Machining is usually the final stage of product development and can be performed by using conventional as well as non conventional machining methods. In present research work machining using CNC turning operation is performed on two materials used in product development, first material is (MS) mild steel and second is EN-31 (steel) which are frequently used in small and large scale business enterprises. The design of experiment table is set by using mixed Taguchi method and total 18 experiments were performed on CNC lathe machine. Response variable is selected which is material removal rate (MRR). L18 Mixed Taguchi array based experiments were conducted in CNC Supertech 6.2 turning centre using carbide insert CNMG 120408. The individual and interaction effects of cutting speed (v), feed rate (f) and depth of cut (ap) on MRR. Non-Traditional optimization technique taguchi is used to find the optimum parameters in turning of MS and EN-31.
