摘要：

To overcome bottlenecks of insufficient heat capacity for atomizing air carrying nanofluids in grinding zone, a new process coupled with cryogenic air and nanofluid minimum quantity lubrication was proposed. A finite difference model of temperature field was established. Temperature fields of grinding zone with three cooling methods such as cryogenic air, nanofluid minimum quantity lubrication, and cryogenic air nanofluid minimum quantity lubrication were numerically simulated. The results show that cryogenic air nanofluid minimum quantity lubrication has the strongest heat transfer capacity, followed by cryogenic air, and nanofluid minimum quantity lubrication is the weakest. Moreover, the temperature field of surface grinding was verified under three cooling method experiments with Ti-6Al-4V as workpiece. The model error is less than 5%, which verified accuracy of the theoretical model. © 2021, China Mechanical Engineering Magazine Office. All right reserved.
