英文摘要： This research is focused on synthetical mathematical model, efficient measurement, precise and robust modeling, network group control and real-time compensation of multi-errors for multi-axis CNC machine tools (up to five-axis). Consisting of geometric error, cutting force-induced error and thermal error,the synthetical mathematical model of multi-errors will be unified for all types of CNC machine tools. Through the proposed theories and methods ,i.e. the efficient laser measurement and identification of error elements based on vector-sequential-steps and combined-path-movement methods, three-dimensional placement for temperature sensors,combinations and modeling of geometric and thermal errors, and decoupling compensation for five-axis CNC, a cost-effective multi-error real-time dynamic compensation system can be developed. Along with the on-line auto-modeling software, the remote monitoring and correction of the error real-time compensation through network will be realized,so as to greatly improve the precision of machine tools,and establish a new system of error measurement,modeling and compensation theories and methods. The core technology with independent intellectual property rights will be promoted to domestic enterprises to improve their competitive strength in global markets,and the error compensation
