Abstract


In this paper, based on the analysis of the domestic and international development of the Roots blower to the development of reliable operation Roots blower foliar machining CNC system for the purpose of a systematic and detailed study of the Roots blower foliar CNC machining technology . The first chapter of the Roots blower works , features , applications, and development prospects , and discusses the significance of fan development of foliar processing , and then conducted a retrospective overview of the the foliar processing technology at home and abroad as well as CNC machining technology overview and its comments and concluded that the main content of this paper . Second chapter of the Roots blower leaf CNC machining theory discussed mathematical modeling analysis of the profile curve of foliar theory , given the trajectory equation processing tool ; discuss cutting the amount of processing the impact on the processing , and gives in the process , because the tool by the force of the shank occurs deformation tool running trajectory equations ; Finally the processing machine of the vibration generating mechanism of the analysis . Chapter of the overall structure of the CNC machining system are discussed , and discuss the various control programs , analyze its strengths and weaknesses , and to establish the ultimate control . Chapter PLC control system hardware design are discussed on the overall design of the system structure , control circuit design , transmission system design , the drive parameter choice , as well as anti-jamming circuit design . Chapter V of the PLC control system software design exposition introduces the overall structure of the system master software and thought control , and cutting direction control , knife control procedures such as described ; pulses and process control data calculation program ideas and algorithms discussed . Chapter 6 describes the design of the system debugging programs ; analysis and debugging process description , the last of the machining accuracy of the system is described . Chapter VII of the topics summarized .
