机械标准与产品设计偏差关联性研究及其质量控制策略优化

摘要：

【目的】通过分析机械标准与产品设计偏差的关联性，提出针对性的质量控制策略的优化方案。【方法】构建机械标准参数（公差、材料强度）与设计偏差的量化模型（R2=0.95），提出动态公差优化策略，降低企业产品的不合格率。【结果】标准和设计偏差之间存在着显著的相关性，其关联程度对产品质量具有重要影响。在实践中，实施公差优化策略后，某企业产品不合格率从8.2%降至3.5%，有效提升了企业的生产效率和市场竞争力。【结论】对于加强标准执行、改善产品设计及提高质量管理水平具有重要的理论意义和实践价值。

Abstract:

[Objective] By analyzing the correlation between mechanical standards and product design deviations, this study aims to propose an optimized quality control strategy. [Methods] A quantitative model (R²=0.95) was constructed to link mechanical standard parameters (tolerances, material strength) with design deviations, and a dynamic tolerance optimization strategy was proposed to reduce the nonconformance rate of enterprise products. [Results] There is a significant correlation between standards and design deviations, and the degree of this correlation has a significant impact on product quality. In practice, after implementing the tolerance optimization strategy, the defective rate of a certain enterprise’s products decreased from 8.2% to 3.5%, effectively enhancing the enterprise’s production efficiency and market competitiveness. [Conclusion] This research has significant theoretical and practical value for strengthening standard implementation, improving product design, and enhancing quality management levels.
