工单制程能力CPK分析数据集

该数据集适用于各类精密制造企业的产品制程质量评估工作，特别用于分析关键尺寸（如心厚）的波动情况，辅助制程能力判断。当“管控状态”为“已核算”时，可据此数据判断工艺是否稳定、偏移是否严重，是否存在批次异常等问题。该数据也适合用于横向比对不同规格型号、不同机台下的Cpk指标，进而指导工艺优化与人员操作改进，是过程能力评估与质量审核的重要数据基础。This dataset is applicable to product manufacturing process quality assessment for various precision manufacturing enterprises. It is specifically designed to analyze fluctuations of critical dimensions (such as core thickness) and assist in process capability evaluation. When the "control status" is marked as "calculated", this dataset can be used to determine whether the process is stable, whether the deviation is severe, and whether there are batch abnormalities and other related issues. It is also suitable for cross-sectional comparison of Cpk metrics across different specifications, models and machining equipment, so as to guide process optimization and operator performance improvement, serving as an important data foundation for process capability assessment and quality audit.
