Designing parts to be manufactured in different countries

David Israel

Have you run across this situation? A company has production facilities in the US and other countries. They want to make drawings that can be fabricated in all of their locations. The problem with sheet metal parts is that the sheet thicknesses that are locally available differ between the US and the rest of the world (gage thickness vs. mm thickness).

 

Have you seen other companies support multiple build locations and variations in available material like this? If so, how much success have they had trying to support both sets of material? How do they setup their sheet metal models to accommodate this?

 

I can see a couple of different methods to achieve this. First, you could have two configurations for each part. But, multiple configurations makes the parts more complex and there could be some other complications in using this method. You could also create two completely separate sets of parts and assemblies: one imperial and one metric. This keeps the parts simpler, but it makes it difficult to maintain equivalence between two corresponding parts.

    No matter what they do, if they issue one drawing with one thickness, parts manufactured in another location won't be to spec.

    If the only thing that is changing is the thickness - could they populate the gauge table used to build the parts with information that will report into the title block. eg have it say 20 gauge/1.2mm in the material description. The true dimension of the thickness will be wrong, but if you make parts in different locations, you're going to get different thicknesses.
