Oh lords I feel this. Machining plastics and people expect one thou tolerances.
Why not ask the engineers to loosen the tolerances? Changing things behi d their back will only lead to issues down the line
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.
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.
Engineers usually have a "not my problem lol" kind of mindset, in my experience
That's exactly what inspired me to this meme... I get given prototype lineal profiles up to 12 feet long and they expect hardware locating hole tolerances of .005 on an extruded part that's warped and wavy probably .030-.060 along it's entire length.... not happening bud, split the difference and ship it.
Price accordingly and it might stop.
"Oh you want a four-meter lathe? Ch-ching, sign here. Gonna build another warehouse on this job."
Unfortunately its all company internal work, can't use the stupid tax to make stupid projects go away because that just results in angry yelling meetings.
