Nickel-titanium (Nitinol) superalloy is one of the most desirable shape memory superalloy due to its distinguished mechanical properties such as good corrosion resistance, shape-memory effects and high ductility and high mechanical strength. However, nitinol is often called as a difficult-to-cut material because of its high hardness and shape-change problems during machining. Ultrasonic Assisted Drilling (UAD) is one of the recent techniques that facilitate the drilling of these kind of difficult-to-cut materials providing ultrasonic frequency and low amplitude vibrations to the process. Minimum Quantity Lubrication (MQL) is environmentally friendly and economical in comparison to flood cooling in metal cutting, especially in machining difficult-to-cut materials. In this study, combined application of UAD and MQL is used in machining nitinol. Preliminary results showed that the use of UAD and MQL together is highly promising to facilitate the machining process of nitinol.
