Cooling systems are used in machine tools e.g. for the cooling of the spindle, the drives, the cooling lubricant, the control cabinet and the hydraulic system. Cooling systems are one of the main consumers of energy of machine tools. This paper analyses and compares different decentral cooling systems with regard to their power consumption for an exemplary machining centre. To achieve this, the power consumption of the exemplary machining centre is analysed for different operating conditions. On the one hand a cooling system is analysed that from the perspective of energy efficiency represents state-of-the-art technology. And on the other hand a unit is examined whose energy consumption has been optimized. Besides power, displacement of tool centre point and further values as pressure, flow rate and temperature are monitored for the different machining conditions and cooling systems.read more

A systematic literature review on machine tool energy consumption
TL;DR: It is observed that the research focus has shifted towards micro level classification of machining energy including transient states and the use of micro analysis, energy benchmarking and standardization of energy assessment indices require more research.

Energy saving opportunities in direct drive machine tool spindles
TL;DR: In this paper, the authors carried out a comprehensive assessment of the energy saving opportunities linked to the introduction of direct drives solutions in machine tool spindle systems, and the identified models were used to estimate the energy savings that can be achieved substituting the traditional gearbox-based solution with the novel direct drive spindle.

Energy efficient machining of Ti–6Al–4V
TL;DR: In this article, the authors demonstrate a correlation between process power and cutting fluid demand represented by tool wear appearance, and show that optimized cutting parameters lead to energy savings of more than 40 percent at the working spindle.
