Multi-objective optimization of Abrasive water jet Machining parameters for Inconel 625 alloy using TGRA

Comparison of drilling of Inconel 625 by AWJM and WEDM

“…For this reason, the average roughness value obtained in this study is lower than that obtained in the literature studies. The values obtained in our study are closer to the data of Rana and Akhai (2022) and Sibalija et al (2021). Rana and Akhai obtained 2.31–2.33 Ra surface roughness and 0.79–0.80 kerf taper angle values by cutting Inconel 625 material with 1–2 mm standoff distance and 100–200 mm/min transverse speed machining parameters in the AWJM method (Rana and Akhai, 2022).…”

“…For this reason, the average roughness value obtained in this study is lower than that obtained in the literature studies. The values obtained in our study are closer to the data ofRana and Akhai (2022) andSibalija et al (2021). studies because the standoff distance value in this study is 2 mm.…”

“…Over time, it has been used for machining ferrous and nonferrous metals and even superalloys. It is recognized in the industry as a very effective method for machining many material groups (Rana and Akhai, 2022). Nickel-based superalloys are difficult to process by conventional methods because of their poor thermal conductivity, exposure to thermal and mechanical loads in the use of cutting tools, a deterioration in the microstructure that may cause plastic deformation or recrystallization, the morphology and orientation of the grains and tensile residual stress (Salinas et al , 2021).…”

“…It was reported that SOD, AMF and TS processing parameters contributed 79%, 7% and 14% to obtaining minimum kerf, whereas SR and kerf increased with increasing MRR. They suggested a 1 mm standoff distance, 300 gm/min abrasive mass flow rate and 200 mm/min transverse speed values for maximum performance in terms of MRR and SR (Rana and Akhai, 2022). Yuvaraj et al drilled small cooling holes in Inconel 625 superalloy with 0°, 10°, 20°, 30°, 40° and 45° inclinations using standoff distance (0.5, 1, 1.5, 2, 2.5 and 3 mm) and abrasive flow rate (200, 250, 300, 350, 400 and 450 g/min) machining parameters in the AWJM method to determine the effect of machining parameters on machining time, hole entry diameter and surface morphology.…”

“…(Rana and Akhai, 2022). A low traverse speed of 75 mm/min was used in this study, so an average of 2.293 Ra roughness and 0.976 kerf were obtained.…”
