Profile Specification in the Assembly of Machine Designing Based on Geometric Dimensioning and Tolerancing (GD&T) by FEA Method

The setting of allowable tolerances for the profile of a structure is generally determined by the functionality of the components desired by the designer after assembly. The specified values fall within the scope of the ASME 14.5-2018 standard, which outlines the limits for values that designers can choose but does not specify suitable coordinate tolerances for the components. This research introduces a design process for machinery components that focuses on controlling deviations and geometric dimensions using Geometric Dimensioning and Tolerancing (GD&T), following the ASME 14.5-2018 standard. Explores the potential impacts of profile deviations on components by analyzing the effects through Finite Element Analysis (FEA). The analysis aims to examine the intensity of forces during assembly using FEA and assess the resulting damage between components. This article delves into the core content of the research, emphasizing the design of machinery components using GD&T based on the profile standard and presenting the FEA results. The study highlights the importance of utilizing GD&T in design and FEA for controlling and improving the accuracy of components produced based on profile specifications. The results of this research underscore the significance of incorporating GD&T in design and employing FEA to achieve precision and high efficiency in the assembly process.
