  2. ASME Y14.5 - Wikipedia

    en.wikipedia.org/wiki/ASME_Y14.5

    ASME Y14.5 is a complete definition of geometric dimensioning and tolerancing. It contains 15 sections which cover symbols and datums as well as tolerances of form, orientation, position, profile and runout. [3] It is complemented by ASME Y14.5.1 - Mathematical Definition of Dimensioning and Tolerancing Principles.

    Example of true position geometric control defined by basic dimensions and datum features. Geometric dimensioning and tolerancing (GD&T) is a system for defining and communicating engineering tolerances via a symbolic language on engineering drawings and computer-generated 3D models that describes a physical object's nominal geometry and the permissible variation thereof.

  5. Dovetail rail - Wikipedia

    en.wikipedia.org/wiki/Dovetail_rail

    Dovetail mount can also refer to a dovetail track running perpendicular to the bore, [9] often used for smaller front sights posts and rear sights blades found on handguns and some rifles. This mounting method is meant as a semi-permanent friction fit mounting solution where a slot is milled , for instance in the slide of a pistol, [ 10 ] and a ...

    Geometrical Product Specification and Verification (GPS&V) [1] is a set of ISO standards developed by ISO Technical Committee 213. [2] The aim of those standards is to develop a common language to specify macro geometry (size, form, orientation, location) and micro-geometry (surface texture) of products or parts of products so that the language can be used consistently worldwide.

  7. Engineering drawing - Wikipedia

    en.wikipedia.org/wiki/Engineering_drawing

    Coordinate dimensioning was the sole best option until the post-World War II era saw the development of geometric dimensioning and tolerancing (GD&T), which departs from the limitations of coordinate dimensioning (e.g., rectangular-only tolerance zones, tolerance stacking) to allow the most logical tolerancing of both geometry and dimensions ...

  8. ASME Y14.41 - Wikipedia

    en.wikipedia.org/wiki/ASME_Y14.41

    ASME Y14.41 is a standard published by American Society of Mechanical Engineers (ASME) which establishes requirements and reference documents applicable to the preparation and revision of digital product definition data (also known as model-based definition), which pertains to CAD software and those who use CAD software to create the product definition within the 3D model.
