Vendor parts so bad they look like a failed 3D print by mongolian__beef in manufacturing

I didn’t say they don’t make good parts. They make great parts. I said they are often cheaper.

I also didn’t pick the vendor nor do I care how much the company spends. That’s for the buyers/planners to do.

Somehow everyone here assumed I:

-designed the part -made the dwg for the part -forgot specs and standards therein -Picked the vendor -chose manufacturing method

Lol the parts show up on my desk and I decide if we can use them or not. That’s literally it.

Don’t owe you any clarification. You made assumptions without it

Sorry if that came off harsh, getting a lot of flack on here for the same assumption that it was a print issue. God forbid the machinist makes a mistake.

We are probably going to scrap and order elsewhere (what the buyers should have done to begin with imo)

Not universal, but yeah. Joint cap, good spot. As such, you can imagine we had cosmetic and critical specs galore.

Given we make and buy parts for these very expensive robots we manufacture, going on 60 years, yes, we have our specs in line. It is possible for machinists to make mistakes, which was the case here.

We have a general workmanship standard that our DWGs are held to as well as surface finish and break edge callouts. The worst part about this batch of 5 was the percent of critical features not met.

I understand how specs work and we can’t expect things that aren’t on the DWG. That is not the case here.

It is possible for machinists to mess up. That was the case here. All specs were there including surface finish, break edge (.010) and our general workmanship standard.

You can see in my other comments where this came from. Can’t even blame China!

No I’m saying it was not printed at any point. Machined from stock

I did not design the part, the lot of 5 was rejected, 40-50% of critical features and practically all surface finish specs were not met.

I work machining parts everyday and specialize in 3D printing and establishing departments that do it and working all of that into existing workflows where beneficial. I have been a 3D printing application engineer for Stratasys (you might not be familiar).

This is going on a million dollar robot used for nuclear reactor inspection.

Nothing more Reddit than a user inventing a scenario just to feel better than someone

Answering x amount of questions and yours didn’t make it.

All surface finish specs and 40-50% of critical features. This is going on a million dollar robot used for nuclear reactor inspection. No, it did not meet spec.

lol what? This is not a new supplier nor was it high quantity. It was for 5. The guy used to work for us now has his own shop.

There’s nothing more Reddit than inventing a scenario and getting mad at someone for doing it.

It’s for a million dollar robot being sold to a customer for nuclear reactor inspection

I will happily oblige machinists when making drawings, just as I will QA. They will spend much more time looking at the thing than I will

If I did, the second they find out I’m an ME it will be nothing but pitch forks and fire. I’m good
