Extreme Pressure Additives, Coefficient of Friction, S/N Ratio


This paper presents an attempt to study the performance of anti-wear (AW) and extreme pressure (EP) based oils used in deep drawing operations. Four ball tester was used for screening the performance of lubricants. Also an extreme pressure properties of deep drawing oils has been evaluated for its load carrying capacity. Using pin-on-disc machine, tribo-experiments were conducted employing various blends of AW/EP additives of different concentrations in mineral oil. Taguchi’s analysis technique was used, as a basis for systematic evaluation of friction coefficient under different operating conditions. A total of three lubricating blends were formulated and tested for varying concentration of vegetable base ester. On the basis of experimental results and S/N ratio analysis, ranking of the parameters has been done. This paper suggests a scientific approach for evaluation of commercially available lubricants.
