Résumé
Jigless assembly is a flexible and cost-efficient alternative to traditional jig-based methods in mid and large-scale manufacturing. Accurate metrology systems, such as Indoor GPS (iGPS) offers us a technological opportunity to achieve this type of assembly while guaranteeing flexibility and precision. This study proposes a methodology for empirical estimation for measurement uncertainties at one single point within a predefine work volume, inherent in the use of iGPS, following GUM guidelines. The methodology involves identifying primary uncertainty sources, including equipment errors, repeatability, and references used for the calibration. Experiments were conducted using an artefact bar calibrated by an Absolute Laser Tracker AT960, with statistical analysis performed to quantify the impact of calibration, warm-up time, and measurement distance. The findings contribute to understanding iGPS capabilities and offer practical insights for optimizing measurement strategies in jigless assembly, enhancing precision and efficiency in large-scale manufacturing environments.
