  • Evaluation of friction coefficient during machining with the assistance of alternative lubrication systems [Elektronski vir]
    Sterle, Luka, strojnik ; Pušavec, Franci ; Kalin, Mitjan
    Modern trends in machining lean towards the use of dry machining processes, or in alternative cooling-lubrication systems such as Minimum Quantity Lubrication (MQL), cryogenic or high pressure ... systems. High heat generation is critical for the quality of workpiece surface, tool life and energy consumption. Lubrication in the cutting zone is an effective way to reduce the generated friction and consequently heat. Solid lubricants have proven to be an effective way in reducing the friction in mechanical contacts. The most acclaimed substances include recently synthesized graphene and molybdenum disulphide. Also, their application in the machining processes can provide the reduction of the friction in the cutting zone, which consequently results in the prolonged tool life, increased surface quality, higher productivity and economically viable process. Different cooling lubrication techniques were tested by evaluating their influence on the coefficient of friction by the use of special tribometer, designed for high contact pressures. This work thus shows the potential of solid lubricants for improving machining performance.
