steel is a hard to machine material attractive to the automotive and construction industries due to its high strength and excellent heat resistance. Finite element method (FEM) is used in this study to obtain the optimal parameters for turning AISI 1045 steel. The simulation data is obtained and analyzed using an L16 Taguchi orthogonal array (TOA). Three input parameters: cutting speed (A), depth of cut (B), and feed rate (C), and three responses: cutting forces (Cf), maximum interfacial temperature (Tmax), and maximum principal stresses (σmax) are considered and analyzed using analysis of variance (ANOVA). The optimal conditions obtained are 60 m min−1 for A, 0.3 mm for B, and 0.4 mm rev−1 for C. The depth of cut and feed rate contribute the largest to the Cf (80.98%) and Tmax (38.56%), respectively. All the parameters contribute approximately equal toward the σmax. Comparison between the FEM values and literature experimental data shows that FEM can be used to predict optimal turning parameters with differences of ≈5%. This study gives a reference prediction model for the optimal machining parameters of medium carbon AISI 1045 steel and other related materials, which can be used, alongside experiments, to reduce the overall machining costs.

“…Results indicated that cutting forces, the degree of cutting heat, and the life of the cutter significantly affect the tool material, wear, and milling parameters 24 . Concurrently, some researchers focused exclusively on how milling parameters influenced cutting forces, temperatures, and tool life 25 . Additionally, under different machining conditions, the wear on titanium, aluminum, and nitrogen-titanium-nitride-coated carbide tools, as well as the deposition from physical vapor, were examined 26 .…”

TC21 alloy is a high-strength titanium alloy that has been gaining attention in various industries for its excellent combination of strength, toughness, and corrosion resistance. Given that this alloy is hard to cut material, therefore this study aims to optimize the process parameters of Turing this alloy under different conditions (i.e. as-received alloy, and heat-treated alloy). The L9 Taguchi approach-base orthogonal array is used to determine the optimum cutting parameters and the least number of experimental trials required. The achievement of this target, three different cutting parameters are used in the experimental work; each cutting parameter has three levels. The cutting speeds are chosen as 120, 100, and 80 m/min. The feed rates’ values are 0.15, 0.1, and 0.05, mm/rev, and the depth of cut values are 0.6, 0.4, and 0.2 mm. After applying three steps of heat treatment (First step: is heating the sample to 920 °C for 1 h then decreasing to 820 °C also for 1 h, second step: cooling the sample to room temperature by water quenching (WQ), the third step: holding the sample at 600 °C for 4 h (Aging process)). The results revealed that the triple heat treatment led to the change in the microstructure from (α + β) to (α + β) with secondary α platelets (αs) formed in residual β matrix leading to a decreased surface roughness by 56.25% and tool wear by 24.18%. The two most critical factors that affect the tool insert wear and surface roughness are the death of cut and cutting speed, which contribute 46.6% and 46.7% of the total, respectively. Feed rate, on the other hand, has the least importance, contributing 20.2% and 31.9% respectively.
