发动机曲轴尺寸检测分析数据

曲轴是汽车零部件中的一个重要零部件，曲轴的尺寸检测关乎到发动机的性能和寿命，因此在生产曲轴的过程中通常会对其尺寸进行检测，尺寸不合格零件也报废了，可以有效地检测出产品的质量是否达标，以确保产品的质量和安全性。本数据可以对曲轴尺寸的情况进行安全性评价，为厂家提供一个参考和技术支撑，让厂家提升生产工艺，减少不良率。1.数据采集:采集样品名称、检测项目、直径平均值、圆度度平均值、弯曲测量检测等信息;2. 通过对发动机曲轴的直径平均值测量、圆度平均值测量和弯曲度测量，获得曲轴相关数据的数值;3数据处理:筛选出发动机曲轴尺寸问题项检测结果，用于评估其曲轴的安全性，直径平均值偏差范围：49.99至50.01，圆度平均值偏差为0.015，弯曲度偏差范围为0.03，三项任何一项不合格及该曲轴为不合格，发动机曲轴尺寸问题发现率=发动机曲轴尺寸检出问题项次数/进行发动机曲轴尺寸检测的总数;4、数据应用: 发动机连杆尺寸问题发现率检测结果可以作为厂家生产依据，根据不合格率来改进生产工艺，减少不良率。

The crankshaft is a critical automotive component. Dimensional inspection of crankshafts is closely linked to engine performance and service life. Thus, dimensional testing is routinely performed during crankshaft manufacturing, with unqualified parts being scrapped. This process effectively verifies product quality compliance, ensuring overall product quality and safety. This dataset enables safety assessment of crankshaft dimensional characteristics, providing manufacturers with reference and technical support to optimize production workflows and reduce defect rates.
1. Data Collection: Collect relevant information including sample name, inspection items, average diameter, average roundness, bending measurement and other related metrics;
2. Acquire numerical data related to engine crankshafts via measurements of average diameter, average roundness and bending degree;
3. Data Processing: Screen inspection results for dimensional issues of engine crankshafts to conduct safety evaluation. The allowable deviation range for average diameter is 49.99 to 50.01, the allowable average roundness deviation is 0.015, and the allowable bending deviation is 0.03. A crankshaft is deemed unqualified if any of the three inspection items fails to meet the specified standards. The dimensional defect detection rate for engine crankshafts = (number of detected dimensional defects in engine crankshafts) / (total number of inspected engine crankshafts);
4. Data Application: The detection results of the dimensional defect detection rate for engine connecting rods can serve as a production reference for manufacturers, who can adjust their production processes and lower defect rates based on the unqualified product ratio.
