A NEW METHOD FOR MEASURING INTERNAL DIAMETERS.

Analyzing the current performance of the bore measurement tools used in the manufacturing process or in final control laboratories, it was found that optimizations can be made to increase the precision of measurements taken with these instruments. In order to achieve this goal, research has been conducted to improve the reliability and increase the operational lifespan of the measurement instruments, addressing the deficiencies resulting from premature wear of their components. Experimental results show that a 1:1 transmission of the actual error value taken by the probes to the dial for reading the execution deviation has been successfully achieved. Through a competitive design that reduces the number of component parts, this has led to the removal of the amplification mechanism consisting of levers and gear wheels from the construction of the current instruments, which were sources of errors originating from manufacturing and premature wear. As a result of the experiments conducted, these characteristics have emerged in the instrument's construction, which is a realization of the congruence of triangles method. [ABSTRACT FROM AUTHOR]
