ASME Y14.5 is a standard published by the American Society of Mechanical Engineers (ASME) to establish rules, symbols, definitions, requirements, defaults, and recommended practices for stating and interpreting Geometric Dimensions and Tolerances (GD&T). [1]
In locksmithing, the allowable tolerance [3] is decided by the range of minute differences between a key's size and shape in comparison to the size and shape required to turn the tumblers within the lock. Key relevance is the measure of similarity between the key and the optimal size needed to fit the lock, or it is the similarity between a ...
Many corporations have such standards, which define some terms and symbols specific to them; on the national and international level, ASME standard Y14.38 [1] is one of the standards. Australia utilises the Technical Drawing standards AS1100.101 (General Principals), AS1100-201 (Mechanical Engineering Drawing) and AS1100-301 (Structural ...
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.
A hex key (also, hex wrench, Allen key and Allen wrench, Unbrako or Inbus) is a simple driver for bolts or screws that have heads with internal hexagonal recesses ().. Hex keys are formed from a single piece of hard hexagonal steel rod, having blunt ends that fit snugly into similarly shaped screw sockets.
Computer numerical control (CNC) wire-cut EDM machines allow for a wide variety selection of keyways to be cut, inclusive of multiple keyways on the same hub. The main limitations of CNC wire-cut EDM is the time it takes to cut a keyway as well as the size of parts a given wire-cut EDM machine can accommodate. [9]

ANSI was most likely formed in 1918, when five engineering societies and three government agencies founded the American Engineering Standards Committee (AESC). [8] In 1928, the AESC became the American Standards Association (ASA). In 1966, the ASA was reorganized and became United States of America Standards Institute (USASI). The present name ...
