英文摘要： The theory about the evaluation of dynamic state and performance of Numerical Control machine tools based on built-in sensors measurement has been carried out for high-speed high precision large scale machine tools. The approaches for acquiring and handling the machine tool status information were proposed. The relationships between the status information and the precision and faults were studied, and the performance degradation, faults occurrence and development, and the device service performance evolution law were revealed, so the performance estimation, work status monitoring and fault diagnosis of machine tools can be realized. The relation of relative servo control parameters, such as displacement, speed and acceleration of the feed axis with the dynamic contour errors, such as circle error, corner error, etc.，were also studied, and the approaches of error separation and tracing for multi-axis machine tools were proposed,the measurement and analysis system of dynamic characteristics for NC machine tools has been developed, which provides the theory and technical support for the dynamic error analysis, compensation and adjustment of high speed high precision multi-axis NC machine tools.
