Poor surface quality and rapid tool wear are the main problems in micro-cutting of Inconel 718. In this study, a novel hybrid machining method named laser-induced oxidation assisted micro-milling is proposed to solve the aforementioned problems. A loose oxide layer and a relatively flat sublayer are formed on the material after laser irradiation. Under optimized laser parameters with a scanning speed of 1 mm/s and an average laser power of 4.5 W, the thicknesses of the oxide layer and the sublayer are 24 and 18 μm, respectively. The influence of cutting parameters on milling force, surface roughness, surface quality, and top burr size is studied in detail. Cutting force and thrust force in the proposed hybrid machining process are lower than those in the conventional micro-milling. Results show that for the investigated range of parameters, the optimal feed per tooth and depth of cut in the hybrid process are 3 μm/z and 3 μm, respectively. When using the optimal parameters, the surface roughness of the machined slot bottom is 108.5 nm. The top burr size on the up-milling side and the down-milling side is 26.8 and 36.2 μm, respectively. In addition, the tool wear mechanism is coating delamination in hybrid process, whereas chipping, coating delamination, tool nose breakage, and adhesion are the main tool wear mechanism in the conventional micro-milling. For the same amount of material removal, the proposed hybrid process can decrease the tool wear and enhance the service life of the micro-end mill as compared to conventional micro-milling.

Abstract This paper presents the results of comparative evaluation of soybean oil based MQL oil flow rates at 10, 30, 50, 70, and 90 ml/h with emulsion flood coolant (EC) at 1200 l/h as a benchmark in face milling of Inconel 718 using coated carbide inserts. Resultant cutting force, tool wear/ mechanism, and surface roughness are the machining performance parameters analyzed. The results show that MQL oil flow rate at 70 ml/h gave the least tool wear comparable to that of EC, while 10 ml/h gave the highest tool wear. Also, 70 ml/h gave the lowest resultant cutting force among all MQL flow rates. Increasing soybean oil-based MQL flow rate improves surface roughness and reduces tool wear by providing enough thin lubrication film but also leads to an increase in chip affinity and formation of large built-up-edges (BUEs) as the MQL flow rate reaches 90 ml/h. At lower soybean oil-based MQL flow rate, tool wear mechanism is predominantly abrasion due to large surface friction, while at higher soybean oil-based MQL flow rate, tool wear mechanism is adhesion leading to excessive BUEs. Soybean oil-based MQL flow rate at 70 ml/h is recommended when face milling Inconel 718 and is demonstrated to be a potential replacement of EC for machining difficult-to-cut metal.
