Selection of any casting alloy is dependent on a wide variety of factors such as casting process, service requirement and economy of processing viz. weldability, castability and machinability. Out of these, machinability plays an important role in the selection of material for its commercial exploitation. In general, more than 80% of the manufactured parts are machined before they are ready for use. Thus machinability of a material controls significantly its economy in various applications. In this paper, machinabilty is evaluated by studying various data/parameters of Al alloy (A-390) such as cutting forces, tool tip interface temperature, surface finish and power consumption during turning at different cutting speed, depth of cut and feed rate. In this study, Al-Si alloys with different composition were subjected to machinability testing by varying the cutting speed, depth of cut and by keeping feed rate constant.
