英文摘要： The following achievements have been gained on the research of systematical methodology to precision design and quality control for remanufacturing engineering: the principle and technical realization way of the statistical matching technique and the statistical selective assembly technique, the principle and technical realization way of coordinate control for assuring fit quality based on the batches of mating parts. The uncertainty of traditional manufacturing model can be turned into predictive certain information via using the inspection information of the batches of mating parts and statistical tolerance technique in those new methodology. Thus, the assembly precision can be improved and production cost can be reduced, which provide a guideline to the precision design for mating parts in manufacturing and remanufacturing engineering. The application software for design personnel has been developed as the technical supports for the statistical matching technique and the statistical selective assembly technique. An operation model for the remanufacturing enterprise alliance of machine tool and its realization line are presented based on the research and summarization to current status of remanufacturing enterprises of machine tool. The rapid comprehensive inspection, statistical analysis and grouping and adjudging techniques based on the features of typical remanufacturing components have been developed, and substantial progress and results have been gaind in the following research areas: the fast inspection method for sizes and shapes of hole and shafts surfaces, the measurement and quality evaluation system based on digital image processing for the micro hole surface, the non-disintegration detecting method for the wear of engines. A systematic method for remanufacturing-oriented precision design and quality control and resolvent plans of precision realization and quality assurance for typical remanufacturing components have been presented based on the above efforts, and it provide technical supports for the development of Chinese remanufacturing industry with lower costs, high quality, high benefits and effectiveness.
