Abstract
The geometric dimensioning and tolerancing system is an old tool that only nowadays has gained space in the Brazilian metrology scenario. With comprehensive tolerance zone concepts and symbology that facilitates the understanding of technical drawings, it is widely used in the automotive industry, and has significant importance in the aeronautical industry. Its importance has been recognized in both industry and academia, due to the development and improvement of computational tools, making GD&T a viable alternative to the Cartesian system. This article aims to present a comparison between the GD&T and, the traditionally used, Cartesian method highlighting key concepts for the understanding of the geometric method and its importance. A bibliographic survey on GD&T applied to coordinate measuring machines initiated the development of this study, followed by an application of the GD&T techniques in a coordinate measuring machine with the help of its computational system, the MCOSMOS. The experimental results demonstrated the importance and efficiency of GD&T in control and in dimensional and geometric analysis of manufactured parts.
