New design concepts of gas turbines are mainly based on increasing operational efficiency, reliability and environmental compatibility. For this reason, advanced classes of materials and manufacturing processes should be employed to meet the desired criteria. In the present investigation, efforts have been made to study on effective phenomena during milling of a TiAl alloy and to improve the machining process using MQL condition. To do so, surface roughness and microstructure of machined work-piece moreover to changes in cutting forces are studied. Experiments were designed using Taguchi method in 4 levels. Also, the machining mechanisms in Titanium Aluminide alloys were fully evaluated and discussed. Results show that by using optimized MQL condition for milling of TiAl alloy, 10 to 30 percent decreasing in cutting forces and a more controlled machining affected zone in microstructure could be achieved with no significant change in surface roughness.
