In present scenario CNC turning operation plays a vital role in metal based manufacturing industries. Therefore selection of optimum machining parameters, Tool geometry and cutting condition etc. for the variety of materials is an important and complicated task for the manufacturing industries in providing best quality at less cost to the customers. In this research work CNC turning operation is carried out using L9 Taguchi orthogonal arrays on Naval brass C360 coated carbide insert and influence of CNC turning process parameters like Cutting Speed, Feed and Depth of Cut are analysed for two output objectives like material removal rate and surface roughness. The optimum sets of turning process parameter as well as combined effect of considered response are estimated using Taguchi technique application. In this analysis it is found that depth of cut has the largest effect on metal removal rate and feed rate has the largest effect on the surface roughness.It can be observed that depth of cut has the largest effect on metal removal rate and feed rate has the largest effect on the surface roughness of C360 brass by turning on CNC. The optimum turning condition for material removal rate isspindle speed (1600 rpm), feed rate (0.20 mm/rev.) and depth of cut (0.8 mm). The optimum condition for surface roughness is spindle speed (1400 rpm), feed rate (0.20 mm/rev.) and depth of cut (0.2mm).
