I used to work in incoming inspection at an aerospace manufacturing company. And now work in technical sales (industrial automation).
If you want the tolerances changed my advice would be to go to the purchaser at your company and suggest that they seek quotes from a different supplier at whatever you think the actual tolerance should be.
Purchasers are often incentivized for cost reductions.
Obviously this only works from a parts receiving context though.
Do you think we have not thought of asking the engineers to loosen the tolerances?
At my job, there’s a lot of times where manufacturing has changed things without breathing a word to engineering
I’m not the person you were replying to.
