Comparación de módulos de análisis de tolerancias en ensamble mecánicos mediante los software CAD SolidWorks e Inventor.

Abstract

An experimental study is being conducted on the assignment of dimensional tolerances in mechanical assemblies with the aim of comparing the results obtained from the different CAT tolerance analysis modules TolAnalyst (SolidWorks) and Tolerance Analysis (Inventor). This comparison seeks to develop skills and evaluate the reliability of both tools so that users can interpret, apply, and analyze critical dimensions within an assembly. This knowledge expands and contributes to professional training, with higher standards and capabilities within the industry. The study consists of the selection and design of two mechanical assemblies, one static and one mobile, in the commercial software SolidWorks and Inventor, establishing the dimensional tolerance values for each part of the assembly based on its mechanical operation to define the independent and dependent values that are necessary for tolerance analysis. An experimental design method is established, in which the design of each part, dimensions, tolerances, assembly order, etc., is the same in each CAD program, and control dimensions are established to compile the results in each of the CAT modules. Finally, the results obtained in each module are analyzed using a data analysis tool, obtaining knowledge of important data, data trends, graphs, among others, by comparing the results of each TolAnalyst (SolidWorks) and Tolerance Analysis (Inventor) module with respect to the theoretical values to determine the reliability of the analysis for each previously selected assembly and thus determine the reliability of these CAT modules.
