Prevention and Early Detection of Problems Related to the Decalibration of Assembly Tools and the Loosening of Threaded Connections

Abstract

Aim: The objective of this article was to identify and assess modern methods and tools used for monitoring the calibration status of wrenches used in assembly processes, as well as for the early detection of the degradation of bolted joints. The study sought to develop recommendations for implementing effective control procedures and technological solutions to minimise the risk of errors and enhance the quality and safety of production processes.

Methodology: The primary research methods were mathematical data analysis and participant observation.

Results: In the analysed company, wrenches are calibrated once a year in accordance with normative requirements. However, maintaining quality parameters would require the more frequent calibration of the wrenches, which would result in production line downtime. The authors proposed solutions that could extend the interval between calibrations.

Implications and recommendations: The application of various technical solutions can help maintain the required technical parameters of threaded connections without the need to halt the production line for proper wrench calibration (extending the calibration intervals).

Originality/value: The article addresses the important issue of balancing the frequency of wrench calibration with its cost and the continuity of the production process.
