I like our Optiv 321GLtp, but one thing I have not been able to figure out is softening machine lines. The machine has a hard time deciphering between machine lines, the correct shadow, and the material to the left of the machined surface. This is at 1x zoom. We have another vision system that is zoomed out further, which in turn, "softens" the machine lines in order to pick up the edge correctly. We are going to try to implement that one to do these checks, but have not because there is a flatness callout on the machined surface. So the O ptiv is a one-stop-shop. I have tried top light, shutting off rings lights, filtering, RGB mixing, etc to automate the edge pickup. None of this works so it is a manual measurement.
Is there a way to soften those machine lines for the vision to grab the thin black shadow that is near the crosshairs?
Hi all you Vision guys. Holy cow. My guess is that it all depends on your machine. For me? If I setup for Barry's edge check - for sure it would not check well on his, but on my 443 performance... presto!
Like said, there are SO many tweaks for checking in Vision.
Example: check I.D. on a ring gage. Depending on illumination, focus, zoom, edge etc.... you can get (I have anyway) crazy results from +- .001 if not more. So, somehow there needs a way to 'Master' settings to a 'Master' ring (or surface, or ??) The measurement will change depending until setting parameters for similar parts/features. This is regardless of using the glass/lasered plate Hex supplies.
Maybe I'm wrong, but as you mention... Neil might need to come in on this thread and fill some info in! I have gone crazy with settings in illumination - especially when I create one call it sea... go to next similar feature and using the illumination I set, and I get '
sea*'. The asterisk means It doesn't use it!!! I am totally lost on that.
My last take is that I agree Barry, the Specified Edge is a very foggy notion. With as many times experimenting? The Matching Edge has always been the best accuracy - when the feature can be verified with other method. For profiles? Ha.... many products in my last company were +-.001 and they just stuck with a comparator & a mylar. Inspector eyes did not want to piss off the production manager with reports from the Optiv (but actually? they were accurate)
