Due to their extremely performant capabilities, super-alloys are gratefully acknowledged by mechanical designers to satisfy the requisites from the combustion chambers and other hot parts from the aircraft turbine. However, the high mechanical resistance and high chemical reactivity of heat resistant super-alloys (HRSA) lead to very aggressive machining operations where the tool life must be conveniently protected with cutting fluids. The novelty in this work lies in the idea of applying cryogenic cooling with MQL lubrication (CryoMQL) with CO2 as internal coolant to favor the integration of more environmental friendly machining systems. To prove the benefits from the novel technique, CryoMQL was compared with other lubri-coolant technologies. In this context, contour milling tests were carried out in Inconel 718.
