Here the different language people are designer, manufacturer, quality inspector and the language is GDT. The quality of the product is attained by these three contributors with the perfect agreement. It uses a symbolic language on engineering drawings and computer-generated three-dimensional solid models that explicitly describe nominal geometry and its allowable variation. It tells the manufacturing staff and machines what degree of accuracy and precision is needed on each controlled feature of the part. GDT is used to define the nominal (theoretically perfect) geometry of parts and assemblies, to define the allowable variation in form and possible size of individual features, and to define the allowable variation between features. Two examples are linear dimensions and feature control frames using a datum reference (both shown above). One such standard is American Society of Mechanical Engineers (ASME) Y14.5. This article is based on that standard, but other standards, such as those from the International Organization for Standardization (ISO), may vary slightly. The Y14.5 standard has the advantage of providing a fairly complete set of standards for GDT in one document. The ISO standards, in comparison, typically only address a single topic at a time. There are separate standards that provide the details for each of the major symbols and topics below (e.g. While little is known about Parkers life, it is known that he worked at the Royal Torpedo Factory in Alexandria, West Dunbartonshire, Scotland. His work increased production of naval weapons by new contractors. The datum reference frame can describe how the part fits or functions. GDT can more accurately define the dimensional requirements for a part, allowing over 50 more tolerance zone than coordinate (or linear) dimensioning in some cases. Proper application of GDT will ensure that the part defined on the drawing has the desired form, fit (within limits) and function with the largest possible tolerances. GDT can add quality and reduce cost at the same time through producibility. Every feature on every manufactured part is subject to variation, therefore, the limits of allowable variation must be specified. Plus and minus tolerances may be applied directly to dimensions or applied from a general tolerance block or general note. For basic dimensions, geometric tolerances are indirectly applied in a related Feature Control Frame. The only exceptions are for dimensions marked as minimum, maximum, stock or reference. Every dimension and tolerance required to define the finished part shall be shown on the drawing. If additional dimensions would be helpful, but are not required, they may be marked as reference. Additionally, dimensions should not be subject to more than one interpretation. The geometry should be described without explicitly defining the method of manufacture.
