Experimental Research on Turning Ni-Based Superalloy with MQL Using Organic Alcohols

Abstract:

The machinability of Nickel-based superalloy GH4169 is poor. The traditional method to machining is to apply cutting fluids with the active additives, which, however, cause environmental pollution and health problems. In this paper, the MQL using organic alcohols, instead of cutting fluids, was applied on turning for the aim of green cutting GH4169. The effects of MQL, wet and dry cutting on cutting force and the chip deformation have been examined with coats carbide tools YBC251. The results of experiments indicated that the application of MQL produced lower cutting force with about 20 percent reduction compared to dry cutting, and it is advantageous in chip curl. The research results show that clean production was achieved in metal cutting associated with MQL using alcohols for cooling and lubricating.
