Inconel 718 is the most widely used in the aerospace industries, especially for gas turbine hot section components. Titanium alloys, on the other hand, have very high strength-to-weight ratio making them very suitable for aircraft engines and airframe manufacture. They account for 30% of the total engine mass in commercial and 40% in military projects. However, both these strategic materials have poor machinability, as a result of which they have dominated the major research interests in metal cutting industries in the past decades. One of the techniques to improve machinability is the use an...

The conventional induction heating method, used for heat treatment of parts has been customized as a novel method for heat assisted machining of metallic materials. This method is very clean and of low cost compared to laser heating. The method is especially applicable in milling operations with high width of cut, which a single laser can not cover and there is a need of employing multiple lasers. Heating time is very short and only the skin of the work piece is heated and removed during machining. Cutting forces are low due to lower yield strength of the materials at elevated temperature,...
