中文摘要：	近年来，随着国家航天战略的深入推进，航天运载火箭的产业布局持续加强，对火箭的制造成本、产品质量与生产效率提出了更高要求。在这一背景下，化学铣切（以下简称“化铣”，Chemical Milling，CM）技术作为航天制造中的关键特种工艺，其重要性日益凸显。该技术通过化学溶液精确去除金属材料，实现复杂结构件的高精度成形，尤其适用于薄壁、异形及大尺寸火箭结构件的加工。然而，化铣工序繁多、流程复杂，涵盖前处理、涂胶、固化、刻型、化学腐蚀及检验等多个工序，任何一步出现偏差都可能导致零件尺寸超差或性能不达标。由于航天零部件具有价值高、精度要求极端严格的特点，一旦发生质量缺陷，往往造成巨额经济损失和进度延误。因此，实现化铣过程的精细化质量控制，是提升航天制造可靠性与经济性的重要一环。 本文以H公司运载火箭化铣生产过程为研究对象，系统开展了质量控制方法的研究。首先，基于对H公司企业概况及化铣生产历史问题的追踪与统计，从“人、机、料、法、环、测”六个维度全面识别生产中存在的质量隐患。借助鱼骨图工具，对这些因素进行系统性归因分析，明确各类问题的根源及其相互作用机制。基于FEMA方法，确定质量控制因素的优先级。在此基础上，针对化铣全流程制定了一系列针对性控制措施，从而构建起覆盖全过程的质量控制网。在落实上述控制措施后，本文进一步制定了持续改进的实施保障机制。通过一系列举措，H公司运载火箭化铣生产的质量稳定性显著提升。 本研究不仅为H公司运载火箭化铣生产过程提供了一套高效的质量控制方案，也可为同类航天制造企业的工艺管理提供可借鉴的工作路径，对实现高价值航天产品的化铣质量的可控具有一定的现实意义。
英文摘要：	In recent years, with the deepening of the national aerospace strategy, the industrial layout of aerospace launch vehicles has continued to strengthen, putting forward higher requirements on the rocket's manufacturing cost, product quality and production efficiency. Against this background, chemical milling (CM) and cutting technology is increasingly important as a key special process in aerospace manufacturing. This technology accurately removes metal materials through chemical solutions to achieve high-precision forming of complex structural parts, especially suitable for the processing of thin-walled, special-shaped and large-size rocket structural parts. However, CM processes are numerous and complex, covering multiple processes such as pre-treatment, glue coating, curing, shaping, chemical corrosion and inspection. Deviation at any step may lead to excessive parts size or performance failure. Because aerospace components have high value and extremely strict accuracy requirements, once quality defects occur, they often cause huge economic losses and progress delays. Therefore, achieving refined quality control of the CM process is an important part of improving the reliability and economy of aerospace manufacturing. This thesis takes the CM production process of H Company's carrier rockets as the research object and systematically conducts research on quality control methods. First, based on the tracking and statistics of H Company's corporate profile and CM production historical issues, the quality hidden dangers in production are fully identified from the six dimensions of "man, machine, material, method, ring, and measurement". With the help of the fishbone diagram tool, systematic attribution analysis of these factors is carried out to clarify the root causes of various problems and their interaction mechanisms. based on the Failure Mode and Effects Analysis (FMEA) method, the priorities of quality control factors are established. On this basis, a series of targeted control measures have been formulated for the entire process of CM and cutting, thereby building a quality control network covering the entire process. After implementing the above control measures, this article further formulates a continuous improvement implementation guarantee mechanism. Through a series of measures, the quality stability of H Company's carrier rocket CM production has been significantly improved. This study not only provides an efficient quality control solution for the production process of H company's launch vehicle, but also provides a reference work path for the process management of similar aerospace manufacturing enterprises, which has certain practical significance for realizing the controllability of the CM quality of high-value aerospace products.
