Dry hard turning has become an alternative machining process to grinding due to its ability to increase material removal rate, reduce production costs, and enhance of material properties.
However, hard turning has several issues such as high temperatures at the tool-chip and tool-workpiece interfaces which are affecting negatively on the surface integrity of the machined parts.
This is due to their high strength and wear resistance properties.
Conventional cutting fluid plays an important factor in improving machinability.
Recent decades, dry cutting is becoming more and more popular due to several benefits such as increase material removal rate, reduce production costs, and enhance of material properties.
