  2. Geometrical Product Specification and Verification - Wikipedia

    en.wikipedia.org/wiki/Geometrical_Product...

    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.

    ISO 25178: Geometrical Product Specifications (GPS) – Surface texture: areal is an International Organization for Standardization collection of international standards relating to the analysis of 3D areal surface texture.

    BS 8888 is the British standard developed by the BSI Group for technical product documentation, geometric product specification, geometric tolerance specification and engineering drawings. [ 1 ] History

  5. Dimensional metrology - Wikipedia

    en.wikipedia.org/wiki/Dimensional_metrology

    A print is a blueprint illustrating the defined geometry of a part and its features. Each feature can have a size, a distance from other features, and an allowed tolerance set for each element. The international language used to describe physical parts is called Geometric Dimensioning and Tolerancing (colloquially known as

  6. 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 ...

    Also confidence coefficient. A number indicating the probability that the confidence interval (range) captures the true population mean. For example, a confidence interval with a 95% confidence level has a 95% chance of capturing the population mean. Technically, this means that, if the experiment were repeated many times, 95% of the CIs computed at this level would contain the true population ...

    en.wikipedia.org/wiki/Geometric_algebra

    A ⁠ ⁠-graded vector space structure can be established on a geometric algebra by use of the exterior product that is naturally induced by the geometric product. Since the geometric product and the exterior product are equal on orthogonal vectors, this grading can be conveniently constructed by using an orthogonal basis ⁠ {, …,} ⁠.
