This paper presents a comprehensive exploration of an experimental device designed for determining friction coefficients between a circular bar and a set of wheels in a feed mechanism. In the realm of mechanical engineering, where efficiency is paramount, understanding and quantifying these coefficients play a crucial role in designing and optimizing mechanical systems. The research objectives encompass the development and testing of the experimental device, rigorous analysis of the results, and an assessment of its practicality and accuracy in discerning friction coefficients within advancing mechanisms. Originating from the practical necessity of designing a mechanism for advancing composite rods in manufacturing lines, this research delves into the importance of characterizing friction coefficients in bar element mechanisms. The methodology involves the implementation and testing of the experimental device under controlled conditions, data collection, and the application of analytical techniques to evaluate friction coefficients. The obtained results provide a nuanced understanding of friction coefficients in bar feed mechanisms, with implications for the design and optimization of mechanical systems. The conclusions emphasize the need for careful analysis of frictional forces to enhance the performance and durability of these mechanisms. [ABSTRACT FROM AUTHOR]
