Experimental Investigation on Green Cutting GH4169 with Ionized Air Cooling and Lubricating
The machinability of Nickel-based superalloy GH4169 is poor, the traditional methods to machining is application of cutting fluids with the active additives which will cause environmental and health problems. In recent years, environmental concerns call for the reduced of cutting fluids in metal machining. The green manufacturing techniques are to be investigated to achieve this objective. In this paper, the ionized air was applied instead of cutting fluids for the aim of green cutting. The effects of ionized air on cutting force, cutting temperature and chip formation have been examined in turning of GH4169 with carbide tools K20. The results of experiments indicated that application of ionized air produced lower cutting force and cutting temperature, the values were reduced about 7 percent and 9 percent compared to dry cutting respectively, and it is advantage in forming acceptable chips. The research results show that clean production was achieved in metal cutting associated with ionized air cooling and lubricating.
