From customers viewpoint quality is very important because the extent of quality of the procured item or product influences the degree of satisfaction of the consumers during usage of the procured goods. Therefore, every manufacturing or production unit should concern about the quality of the product. Apart from quality, there exists another criterion, called productivity which is directly related to the profit level and also goodwill of the organization. To achieve maximum advantage in producing a good quality product, a good cutting tool is required. This paper aims at finding out the best cutting tool among the commonly used tools used in lathe machines for various operations. The different tools used are HSS(S-400), silicon carbide and tungsten carbide. Control chart technique is being implemented to find the best cutting tool on the basis of cutting forces exerted by the tools.
