Abstracts: In today's rapidly changing scenario in manufacturing industries, applications of optimization techniques in metal cutting processes was essential for a manufacturing unit to respond effectively to severe competitiveness and increasing demand of quality product in the market. A common method to manufacture part to a specific dimension involves the removal of excess material by machining operation with the help of cutting tool. Turning process is the one of the method to remove material from cylindrical and non-cylindrical parts. Optimization methods in metal cutting processes, considered to be a vital tool for continual improvement of output quality in products. This study focused in finding the optimum cutting speed, best surface finish, lower power consumption, good surface hardness, and better metal removal rate for materials there were other cutting parameters needed to be constant, such as feed rate, depth of cut and speed. Lathe machine was used to conduct the experiment. Selecting the wrong cutting parameter may lead to several negative effects. For example: high maintenance cost of the Lathe machine, poor surface finish of the work pieces, short tool life, low production rate, material waste and increase production cost.
