几何非接触式测量技术在汽车车身钣金件测量过程中,测量数据的再现性较差。文中通过不确定度分析与分离技术,找出影响非接触式测量重复性和再现性的原因,并通过相关测量规范的建立,有效地保证了非接触式测量的精度和再现性,并提高设备的利用率和使用范围。
Geometric non-contact measurement technology in the automotive body sheet metal measurement process, the reproducibility of the measured data is poor. In this paper, by uncertainty analysis and separation technology, find the reasons that affect the repeatability and reproducibility of non-contact measurement, and through the establishment of relevant measurement specifications, effectively ensure the accuracy and reproducibility of non-contact measurement, and improve equipment Utilization and scope of use.
