“…In EDM, the electro-thermal energy conversion principle is used, wherein the material is removed through the formation of a spark [91]. Dielectric materials (water-based, gaseousbased, hydrocarbon-based) were used during the EDM process to alter the sparking trend, thereby enhancing the performance of the machining process in terms of surface finish and MRR [22]. In addition, EDM is a noncontact machining process due to which the tool impression on the work material, tool vibration during machining, and mechanical stresses are eliminated [92].…”

Superalloys have gained prominence in recent years in various sectors, namely, spacecraft, marine, power, defense, vehicular and others, due to their ability to withstand high temperatures of up to 980 °C without deformation. Nimonics are Nickel-based superalloys usually known to be hard-to-machine materials due to their high strength at high temperatures, higher hardness, low thermal conductivity, and tendency to react with tool material. All these factors increase the level of difficulties in the machining of Nimonic superalloys. Numerous studies have examined various facets of machining of Nimonic alloys. This article summarizes the observation from 152 research articles to offer a reasonable engineering overview of the study of Nimonic alloys. An overview of Nimonic superalloys and their applications is given first. Then, various conventional and non-conventional machining processes, problems associated with multiple machining processes and methods to rectify the issues concerning the machining process have been reported. Thus, this summary will certainly help industrialists and academic researchers for further research work in machining Nimonic alloys.

“…Surface roughness was quantified using a surface roughness tester, circularity was measured using Quick Image, and the microstructure and chemical content were examined using FESEM and EDS. Pant et al [15,16] studied the machining of heat-treated Nimonic 80A alloy using the electric discharge machining process to understand the impact of machining parameters on superalloy materials. Singh et al [17] utilized WEDM (Wire Electric Discharge Machining) to machine Nimonic 80A superalloy and investigated various process parameters.…”

The need for the application of superalloys in aerospace industries in recent years has increased owing to its benefits such as extensive load-bearing capability under high temperatures. Hastelloy is one such superalloy that is extensively utilized in the aerospace sector because of its good corrosion and heat resistance among the other nickel-based superalloys. In this work, the investigation is conducted to understand the effects of input process parameters such as voltage, pulse off time (Toff), and pulse on time (Ton) on the response variables, namely Material removal rate (MRR), Tool wear rate (TWR), Overcut (OC), and Taper Ratio (TR) during micro-EDM of Hastelloy C276. For micro drilling the Hastelloy C276 material, a copper electrode with a diameter of 0.5 mm is utilized. To investigate the connections between the input and output characteristics, a technique known as the Response Surface Methodology (RSM), which is a collection of mathematical and statistical methodologies, is applied. The experimental runs are carried out with the help of the RSM-based Box-Behnken design (BBD). The experimental outcomes were computed, and ANOVA was used to identify the most influential variables. In addition, particle swarm optimization (PSO) was utilized to optimize the results, which were compared to the Response surface methodology approach. The outcomes of the PSO-optimized results revealed a strong correlation between expected and experimental outcomes over the RSM approach.

“…Geleneksel talaşlı imalat yöntemlerinden farklı olarak bu yöntemlerde temel işleme prensip, bir dielektrik sıvı ortamında takım ve iş parçası arasında temas olmadan meydana gelen elektriksel kıvılcımlar tarafından üretilen ısı ile şekillendirmedir [5]. İş parçasının yüzeyine boşalan kıvılcım, noktasal olarak erime ve buharlaşmaya neden olur ve küçük metal parçacıklarının iş parçasından kopmasını sağlar [6]. Elektro erozyon yöntemi ile elektriksel iletken, çok yüksek sertlik ve mukavemetli ve karmaşık geometrili malzemelerin kolaylıkla işlenebilmesi bu yöntemi modern imalat yöntemleri arasında seçkin bir noktaya getirmiştir [7].…”

Bu çalışmada, ferritik paslanmaz çelik malzemenin elektro erozyon ile işleme yöntemiyle işlenebilirliği araştırılmıştır. Deneyler boşalım akımı (A), vurum süresi (T on ) ve vurum bekleme süresi (T off ) olmak üzere üç farklı işleme parametresi kullanılarak Taguchi'nin L 9 ortogonal dizisi uygulanarak deneyler yapılmıştır. Belirlenen parametrelerin iş parçası işleme hızı (İİH), elektrot aşınma hızı (EAH) ve ortalama yüzey pürüzlülüğüne (Ra) olan etkileri incelenmiştir. Deneysel sonuçlara göre iş parçası işleme hızı, elektrot aşınma hızı ve yüzey pürüzlülüğü boşalım akımının artmasıyla birlikte artış göstermiştir. Ark süresinin artması ile İİH ve EAH değerleri artarken, elektrot aşınmasının azaldığı tespit edilmiştir. Ayrıca elde edilen deney sonuçları Taguchi tabanlı gri ilişkisel analiz yöntemi ile çoklu optimizasyonu yapılmıştır. Optimum işleme parametreleri, boşalım akım, vurum süresi ve vurum bekleme süresi için sırasıyla 6 A, 400 µs ve 100 µs olarak belirlenmiştir.
