cutting force of high energy efficiency milling cutter is an important indicator.Building the proper energy using up model of major cutting force of milling cutter and research the moving features of the energy consumption of the main cutting force of the milling cutter is of major significance for stable control of energy stream in the milling procedure and pickup of energy efficiency.The article is supported by National Nature Science Foundation of China "Multi-scale Coupling Mechanism of Nonlinear Friction Dynamic Wear of Energy-efficient Milling Cutter(51875145)" and the Nature Science Foundation of Heilongjiang Province of China of key project "The orderly multi-source evolution mechanism and key technologies of high energy efficiency milling of the basic components of heavy-duty machine tools(ZD2020E008)".With the target of achieving the valid command of the energy using up of the major cutting force of a high-energy-efficiency milling cutter,combined with milling processing examples,The study of the evolution characteristics of the energy consumption of the instantaneous main cutting force of the milling tool and its control method is carried out.The existing methods for solving the energy consumption of the main cutting force of milling cutters used the combined force of the main cutting force of each tooth of the milling cutter or the main cutting force of the milling cutter obtained through experiments,which disregard the inconsistency of the effect typicals among the milling vibration,cutter fang deviation and non-straight fang construction of milling cutter on the swift cutting conduct of each cutter fang,and the dynamic characteristics of the main cutting force and what is needed to be revealed is the dynamic characteristics of main cutting force energy consumption of each cutter fang and the milling cutter utilizing the way of cunning the instantaneous cutting border of the cutter fang cutting edge,utilizing the vary features of the instantaneous cutting speed vector and the instantaneous main cutting force vector of the cutter fang milling micro-element,the instantaneous main cutting force energy consumption distribution function of the cutter fang is structured to get the instantaneous main cutting force energy using up of the cutter fang and the instantaneous main cutting force energy using up of the milling tool.Forthputting the prompt main cutting force energy using up model of milling cutter,different characteristic time intervals in the whole cutting process are intercepted to reveal the evolution characteristics of the main profile bias of milling cutter,instantaneous cutting boundary of milling cutter tooth,the evolution characteristics of the energy consumption of the main cutting force of the cutter tooth and the energy using up of the chief cutting force of the milling cutter.The time-frequency characteristic parameters of the main cutting force energy consumption of the milling cutter were utilized to verified the energy consumption evolution characteristics of the main cutting force of the milling cutter.The results indicate that the computed result curves of the main cutting force energy consumption of the milling cutter has a high similarity with the experimental result curves,and the principle of the influence of milling oscillation,milling parameters and construction parameters of the milling tool on the energy consumption of the main cutting force of the milling tool can be identified by using the above model and method.Using response surface method,according to the single-factor response characteristics of the main cutting force energy consumption of the cutter tooth and the milling cutter,a response surface model of the main cutting force energy consumption of the cutter tooth and the main cutting force energy consumption of the milling cutter was constructed.It also builded the response side model of main cutting force energy using up of cutter fang,main cutting force vitality using up relationship of cutter fang,and main cutting force energy depletion of milling cutter.In the light of the results of the response side variance analysis and the vigor consumption response side of the principal cutting power of the milling cutter,it divulges the influence characteristics of various influence elements and their interaction on the energy consumption of the main cutting force of the cutter tooth,the energy consumption relationship of the main cutting force between the cutter teeth,and the energy consumption of the main cutting force of the milling cutter,which provide a basis for realizing the control of the instantaneous main cutting force energy consumption of the milling cutter.In the light of the noteworthy analysis results of the components effect the energy using up of the main cutting force of the milling cutter,the key control variables of the energy consumption of the main cutting force of the milling cutter are acquired.Getting the milling working efficiency as the constraint condition and the maximum correlation between the energy using up of the main cutting force of the milling cutter and its fang and the energy consumption of the main cutting force without milling vibration as the control objective,a control method of the energy consumption of the main cutting force of the milling cutter is proposed.Using this method,the design scheme of instantaneous main cutting force energy consumption of milling cutter is obtained,which also verified the effectiveness of the control method of instantaneous main cutting force energy consumption of milling cutter by experiments.
