Abstract
The dimensional variations inherent in a manufacturing process are the reason for the existence of the acceptance tolerance concept on a product characteristic. The geometric quotation system has many advantages over the Cartesian system by avoiding ambiguity in the interpretation on form, orientation and location errors. In the automotive sector the two main standards that define the geometric quotation on a mechanical design are ISO1101/2012 and ASME Y14.5-2009. However, there are differences of interpretation even when the same symbols are mentioned in these standards. When a company supplies parts to OEMs that apply different geometric control standards, it is important to know these differences to ensure product quality. This article presents the results of perpendicularity control using each standard and their difference as an example of the impact when choosing one of them. Data from a still ongoing survey show how these differences between the standards are still little known among professionals, mainly within the automotive industry in Brazil.
