In the present research, the CNC turning operation has been pursued under three distinct media, i.e., dry, liq. CO2, and minimum quantity cooling lubrication (MQCL). In MQCL, the emulsion of coolant in water is mixed with liq. CO2 in a mixing chamber and the mixer is sprayed at the tool–workpiece interface. The setup is able to supply cutting fluid media at the cutting zone in various forms, i.e., flood coolant, droplet, or sprinkle form. With the help of a knob, the mixing chamber is able to control the flow of any of the cutting fluid, i.e., liq. CO2, MQCL, or MQL at the cutting area. After the experimental setup was developed, the experimental investigation was done with the setup. Material removal rate and chip morphology were compared at various cutting environments.
