Dimensions, Tolerances and Assemblies - Coggle Diagram

- - - - Important of tolerances
        
        tolerance is not given, exact measurements of the parts have to be made. or else rejection rate would be high
        
        Tolerances ensures good quality control for parts from different companies
        
        The range of tolerance will be done by manufacturing method. since different manufacturing has different method in degree of tolerances
        
        Tolerances will ensure that mating parts of an assembly interface and fitted nicely
- - - - Chain Dimensioning
        
        Combined dimensioning
        
        Use both chain and parallel
        
        Dimensioning small features
        
        Placing arrow heads between the extension lines make the dimension very difficult
        
        Dimensioning of multiple features
        
        to dimension multiple same dimensions
        
        Dimensioning of radius
        
        Dimensioning of circle, arc and hole

        shows a radius dimensioned with the Centre of the radius located on the drawing
        
        should only be used if the function of the object would not be affected by the accumulation of the tolerances
      - simplifies parallel dimensions
    - - consists of several dimensions originating from a common reference
  - - - drawn as thin lines that extend from the object
        
        being dimensioned and terminate with arrows or other symbols
  - - - extension lines are used to indicate the boundaries of a dimension
      - drawn as thin lines with arrows at the ends.
  - - - to indicate the size and location of features or objects
        
        provide specific measurements and are typically accompanied by numerical values or symbols to convey precise dimensions.
        
        drawn as thin lines with arrows or tick marks at each end, indicating the extent of the dimension.
  - - - can deviate from its intended design or target dimension
        
        tolerance is an essential concept that helps ensure the interchangeability, functionality, and quality of manufactured parts
        
        Tolerance is typically specified using a combination of numerical values and symbols
  - - - provides specific information about the dimensions of various elements in the drawing
        
        helping to convey precise measurements to those interpreting the drawing.
        
        dimensions text plays a crucial role in technical drawings by providing precise measurement information
      - dimension lines, indicating the size or measurement of a feature or object.
