Horizontal CMM Experience? Looking for info...

Sorry, I didn't think it was really a PC-DMIS related question.... more of a life in general question.

Someone can move it if they see fit.

It is ABSOLUTELY INCOMPREHENSIBLE to reject someones work with an un-calibrated instrument. Especially a CMM. ESPECIALLY a horizontal CMM. There is so much wrong with their line of thinking its not even funny.
Sounds like your on the right track. I'd still perform a CPK on your ball bar internally, then send it out for measurement like you said to the outside sounce. Your CPK study, along with their acceptance of your ball bar, along with your cert SHOULD be enough. All you can do is plead your case with what you've got.

If they still refuse to accept your data, then I'd broach the topic of having the fixture returned & doing a CPK on that as I have said previously.

Somethings got to give...and if you can prove from 8 different angles that you're right and all they've got is an uncalibrated machine that has known hardware faults and a "guy that they trust"....then not only will you gain some respect at your company but they won't challenge you again either.

I deal with this a lot. ESPECIALLY with aerospace and medical OEMs who couldn't program/design/manufacture their way out of a paperbag

DAN_M My knowledge of CMM outside my little bubble is so limited. I'd love to learn more about Aerospace work one day. I kinda thought that was the highest skill point in this field, was I wrong?

I'll do a full study on the ball bar and see what happens. I just don't get why they're being so stubborn. Everyone else I've dealt with running CMMs has been so cool and helpful, like we're on the same team...

I think a big part of it is we're a relatively young company and I'm a young programmer/Figure-***-out-guy and they're trying to jostle for pricing or something? They're a big company though so I would hope they'd be more credible than that.

Of course when the customer questions our results the owners start questioning me and I just end up confused because I know our numbers are good.

Thanks for making me feel better

Aerospace and medical are what I deal with every day. They are considered to be "top tier" work...but once you get down to it..its all the same stuff with tighter tolerances and slightly different customer requirements.

Absolutely do a study on that bar. This is critical to proving your case. And will make you look like a G to your boss.

Rest assured my friend...the larger and more "reputable" the company is, the more they will TRY to beat you into a corner and make you admit you're wrong even when you know that you are 100% correct. This is done to protect their rep, yes beat you down in pricing (they're a huge company, thats how some of them get that way), and to avoid a corrective action on their end. If they can convince you that they're right even when they're wrong, they save time effort energy and paperwork. Be professional, but DO NOT let this happen.

I know what you mean...I am 26. Self taught until I got my first legit training 2 years ago. I learned how to program by literally sneaking in my first shop at night when I wasnt supposed to be there and using the CMM/watching youtube videos/studying pre-existing programs until 2am some nights. When you prove your case (I have supreme confidence that you will) your boss will have gained some respect for you and hopefully your customer will give you more work.

DAN_M So we're basically the same person then haha. I'm self taught, I'd love to have some training though... maybe one day.

I'm the first to admit when I'm wrong, but all the numbers are in my corner right now... So We'll see how the ball bar goes and I'll let ya know what ends up happening

Thanks for helping on my quest for G-dome!

It took an act of nature for me to get some formal training. A thunderstorm took out our twenty year old machine, which forced the company to buckle down and finally buy a new one. The new one came with two seats of level one training. If it weren't for that, I would still be fumbling around with DMIS 4.3 on a Windows XP computer with no internet or network connectivity.

I like to think your machine was in a field or something and randomly got hit by lightning.

No worries brother, keep fighting the good fight

CMM field work? That would be interesting.

Taking "out standing in our field" too literally.
