摘要：
The remanufactured machine tool is assembled by reusing parts, remanufactured parts and new parts, and its assembly parts have more uncertainty and randomness. To ensure the consistency and reliability of remanufacturing machine assembly precision, a mathematical model of assembly process error transfer should be established to describe the error transmission and accumulation rules of remanufacturing machine assembly process quantitatively. The mathematical mapping relationship between the quality characteristics of the parts, the actual measurement results and the error sources of assembly process during the assembly process of remanufactured machine tool was proposed. An error flow model of the remanufacturing machine's assembly process based on state-space model was also proposed. The variation of part quality characteristics, feature measurement and adjustment deviation of the remanufacturing machine tool assembly process were quantitatively described. On this basis, the error flow correction function was proposed to realize the accuracy prediction, analysis and quality error correction of remanufacturing machine tool. By taking the assembly process of remanufacturing machine headstock as an example, the result showed that the assembly process error could be reduced by the proposed model and correction function effectively. © 2021, Editorial Department of CIMS.
