This study focuses on the machining of Nimonic80A, a difficult-to-cut super alloy. Friction during the turning process can lead to affect surface quality and chip shearing, which results in different chip shapes. Turning experiments were carried out under the three machining conditions of cutting velocity (70, 140, and 210 m/min), feed rate (0.1, 0.15, and 0.2 mm/rev), and depth of cut (0.5, 0.75, and 1 mm). The experimental design was established using a Taguchi L27 orthogonal array for both dry and nano-MQL lubricant conditions. Surface roughness, chip reduction coefficient, tooth height, and tooltip temperature were among the response characteristics of interest. Suspension of graphene oxide in rice bran oil was used in the study to produce and used as nanofluids for minimum quantity lubrication (nano-MQL). Furthermore, the addition of GO nanoparticles introduces a tribo-film effect that reduces friction tracks in the chips and enhances surface smoothness. Ribbon chips, short, long, tangled, and washer-type helical chips are among the chips created under the nano-MQL condition. The chip reduction coefficient increases with an increase in cutting velocity. It ranges from 1.46 to 1.95, the minimum chip reduction coefficient is achieved at high cutting velocity (210m/min) for all level of feed rate and depth of cut during nano-MQL machining. As a result of the NMQL environment, chips were created that were tightly wound and had few serrations, making them simple to handle and discard.
