The novel approach for holistic screw thread calibrations developed by the Physikalisch-Technische Bundesanstalt was published in 2019. A significant achievement has been made in order to meet increasing demands in manufacturing processes and quality assurance, particularly when workpieces with complex geometries are under inspection. This article deals with the verification of the previously presented three-dimensional calibration procedure for screw threads. Screw thread pitch diameters, the lead and flank angles are compared to those determined by the standardized method based on line-like, rather two-dimensional measurements and evaluation. In order to provide a reliable basis for the verification, one thread gauge was calibrated under laboratory conditions for precision metrology. Additionally, calibrations were conducted by three alternating operators on three different coordinate measuring machines to investigate the influence by user and machine. The resulting normalized errors of screw thread determinants under test and reference values are significantly smaller than 0.5 which indicates a high level of agreement.

由 Physikalisch-Technische Bundesanstalt 开发的整体螺纹校准新方法于 2019 年发布。 为了满足制造工艺和质量保证不断增长的需求，特别是在检查具有复杂几何形状的工件时，取得了重大成就。本文涉及对先前介绍的螺纹 3D 校准程序的验证。螺纹中径、导程角和牙侧角与通过基于线状而非二维测量和评估的标准化方法确定的值进行比较。为了给验证提供可靠的依据，在实验室条件下校准了一个螺纹量规，用于精密计量。此外，校准由三名交替操作员在三台不同的坐标测量机上进行，以调查用户和机器的影响。产生的归一化误差 受测螺纹决定因素和参考值的显着小于 0.5，表明高度一致。
