As one of the five major projects of "Made-in-China 2025",the "Green Development Project" demands higher and higher efficiency and energy saving in the production of mechanical processing industry.It clearly requires the manufacturing industry to change from the extensive mode of "large consumption of resources and energy,high emission of pollutants" to "green manufacturing",and especially puts forward the idea of improving energy efficiency.Gear is one of the basic transmission parts in industrial production,and the demand is increasing.Hobbing as the most widely used gear processing method in mechanical manufacturing industry,creates huge wealth and consumes a lot of energy.In view of the current situation of high energy consumption and low efficiency in hobbing manufacturing process in China,it is a reasonable choice for the sustainable development of gear manufacturing industry to study the important laws of reducing energy consumption of hobbing machine tools and the methods of improving machine tool efficiency.This paper is funded by the national key common standards research project for green manufacturing in important areas "Research on Key Technologies and Standards for Energy Efficiency Detection and Assessment of Manufacturing/Production Process in Discrete and Process Industries"(No.2017YFF0207903)and the Ministry of Information Technology Green Manufacturing System Integration Project "Construction and Integrated Demonstration of Green Design Platform for Metal Cutting Machine Tools"(No.20165626).The optimization method and support system of CNC hobbing process parameters are studied,which can provide theoretical reference for energy saving and emission reduction of gear manufacturing enterprises in China and improving the efficiency of CNC hobbing process.Therefore,it has important research significance.Firstly,the energy consumption characteristics of CNC hobbing process are systematically analyzed,and the energy consumption function of CNC hobbing process is constructed based on the analysis of the time consumption characteristics of CNC hobbing process.Then,the energy consumption model of CNC hobbing process is obtained by non-linear regression fitting on the basis of the energy consumption characteristics analysis,and the reliability of the energy efficiency model is carried out.The verification.Secondly,a process parameter optimization model with the objective of minimizing the energy consumption and the processing time of hobbing is established,and the model is optimized based on imperial competition algorithm,and the typical numerical control hobbing process is used to optimize the parameters.The influence between cutting parameters and energy consumption and process time is analyzed.Thirdly,based on the model and method of CNC gear hobbing process parameter optimization for high efficiency and energy saving,the CNC gear hobbing process parameter optimization support system is developed,and integrated with Siemens 840 DSl NC system.The general framework,workflow and main function modules of the energy consumption optimization support system are introduced.Finally,the energy consumption optimization support system of CNC hobbing process parameters is applied in hobbing workshop.The implementation environment and configuration of CNC hobbing workshop support system are introduced.Taking typical CNC hobbing process in hobbing workshop as an example,the application is carried out,and the practicability and reliability of the system are verified.
