“…Studi yang dilakukan oleh Shalina Sheik Muhammad dkk ialah pengaruh gaya pemotongan permesinan end milling pada material baja AISI 4340 dimana kondisi pendinginana kering dan cryogenic (Muhamad et al 2019). Selain itu AISI 4340 juga diteliti tentang kemapuan mesin dalam pemotongan dengan memperhatikan jenis insert coated carbide (Das, Das, and Mandal 2017). Pada umumnya, material baja AISI 4340 sering dibahas proses pemotongan dengan memvariasikan parameter pemotongan permesinan pada CNC untuk mengetahui hasil pemotongan yang optimal (Lubis et al 2019).…”

Penelitian ini dilatar belakangi oleh perkembangan industri manufaktur dan dunia penelitian tentang permesinan. Selain itu, telah banyak yang melakukan studi tentang permesinan untuk mengetahui tegangan dan temperature secara eksperimen. Namun, masih sedikit yang membahas tentang analisis tegangan dan temperature menggunakan metode elemen hingga secara simulasi. Tujuan dari penelitian ini ialah Memodelkan dan menganalisis proses pemotongan orthogonal terhadap material AISI 4340 menggunakan pahat sisi pada perangkat lunak ABAQUS dimana output yang diketahui ialah nilai tegangan dan temperatur saat pemotongan. Adapun variabel permesinan dari penelitian ini ialah kedalaman pemakanan pada proses pemotongan (0.025 inch, 0.050 inch, 0.075 inch, dan 0.10 inch). Material sampel uji yang akan digunakan ialah AISI 4340 dan material pahat sisi yang digunakan ialah DNMG 120404 Carbide. Dari hasil analisis diperoleh nilai tegangan maksimum pada kedalaman pemotongan 0.10 inch sebesar 682,605 N dan tegangan maksimum terendah ialah kedalaman pemotongan 0.025 inch sebesar 197,503 N. Adapun nilai temperatur hasil pemotongan tergantung pada kondisi chips saat pemotongan.

“…Machining of hard steel materials (hardness between 45 and 68 HRC) at high speeds, feed rate, or depth of cut results in severe tool wear owing to high heat generation at the tool-chip interface, surface integrity issues of the workpiece, etc. (Awale and Inamdar, 2015), (Das et al, 2017). One such hard material widely used in the industrial front is the AISI 4340 steel, which is a type of Ni-Cr-Mo steel material (also known as medium carbon steel) and is known for its good toughness and strength (yield and tensile).…”

Machining of hard materials has been difficult and expensive because of poor surface smoothness, early tool failures, etc. When used in machining hard materials, such as medium and high carbon, cast steels, Inconel, and other alloys, nanomaterials combined with base fluids, such as water and oils, provide superior results in terms of surface finish and low cutting temperatures. To enhance our understanding of the field of machining and its applications, a comprehensive literature assessment on machining steels using nanofluids with/without the minimum quantity lubrication (MQL) approach was conducted. This research aims to investigate the performance of nanofluids (n-Al 2 O 3 , n-MoS 2 , and n-graphene) mixed with coconut oil in various proportions and injected into the tool-work interface using the MQL mist system. Output responses, such as surface roughness values, and cutting temperatures, were measured. The cutting temperatures were determined using an infrared camera and a k-type thermocouple, and the surface roughness was determined using a Talysurf surface meter. Cutting parameters, such as cutting speed, feed rate, and depth of cut, were maintained constant throughout the experiments. The experiments comprised a single factor (MQL fluid) with eight levels. Multiresponse optimization using grey relational coefficients showed that n-Al 2 O 3 and n-MoS 2 hybrid combinations with coconut oil yielded better results, i.e., higher ranks, compared with n-graphene mixtures in coconut oils. The experimental findings demonstrated that nanofluids outperformed pure coconut oil. Nano-Al 2 O 3 combined with coconut oil produced a superior surface finish, lowered the cutting temperatures, and ensured minimum chip thickness.

“…An analytical wear model formulated by Cao et al 42 considering the characteristics of intermittent grinding of a grinding edge, effects of wheel profile on the tool wear, and the number of active grinding edges. Das et al 43 observed that the production of continuous chips (flat) is obtained with a 1.2 mm nose radius at a cutting speed of 147 m/min at a 0.05 mm/rev feed rate. Adopting the CNC lathe machine Gundarneeya et al 44 used EN24 (817M40T) along with a cubic boron nitride tool for the hard part turning process.…”

AISI 4340 hardened steel is usually used in axle shafts, main shafts, gear, and couplings. Using multi-layer physical vapor deposition a coated tool, an attempt was made to optimize the input variables on precise turning on hardened AISI 4340 grade steel. The cutting speed, feed rate, and depth of the cut were the applied process factors in the dry-cutting environment. Furthermore, surface roughness (Ra), flank wear (VBc), cutting temperature ( T), and chip morphology were considered as technological responses. The Taguchi L27 standard orthogonal array with three levels and three factors was used in the experiment. Furthermore, scanning electron microscopy and energy dispersion spectroscopy were used to analyze tool wear and chip morphology characteristics. The relevance of the input process factors on the measured responses was determined using analysis of variance analysis. The feed rate was observed to have a dominant impact on the surface roughness in the trials. At an optimal parametric combination with 80 m/min cutting speed, 0.05 mm/rev feed rate, and 0.3 mm depth of cut obtained from the Taguchi-TOPSIS optimization method. The enhancement of the closeness coefficient was observed to be 0.2372. The generated second-order regression model was demonstrated to be of high significance. The strategy and outcomes of this research will help metal machining enterprises to augment manufacturing productivity when working with hardened steel.
