“…To determine optimum drilling parameters and analyze the effects of the determined drilling parameters on kerf angle and roundness error values, the Taguchi method was used, as it decreases experimental study costs and provides a systematic approach. The L16 (4 4 ) was selected as the most suitable orthogonal array [52].…”

In this study, carbon fiber-reinforced polymer (CFRP) composites with three different fiber orientation angles (M1: [0°/90°] s , M2: [+ 45°/− 45°] s , and M3: [0°/45°/90°/− 45°] s) were drilled (with and without pilot holes) on an abrasive water jet (AWJ) machine and the effect of the drilling parameters on the kerf angle (K) and roundness error (Re) of selected holes was investigated to determine quality characteristics. The first aim of the study was the single-objective optimization of drilling parameters for minimum K and Re individually. The second aim was the multi-objective optimization of drilling parameters for the simultaneous minimization of both K and Re. The Taguchi method was applied for single-objective optimization, while all steps of the Taguchi-based gray relational analysis were used for multi-objective optimization. Drilling experiments were performed using the L16 (4 4) orthogonal array. Four levels each for water pressure, stand-off distance, traverse feed rate, and hole diameter were selected as control factors. Analysis of experimental findings revealed that pilot drilling improved the kerf angle of the hole by 12.4% and the roundness error by 22.87%. Minimum kerf angle and roundness error were realized in the AWJ drilling of the M3 CFRP. The most effective parameter on kerf angle and roundness error in AWJ drilling of M1, M2, and M3 CFRP materials was water pressure (80.6%, 76.9%, and 73.8%, respectively), followed by stand-off distance (11.7%, 12.0%, and 13.5%),while other drilling parameters remained below 10%. The statistical evaluation and optimization results in this study can contribute to the evaluation of the AWJ machinability of CFRP composites.

“…The S/N ratio analysis utilizes three quality characteristics: “Smallest is best”, “Nominal is best”, and “Largest is best”. 11 For example, for the surface roughness, the lowest Ra value is desired. Therefore, in the optimization of surface roughness, the “Smallest is best” characteristic was selected.…”

“…In many studies, this method has been used to optimize the performance of cutting tools and parameters affecting surface roughness of the workpiece. 7,11,12 Asiltürk and Akkuş 13 optimized the surface roughness in AISI 4140 milling using the Taguchi method. The model they developed demonstrated that it could be used industrially to determine optimum cutting parameters.…”

Cryogenic treatment has been used in recent years to improve the performance of cutting tools. This study evaluated the machinability of a nickel–molybdenum-based super alloy using cryogenically treated (–80 ℃ and –145 ℃) ceramic inserts under dry turning conditions. Three cutting speeds (350, 400, and 450 m/min), three feed rates (0.1, 0.2, and 0.3 mm/rev), and a 1-mm fixed cutting depth were used in the turning tests. Experiments were conducted using the Taguchi orthogonal array L27 design. The factors affecting the surface roughness (Ra) were determined via analysis of variance. The effect of cryogenic treatment type (shallow and deep), cutting speed, and feed rate on surface roughness was investigated. Results of the analysis determined that the feed rate was the major parameter that affected surface roughness and that the deep cryogenic treatment was more effective. The regression analysis confirmed that the experimental results and the predicted values were within the 95% confidence interval. The most effective parameter affecting the surface roughness was feed rate at a contribution of 57.9%. The contribution of the cutting tool type to the surface roughness was 28.5%. The results obtained showed that the surface roughness can be optimized for turning the Hastelloy c22 super alloy with the Taguchi method.

Bu çalışmada kriyojenik işlem uygulanmış nikel esaslı süper alaşımın elektro erozyon işleme (EEİ) ile işlenme performansı araştırılmıştır. Bu amaçla ısıl dirençli nikel esaslı süper alaşıma sığ ve derin kriyojenik işlem uygulanmıştır. Deneylerde kullanılan parametreler deney maliyetini azaltmak için Taguchi L9 ortogonal diziyle tasarlanmış olup elde edilen sonuçlar istatistiksel olarak incelenerek kriyojenik işlemin yüzey pürüzlülüğü ve malzeme aşınma kaybı (MAK) etkisi araştırılmıştır. Her iki çıktı parametresi için en ideal parametrelerin belirlenmesinde ise Gray-Taguchi yaklaşımı kullanılmıştır. Yapılan çalışmanın sonucunda; yanıt tabloları incelendiğinde yüzey pürüzlülük değerleri için en etkili parametrenin malzeme ve vurum süresi için sırası ile A1B1, malzeme aşınma kaybı için ise A2B1 olarak belirlenmiştir. Anova sonuçlarına göre yüzey pürüzlülüğü için en etkili parametrenin %70,99 ile vurum süresi olarak, malzeme aşınma kaybı için ise % 71,66 ile malzeme olarak oluştuğu belirlenmiştir. Maksimum aşınma miktarı ve en düşük yüzey pürüzlülük değeri için gri ilişkisel derecesi hesaplandığında her ikisi için ideal faktörler birinci deney ile gerçekleştirilen parametrelerde oluştuğu tespit edilmiştir.
