Guesswork is never recommended in engineered products. When we talk about the manufacturing process, we need uniformity in drawing specifications and even in interpretation. So, let’s now explore some of the basics of the GD&T standard. No matter what year standard your company is using, the basics are all the same. The standard, and associated gd&t symbols are fully utilized by companies involved in designing, manufacturing and developing industrial products and parts. So, the latest standard for GD&T is that of ASME Y14.5-2018. The first standard which incorporated completely the GD&T guidelines was ASA Y14.5-1957 (which was adapted/updated from concepts put forth in MIL-STD-8) followed by USASI Y14.5-1966, ANSI Y14.5-1973, ANSI Y14.5M-1982, ASME Y14.5M-1994, ASME Y14.5-2009. The ASME (American Society of Mechanical Engineers) has established this standard for dimensioning and tolerancing. In this article, we’re going to look at the background and some basics of gd&t symbols and definitions that are important for a engineers and designers to understand: Background of ASME Y14.5 & GD&T It is an international standard that is used throughout the globe.
It helps further in manufacturing and inspection processes of mechanical parts. The standard establishes symbols, definitions, and rules that are used for defining dimensions and tolerances. The purpose of this standard is to establish requirements of industry and provide a way to communicate drawing objective as per project specifications. GD&T aims to communicate the design intent in a way that the desired form, fit, function, and interchangeability of feature is conveyed on the drawings without confusion.
