“…Hence to accomplish the desired features and productivity, the experimental run 23 trailed by the run of 22 and 24 (exclusion of 5 mm min −1 cutting feed) and the predicted optimal machining conditions and cutter nomenclature are as follows: Under Negative RRA cutter, the cutting feed and speed of 15 mm min −1 and 28.26 m min −1 to achieve lowermost cutting force requirement and surface roughness followed by the cutting feed and speed of 15 mm min −1 and 14.13 m min −1 under similar RRA cutter. From the above interpretation, it is confirmed that the Negative RRA cutter has invoke better observable features and productivity [20][21][22][23][24][25]. 3.6.…”

The Additive manufactured (direct metal laser sintering) samples has shown greater surface roughness which leads to reduce the functionality of the components. Additionally, the cutting force requirement and obtainable surface finish show the vigorous role during the slot milling process of many materials. In this study, the slot milling process has been conducted on the Additive Manufactured (AM) Inconel 718 alloy under numerous cutter nomenclature such as −7°, 0° and +7° in radial rake angle and machining circumstances such as a cutting feed (5, 15, and 25 mm min−1) and cutting speed (14.13, 28.26, and 42.39 m min−1) to analyze its impact on the cutting force requirement and surface roughness of AM Inconel 718 alloy through TOPSIS statistical tool. Through the above analyses, it is found that the cutter nomenclature plays a vigorous role in the cutting force requirement and obtainable surface roughness followed by the cutting feed and cutting speed, owed to the establishment of moderate strain strengthening and thermal soothing effect.

“…For example, the variation of microhardness of stainless steel 316L processed in AM, SM and HM techniques is displayed in Figure 22 . Subtractive processes, such as milling, provide higher value of microhardness due to the high temperature generated at chip-tool interfaces [ 203 ]. Higher microhardness observed in the parts produced by EDM process due to the deposition of hard thin re-cast layer on the workpiece surface [ 204 ].…”

Additive manufacturing (AM), an enabler of Industry 4.0, recently opened limitless possibilities in various sectors covering personal, industrial, medical, aviation and even extra-terrestrial applications. Although significant research thrust is prevalent on this topic, a detailed review covering the impact, status, and prospects of artificial intelligence (AI) in the manufacturing sector has been ignored in the literature. Therefore, this review provides comprehensive information on smart mechanisms and systems emphasizing additive, subtractive and/or hybrid manufacturing processes in a collaborative, predictive, decisive, and intelligent environment. Relevant electronic databases were searched, and 248 articles were selected for qualitative synthesis. Our review suggests that significant improvements are required in connectivity, data sensing, and collection to enhance both subtractive and additive technologies, though the pervasive use of AI by machines and software helps to automate processes. An intelligent system is highly recommended in both conventional and non-conventional subtractive manufacturing (SM) methods to monitor and inspect the workpiece conditions for defect detection and to control the machining strategies in response to instantaneous output. Similarly, AM product quality can be improved through the online monitoring of melt pool and defect formation using suitable sensing devices followed by process control using machine learning (ML) algorithms. Challenges in implementing intelligent additive and subtractive manufacturing systems are also discussed in the article. The challenges comprise difficulty in self-optimizing CNC systems considering real-time material property and tool condition, defect detections by in-situ AM process monitoring, issues of overfitting and underfitting data in ML models and expensive and complicated set-ups in hybrid manufacturing processes.

Stainless steel is one of the materials with excellent corrosion resistance, so it is widely applied in various fields such as the chemical industry, aerospace, power generation, and biomedicine. The environmental condition (neutral, acidic, salty, or basic) is the most important thing to be considered prior to choosing palpable stainless steel materials. In this study, the corrosion behaviors of stainless-steel type SS 316L under exposure immersions in salty and acidic environments using sodium chloride (NaCl) and sulfuric acid (H2SO4) solutions were investigated, by referring to a standard method of ASTM G31-72. Scanning electron microscopy (SEM) results revealed that the specimen in NaCl solution exhibited a darker color, and relatively similar shape of cracks are observed. In contrast, the specimen immersed in H2SO4 was observed to have a large diagonal crack. The corrosion rate of SS 316L immersed in NaCl was lower with a value of 0.4260 mpy, compared to that of H2SO4 which was 2.5141 mpy. The Vickers hardness test showed that the hardness value of NaCl immersion was higher than that of H2SO4, which was 6.34% and 1.94%, respectively. It can be concluded that the SS 316L is better used in a salty environment compared to acidic conditions, because the main function of SS 316L is to be able to withstand rust, one of which is caused by chloride compared to other types of stainless-steel.
