Abstract: A load-energy efficiency evaluation and monitoring method includes an actual part processing number and a theoretical part processing number of the numerical control machine tool within an evaluation period are obtained to calculate a loading performance of the numerical control machine tool. A waste time value and a standby power value of the numerical control machine tool are obtained to calculate a waste energy value of the numerical control machine tool. A single-part actual processing energy consumption is obtained and used, together with a single-part ideal processing energy consumption, to calculate the load-energy efficiency of the numerical control machine tool. A relationship model between the load-energy efficiency and the loading performance of the numerical control machine tool is built based on the obtained model of the load-energy efficiency of the numerical control machine tool and the obtained model of the loading performance of the numerical control machine tool.

Abstract: Disclosed is a method of accurately predicting energy consumption of an automatic tool change process of a multi-position rotary tool holder of a numerical control machine. In this method, automatic tool change durations at a plurality of groups of rotary tool position numbers are firstly measured and a calculation model of the automatic tool change duration is obtained by fitting. A basic module power of machine is obtained by collection and operation and a basic module energy consumption of machine is obtained by calculation based on the basic module power of machine and the automatic tool change duration. A steady state power of tool changer is obtained by collection and operation and further a steady state energy consumption of tool changer is calculated. A transient state energy consumption of tool changer is obtained by accumulating energy consumptions caused by all power peaks in the automatic tool change process of the numerical control machine. An energy consumption prediction model of the automatic tool change process is obtained according to the obtained basic module energy consumption of machine, the obtained steady state energy consumption of tool changer, the obtained transient state energy consumption of tool changer, thereby accurately predicting the energy consumption of the automatic tool change process of the numerical control machine and providing basic module support to the energy-saving optimization of machine.
