The Study And Realization Of The System For Assembly, Adjustment And Maintenance Of NC Machine

The ownership and the technical level of CNC machine tools are important symbols ofthe modern manufacturing strength of a country. CNC technology is a high and newtechnology in aspects of mechanical, electrical, instrumentation and hydraulic technology. Inthe production process, CNC machine tool alignment maintenance personnel is bond andbridge between the enterprise and the user, playing a role in the key links, such as assembly,commissioning, and testing; they also bear the service work. In the use of CNC machine tools,they are responsible for the performance adjustment of CNC machine tools and themaintenance and repair, the participation of the CNC machining process design andimplementation. Currently, for employees in this area, there exist some problems, for example,the average level of knowledge and skills, and lack of work experience. According to statistics,the country’s advanced CNC alignment and maintenance staff lack of about30,000people,which has seriously affected the healthy development of the CNC machine tool industry.Therefore, in order to improve the professional quality of personnel and to promote thedevelopment of the industry, it is an effective way to accelerate the specification of the careerstaff vocational training, develop a training system for meeting the job requirements, andequipping them with a more comprehensive knowledge of the mechanical, electrical,computer programming system.Firstly, this thesis analyzes works of CNC machine tool alignment maintenancepersonnel engaged, and according to the theoretical knowledge and skill requirements of thenational occupational standards, puts forward the requirements of the project, including theperformance of the system, the hardware configuration and software constitute.Secondly, based on the analysis of occupational standards and reality, this thesisillustrates the reasons for choosing the topic of FANUC CNC systems, and gives a detailedaccount of FANUC0i Mate-TC CNC system, and completes type-selection and hardwareconnections of spindle control system, feed control system and auxiliary control system. As tothe subject of realizing the installing and maintenance function for the entire system, thisarticle puts forwards the specific requirements and implementation methods for the structuraldesign and control system design of the machine tools.Once again, this thesis gives the design of system software, the draw of PMC control theflow chart, description of the use of the PC software; it also introduces the setting of CNCsystem parameters as well as the inverter parameters, the completion of the commissioning ofthe system.Finally, it gives a conclusion and presents outlook for further research.
