Methodology of Process Oriented Dimensioning of Cooling Lubricant Pressure and Volume Flow for Increasing Energy Efficiency

In machining processes, especially when cutting difficult to cut materials such as nickel based or titanium alloys, the cooling lubricant supply strategies are often based on empirical knowledge. Notably, supply pressure and volume flow are key parameters which can be adapted even though they are partially interdependent. Mostly, these parameters are set too high to assure process stability, resulting in unnecessary energy and cooling lubricant consumptions. Within this paper, a methodology for dimensioning the necessary cooling lubricant supply and pressure is presented. In order to increase energy efficiency, the cooling lubricant supply pressure and volume flow will be adapted corresponding to the cutting process.
