Test Research on the Construction of Dynamic Performance Detection Platform for High-Grade Numerical Control Machines

High-grade numerical control machines have gradually become the major machining equipments in our Chinese modern manufacture and the scale of its manufacturing system is also precise and integrated and intelligentized day by day, in order to ensure the machine to achieve its function effectively, research on test will be needed to do to analysis the fault symptoms and reasons which effect machine machining accuracy. However, traditional test system cannot satisfy modern high-grade numerical control machines test study requirements. For this reason, this paper puts forward the technology research on the construction of dynamic performance detection platform for turn-milling complex processing center to provide a strong guarantee for detecting equipments´ machining conditions in real time and forecasting equipment failures accurately, which provide the modern test equipments for test research on the high-grade numerical control machines. Based on high-grade numerical control machines dynamic performance detection platform, this paper conducts a technology research on the effective acquisition test of data samples on typical functional parts of numerical control machines to improve machining precision of numerical control machines, and puts forward sample test acquisition method of operation condition of numerical control machines, and conducts the design of sample fault diagnosis knowledge base. The purpose of the research work is to provide test equipments to reveal high-grade numerical control machines dynamic performance, and another purpose of the research is to provide the key testing techniques for revealing the dynamic performance of fault occurrence and development and factors resulting in deterioration of precision.
