Linear Tolerances Limits & Fits - Institute of Technology ...

IT,Sligo computer aided design Tolerances Linear Tolerances Limits & Fits Manufacturing is principally concerned with ensuring the functionality, interchangeability and quality of the parts and products that have been designed. Designers must recognise that manufactured parts will vary somewhat from the original design and that it is not possible to repeatedly machine components to exact nominal dimension. Therefore design acceptable Tolerances must be determine which indicate how much the part can safely vary while still maintaining acceptable function, and these Tolerances must be communicated on the drawings. When dimensioning a part drawing, Linear Tolerances are used on the functional features of the part to specify the Tolerances that are allowable.

IT,Sligo Computer Aided Design Tolerances 2 Standard Fits: As designers recognise that manufacturing must be told how much a part may deviate from the nominal size while still functioning as intended, and due to the necessity for interchangeabilty, a system of Limits and Fits has been developed. While the system is
