critical dimensions - Mechanical engineering general discussion
2002年9月10日 · If you are familiar with GD&T, you can use Basic dims and feature control symbology to identify critical dims. Also, some CAD packages have built-in options that are used during 2D drawing creation to identify dimensions that needs to be inspected to.
Engineering Drawings & GD&T For the Quality Engineer - CQE …
Dimensions should be arranged for optimum readability; An angular dimension of 90° is implied for any 2D view where no angle is specified & lines are shown at right angles; Dimensions [and tolerance] apply only at the drawing level where they are specified
What are the Significant (SC) and Critical characteristics(CC) in ...
2024年7月31日 · A Critical Characteristic (CC) is the dimension/feature of a material process, part, or assemblies. The CC Characteristics is mainly given for regulatory requirement (safety, regulation/Legal, or environmental) purpose.

A convenient guide for Geometric Dimensioning and Tolerancing (GD&T) symbols at your fingertips. Click on the links below to learn more about each GD&T symbol or concept.
General dimensioning symbols are shown first. Some of these symbols are also used in tolerance specifications. The second set of symbols are used for toler-ances. 1.3 Symbol sizes are shown in the figures as values propor-tional to the letter ‘h’. The letter ‘h’ represents the predominant character height on a drawing.
Critical Dimension - Drafting Standards, GD&T & Tolerance …
2012年5月15日 · Critical dimensions are subjective, based upon the function of the particular component being inspected. You would have to know the function and fit requirements for the part in question to determine critical print dimensions.
Correct placement of critical dimension symbol (inspection symbol …
2012年8月16日 · I have a question regarding the correct placement of critical dimension symbols (aka inspection symbols) relative to the dimension it is associated with: Is it incorrect to place this symbol between the dimension value and the dimension line that points to the feature? or does the dimension value always have to be adjacent to its dimension line.
The ASME Y14.5 GD&T Standard | GD&T Basics - gdandtbasics.com
2020年7月24日 · The ASME Y14.5 standard establishes symbols, definitions, and rules for geometric dimensioning and tolerancing. The purpose of the standard is to ensure clear communication of detailed information throughout the design and manufacturing process for mechanical parts.
Critical Dimension - Drafting & GD&T - SimpliEngineering
2020年5月11日 · On my drawings, all the dimensions are critical. If the drawing is sloppily prepared, we can assume that many of the tolerances are complete nonsense. The critical dimensions are the ones where the tolerances are not complete nonsense. There is the manufacturing issue that some tolerances are difficult to achieve.
