N2 - Conventional cutting fluid is commonly used in the cutting process of iron-based superalloy. However, cutting fluid is easy to cause environmental pollution and cutting costs increasement. In this paper, turning experiments on superalloy GH2132 were carried out with three different coolants, namely, cutting fluid, liquid nitrogen (LN2), and liquid carbon dioxide (LCO2). The cutting force, specific cutting energy, surface roughness and cutting ambient air particulate concentration were analysed. The results show that, compared with cutting fluid, LN2 is more effective in reducing the cutting force. The specific cutting energy under LN2 is reduced by 25.3% at v = 40 m/min, ap = 0.3 mm and f = 0.1 mm/r. When the feed rate is 0.2 mm/r, the surface roughness under LCO2 can be reduced by 42.4% than the cutting fluid. In addition, the use of LN2 and LCO2 can reduce the concentration of PM2.5 by 64.1% and 81.7%, respectively.
