AB - China has the world’s largest machine tool consumer market, and its proportion of annual output of machine tools is still gradually increasing. As basic equipment of the manufacturing industry, the energy consumption of machine tools is significant. A lot of research has been done to model the cutting power, spindle power, and feed power of machine tools. However, many studies have shown that the fixed energy consumption of machine tools (generated by standby and auxiliary devices) accounts for a high proportion. This paper solves the problem of standby and auxiliary power modeling. The following work is done: (1) a new standby power empirical model is proposed, which distinguishes the standby power of CNC machine tool in weak and strong current states. Meanwhile, the new model reveals the influence of the intermittent working characteristics of the lubrication cooling device on the standby power, through deriving the power equations of the lubrication and cooling system (three stages are considered namely preheating, minimum theoretical oil supply period, and non-oil interval). (2) The new standby model is verified by experiments performed on a lathe, milling machine, and machining centers. Comparing with the existing standby power model, the new model is confirmed to be closer to the actual measurement curve of standby power, and avoids the standby energy consumption prediction error caused by using a single constant power value. (3) Through the analysis of the working principle and energy consumption of auxiliary functional components, the theory and empirical power equations of lighting, cutting fluid device, tool changer device, chip removal device power, and air blowing device are deduced, and also have been verified by experiments on three machine tools.
