The precise determination of the position of internal threaded holes is a key aspect of engineering manufacturing, particularly in applications with high accuracy requirements. This study focuses on evaluating the position of threaded holes using coordinate measuring machines (CMM) and product geometric specification (GPS) methodologies. It analyzes indirect measurement strategies, utilizing both contact methods (CMM) and non-contact optical scanning. Experimental evaluations compare these methods in terms of accuracy, repeatability, and time efficiency. The results provide a critical analysis of the advantages and limitations of each approach, forming a foundation for selecting the optimal metrological methods within manufacturing processes. Additionally, the study offers recommendations for optimizing measurement strategies, considering technological constraints and practical applications.

摘要

The precise determination of the position of internal threaded holes is a key aspect of engineering manufacturing, particularly in applications with high accuracy requirements. This study focuses on evaluating the position of threaded holes using coordinate measuring machines (CMM) and product geometric specification (GPS) methodologies. It analyzes indirect measurement strategies, utilizing both contact methods (CMM) and non-contact optical scanning. Experimental evaluations compare these methods in terms of accuracy, repeatability, and time efficiency. The results provide a critical analysis of the advantages and limitations of each approach, forming a foundation for selecting the optimal metrological methods within manufacturing processes. Additionally, the study offers recommendations for optimizing measurement strategies, considering technological constraints and practical applications.
