【文章內容簡介】 aution, though, as slotted holes do not adequately retain large wiring bundles Detailing and Dimensioning Training ? Dimensioning: ? Dimensioning wire assemblies is acplished with two different tolerance systems。 clip tolerance and cut length or takeout tolerance. ? Nominal dimensions for wire assemblies are selected by determining the minimal dimension from layout drawings and design aid bucks, then adding in the minus cutlength tolerance. Therefore a wire harness built to nominal length would seem long Detailing and Dimensioning Training ? Dimensioning Cont. : ? There is an interdependent relationship between the clip tolerance and the cutlength tolerance which must be examined during the design. The application of the clip tolerance and the takeout tolerance on the wire assembly drawing determines how well the wire harness fits by specifying where the cut length is positioned in the vehicle. Dimensioning multiple retainers from a mon fixed point aids in manufacture of the wire harness but spreads the cut length tolerance between the retainers. The design engineer needs to examine the effect this has on wire harness fit versus a retainer to retainer dimensioning scheme Detailing and Dimensioning Training ?
