| CNC equipment is widely used in processing and manufacturing, but most are still stuck in stand-alone operation, decentralized management, and can not be centralized monitoring nowadays. Therefore, it wastes a lot of human resources and fixed assets investment, but also doesn't conducive to the quality management in production. In response to the above, combined with the reality of Hunan Oil Pump Co., Ltd., this paper mainly discusses the solutions for the production quality control system by CNC machine tools, the implementation of product quality control and trend analysis, in which case it increases the productivity of machine tools.This paper first introduced CNC machine tool production and monitoring system status, and gives the analysis on the needs of actual production-to-business system workshop. The system not only connects all the related equipments together, but also gives a suitable design of CNC machine tools for the production process and a multi-layered system. It also includes three partitions: field apparatus, workshop and factory. In each connection, we establish the network, and communication monitor system by using the industrial Ethernet. In the functional design, field apparatus will complete the transmission of data, workshop will complete the process of data acquisition,storage, control command, data analysis and processor transmission. The factory would be able to monitor the qualoty of products and the usage of quipments. On this basis, Delphi could be used as a development tool coding procedures of the system implementation.System in Hunan Oil Pump Co., Ltd. has been used in practice. Running results show that this system has the advantages in security, stability, etc. The enterprise improves the quality of automation, greatly reduces the labor intensity, improves the productivity of CNC equipment, implement the product quality control, creates a significant economiccal benefits after oprateing the system. |
