Aplicações de Técnicas de GD&T em Máquinas de Medição por Coordenadas

Abstract

With the evolution of manufacturing processes and serial production, there arose a demand to improve measurement methods. Moreover, metrology developed in the context of Industry 4.0 has driven the need for automation to keep companies competitive with world market leaders. Additionally, GD&T (Geometric Dimensioning and Tolerancing) stands out as an essential requirement for standardizing the design and functional association of the projected components, providing engineers and designers with the necessary tools to communicate their real intent and define tolerances and the geometric relationships of parts unambiguous (TORNINCASA, 2024). During this process, the use of a Coordinate Measuring Machine (CMM) emerges as a powerful tool, enabling increased measurement accuracy. This work presents the basic principles of GD&T techniques and evaluates the effectiveness of their application in the dimensional control of a machined part using a CMM.
