Manufacturing industries try to make high great products at decrease price to remain competitive within the market. The merchandise can be made the use of numerous production methods, including machining, etc. Milling is many of the most common machining processes used to make planar surfaces with faster material elimination and good floor first-rate. The vital objective of the technology of steel reducing is the solution of realistic issues associated with the green and particular removal of metal from work piece. It has been diagnosed that the dependable quantitative predictions of the numerous technological overall performance measures, preferably in the form of equations, are critical to broaden optimization techniques for deciding on slicing situations in procedure making plans. In this thesis experiments conducted to improve the floor end pleasant of AISI-316 work piece by way of the use of HSS and by using Taguchi‟s approach including QA8 orthogonal array. The test results were analyzed using smaller-the-better criteria for Signal-to-Noise ratio in order to optimize the process. The experimental results were analyzed, conformed and successfully used to achieve good surface finish on work piece materials.
