Machining Standards - cleanup cut on base material
Machining Standards - cleanup cut on base material
(OP)
For sake of argument I am buying a piece of 6" aluminum plate against AMS-QQ-A-250/11 - in reality what is the real usable thickness of material that can be 'used' in a design? - or worded in another way - forgetting about flatness etc.. how much cleanup it normally taken per side to accounting for the material manufacturing process? Is this a % of the thickness that could be applied to all plate products.
So think of it this way, as a designer I am selecting material sizes as part of the design process. Say I need a finished value of 1/2" - I certainly wouldn't buy a piece of 1/2" plate - because I would never meet tolerance because the plate needs to be cleaned up - but maybe I could change the design to have a finished value of .450" and meet tolerance because I know that I need say .010 per side cleanup. Now if I really needed .50 I could start with a piece of 3/4" but think of the additional machining required (but then it could be a cost trade off etc etc...)
Is there a spec somewhere?
Thanks for listening..

I have used all these companies and the product was as good as or better than advertised.
