The 18th Life Cycle Engineering Conference of the International Academy for Production Engineering (CIRP, The International Academy for Production Engineering) proposed a modular energy consumption modeling method for the monitoring of energy consumption of mechanical processing equipment, which provides a basis for energy monitoring of mechanical processing equipment. Methodological support; Kordonowy of the Massachusetts Institute of Technology proposed a model for calculating the energy efficiency of machining equipment based on rated power, using statistical methods to divide the energy consumption of machining equipment into variable energy consumption and fixed energy consumption, and Using this method, a statistical model of energy consumption was established for various types of mechanical processing equipment; domestic research on this aspect is mainly due to the fact that Liu Fei proposed in the early years that there is still load loss in the mechanical processing process, that is, the transmission system and motor caused by the load. additional energy loss; Liu Gaojun et al. proposed a human-computer interactive machining state discrimination method, but this method requires real-time human operation, and it is inconvenient to apply in the workshop. Carried out relevant research on energy demand modeling of mold and mechanical processing processes and carbon emission calculations in the production process of product workshops
