These variables govern the economics of machining operations. Therefore, the attempt has been made to carry out an experimental investigation by using Taguchi technique mainly to find and correlate the technological factors to the economics of machining process. The Taguchi method is systematic application of design and analysis for experiments. It is an effective approach to produce high quality products at relatively low cost. Therefore Taguchi method is used to investigate the multiple performance characteristic in the turning operation. The paper work deals with experimental investigations carried out to optimize mach-inability of commercial Al-7050(Aluminium) and to obtain optimum process parameters. The experiments will be carried out taking Al-7050 as the work piece material with carbide tool of various nose radius in the turning operation on CNC lathe machine. Levels of cutting speeds, depth of cuts, feed rates and nose radius will be selected as the most important parameters which affect machinability according to the Taguchi's Method. The Taguchi's orthogonal arrays will be employed to achieve the objective The Taguchi's Orthogonal array based on DOE (Design of Experiments) is one of the important techniques, which is used for optimization of process parameters of CNC. The L9 orthogonal array has been used to conduct the experiment for the material considered in this study. The response variables measured for the analysis were the Surface finish, Material removal rate, and machining time. At last confirmation made is considerable effort to simplify the methods of application of the technique and analysis of the results. However, some of the advanced concepts proposed by this require careful scrutiny. Therefore theme of our project is:-"Things should be as simple aspossible, but no simpler."-Albert Einstein
