Research on data acquisition and database-building technology based on highend CNC machine tool

High-end CNC machine tool is the main production equipment in the modern manufacturing industry, and its stability and reliability on operation state is directly linked to the machining accuracy and efficiency. In order to guarantee effectively the reliable stable and safe operation, the test study is conducted to the data acquisition and database based on high-end CNC machine tool. In this paper, the study of high-end CNC machine tool is focused on building the condition monitoring and test platform with the typical functional components. The method of data acquisition is presented, knowledge base and knowledge model are designed, the test platform of remote network data acquisition is built and real time data will be transferred to different client. A key technology is presented to reveal the dynamic performance of failure development and accuracy degradation mechanism, and the influential factors leading to failures.
