Abstract:
In the present-day industry of designing and manufacturing machinery components, particularly those crucially impacting assembly conditions such as automobiles, aircraft, and mechanical machinery, adherence to Geometric Dimensioning and Tolerancing (GD&T) standards is imperative. These standards, delineated in engineering drawings, are meticulously crafted by designers to precisely meet desired component characteristics while aligning with functional requirements. Widely utilized in ensuring manufacturing quality, GD&T specifies geometric shapes and coordinate dimensions. Researchers are keen on investigating assembly behavior, particularly focusing on deviations from GD&T parameters, notably angularity and position, as per the ASME 14.5-2018 standard. Utilizing finite element analysis, post-assembly behavior is scrutinized concerning deviations from the specified GD&T values in engineering drawings. Analysis outcomes manifest in stress values, offering insights into the severity of assembly behavior, which, in turn, can significantly impact operational performance
