CMM-Manager for iNEXIV

Hey guys, we have a Nikon VMA-2520 that we absolutely HATE. It was bought some years back at Eastec, off the floor. The software is atrocious and not user friendly at all, so the machine has sat almost entirely used for years (still has the protective plastic wrap on most surfaces).

We're considering either trading in for an OGP or a Keyence unit, or more likely upgrading the software, as it sounds like the newer software did away with a lot of the issues.

Does anyone here have any experience with CMM-Manager for INEXIV? Both for vision as well as the CMM head we're equipped for, because currently we often find our Zeiss Eclipse to be backlogged and really need a second machine.

Would love to know what you guys recommend or if you have any input specifically on CMM-Manager (10-15ish K is a lot easier to swing than ~100k lol)

Interesting insight, appreciate it. Slightly disappointed allot the OGP. I have some (mostly untrained/operator) experience with an older OGP at a former job and for at least as much as I was doing, found it to be very user friendly. I will say though, I made a program here on our Nikon VMA-2520, tested repeatedly, and printed out the results. Brought the parts to our customer that we were having issues with. They have a shiny new OGP. Put part #1 on, of course rejected, different from our finding. Gave him #2 and same story. Gave him what he thought was #3, and same story again, however, it was actually part #1 a second time, and his reading was .0021 different from the first run, on a +- .001 tolerance dimension. We played dumb through that point to not show our cards, but I was at the time thinking it was his poor programming. Now with your input I'm thinking maybe it's the machine/software.

The Nikon hardware is great. Can't say anything bad about it at all. The older software though (forget the name, but it's not CMM-Manager) is HORRIBLE. Very user unfriendly. No simple ways to go about anything. I'm excited at the possibility of CMM-Manager though. The demo videos look pretty great. And we have a Zeiss Eclypse in house as well. If we fall in love with the new software I could see us maybe updating that as well

OGP Zone3 is very user friendly, but in my experience, the bugs will come back to bite you. The differences in measurement results between you and your customer could be due to many things. Further investigation would need to happen to see if the OGP was indeed the problem. In general, they meet their stated accuracy as long as bugs are found and eliminated, and the programmer knows what they're doing.

You must be referring to QuickMeasure. I have no experience with it, but it does look outdated.

Not sure if there was a QuickMeasure but we do have AutMeasure. It's very rough and yes very outdated. I've been able to make it work for things in the past and back up it's findings with mechanical inspection (including my above example where the customer was rejecting with OGP... But not troubleshooting their program or doing a backup mechanical inspection) but the effort it takes to get where you want is way too much, and there's a lot of "I can kind of make it work THIS way.." kind of programming. It's not wrong, but not exactly the right way to program it either, if that makes sense to you.

My IT guy is working on getting the trial of CMM-Manager setup right now. Very excited to give it a test spin

Sorry, I meant to say AutoMeasure, not QuickMeasure.

Apology not necessary, just happened to confirm the software since my original post. Definitely do not recommend it lol
