Friction is important in almost all the material removal operations for higher accuracy and surface finish. Depending on the application and the specifications of the final product, almost in all the mechanisms, lubrication properties contribute to the success or failure of the process. Depending on the application and the specifications of the finish product. In the present investigation the coefficient of friction is determined for several materials. The effect of friction on metal was studied by pin on disc wear testing machine. Cold rolled steel, Brass, titanium, Mild steel, Stainless steel and Teflon are considered in this work and the frictional force and coefficient of friction is considered for all these materials under several lubricants and it is analysed. The relation between the properties of lubricants such as flash point, coefficient of friction, density and density of the material for selecting the efficient lubricant is also investigated. The wear test was performed for the above-mentioned metals considering the lubricants and the wear rate were analysed. Castor oil performed well by reducing the coefficient of friction when compared to the other lubricants used in this experimental analysis
