We use our arm for measuring parts after test. Right now trying to see if we can compare a scan of a sample taken before test to a scan of the same sample taken after test. Our romer arm and sample fixture don't move so I don't think I need to worry about doing any sort of alignment... yet. Does anybody know if there is a way to do a colormap between two scans instead of between a CAD and a scan?
I tried exporting one of the scans to an IGES and then importing the same IGES to try the scan but nothing showed up.
You'd need to mesh the master part and export it as STL, and then import that into your program with the scan of the second part and compare it using the Point or Surface colormap.
Hi @NAhmed,
The instructions other members gave you are correct. I have a few slides which show the steps in case they may be helpful to you. Please let me know if you need any assistance.
Thank you guys very much!! I got it figured out now!
On a sideote, is there a way to export the colormap as results than can be viewed in another program? (Thinking maybe HyperView). I know how to make reports, but it would be a lot easier if I could just pass this off to my engineer
It seems that you don't indicate that the arm changed and you recall A1 (alignment of the first cop).
You should have an option to say that the arm moved, and I believe you shouldn't recall A1 (I'd never used arm... !)
It's the same as for moving the part on the CMM. I'm not sure how well it works. I think it's just referred to as "leapfrog" but is the same as the instructions for moving/flipping a part on the CMM. The same thing is happening in both cases.
That doesn't help after the 2 COPs are already scanned in the same program, I think it's too late for that?
actually, it is not quite the same as the EQUATE alignment that you do on the CMM, it basically does the same thing, and it is actually called LEAPFROG.
Yeah, it's a 'start-over now that you know' kind of thing. The learning curve as it were.
