INSPECTION DIMENSION Standard
INSPECTION DIMENSION Standard
(OP)
Hello All
Does anybody know of a standard that describes the method to indicate which dimensions you want inpected on a drawing. SolidWorks and PRo/E use a rounded ended box around the dimension to indicate this, but I have been unable to find any standards for this pracice.
Cheers
Rob

When I worked in the automotive field, we put a synbol on certain dimensions that we marked as Key Product Characteristic and had a note that explained what the mark ment.

All dimensions are inspected, but we created a special symbol for special features that need to be validated for use. When we use the symbol, we create a general note explaining the symbol.

I know some companies that use the CAD "inspection dims" bubble as a marker for critical dims. During first artical inspections, all dims get measured, but after that, only the critical dims are inspected for tracking. It's suppose to be a time saver, but I see problems with that, unless the parts are always made on dedicated machines.

For MOST small to medium mfg'ers a number circled or star with a note is used. A majority out there ARE small to medium with a assembly consisting of only a few parts swaged, welded, pressed, or bolted together. They have no need of expansive cad systems or more then one assembly dash detail sheet. Ever try to check a shoulder diameter of a conveyor roller after assembly and sent out for first article packaging? You can not.
The important things to stay away from are the rectangular box (BASIC) dimension and things that may be taken other ways, if ISO have designated one yet please info me but as of yet I have not heard. A on-sheet tab with your customers or your spc/quality (which usual is taken from your customer or sales)dimension will thell quality what is needed for ppad-first article.
