Dry electrostatic cooling (DESC) assisted machining is one of the green machining technologies that uses ionized air flow as lubricating and cooling medium in the machining process. The influence of discharge parameters on the efficiency of ion transport and ozone concentration in the DESC is experimentally researched. The results show that the efficiency of ion transport increases with the rising of the discharge current and air pressure, but decreases with the rising of the distance from the nozzle and the nozzle diameter. The tungsten electrode is used to obtain high ozone concentration with the nozzle diameter of 2-4mm, air pressure of 0.2-0.4MPa, and the distance from the nozzle within 0.5mm. Experimental research on the DESC assisted machining for hardened steel GCr15 shows that cutting force decreases by 7%-28%, tool wear reduces by 30-50%, and tool life is 1.5-3.3 times more than dry cutting. Better results are achieved when increasing the cutting speed.

“…Zhao et al [15] applied nitrogen-oil-mist as a cutting medium on the highspeed milling of Ti6Al4V and determined that tool wear can be effectively reduced in experiments. Several research conducted in Russia indicated that tool life is three times longer in the machining process of heatresistant alloy and high strength stainless steel with ionized air than that in dry cutting [16][17][18]. Han et al [19,20] used ionized air flow to cut titanium alloy Ti6Al4V and superalloy GH4169 instead of cutting fluids.…”

A long, quasi-homogeneous cold plasma jet was generated through a homemade cold plasma jet generating device. Friction-wear test and assisted cutting of Ti6Al4V were studied under air, nitrogen, and nitrogen cold plasma jet (NPJ) atmospheres. The friction coefficient under nitrogen jet was small, and the wear appearance was smooth at lowspeed friction. At high-speed friction, the friction coefficient under NPJ was the smallest, which declined by 70 % compared with that under air atmosphere. The scratches and adhesive traces on the friction surface were the lightest as well. The lubrication and cooling effects were not evident under low-speed cutting, whereas the NPJ enabled the radial force Fy and the average flank wear width VB to decrease by nearly 40-47 % respectively under high-speed cutting compared with the ones under air atmosphere. Results show that the NPJ assisted cutting has little influence on the surface roughness, residual stress, and work hardening of workpieces, while the machinability of Ti6Al4V can be effectively improved.
