Hello, I'm fairly new to CMM programming with CAD models, I just started a month ago and I haven't had any major problems until now. I have to say that I never had a proper formation on CMM programming at all, I learned everything I know by my own.
My problem is that I have to measure a part which it's datums are given in car body coordinates (2 circles and a slot) and I've never aligned a part like this before. I tried doing a 3-2-1 iterative alignment and then a best fit as I always did, but I can't get it to work because the deviations of the real part from the CAD are so big that whenever I try to measure a hole the probe bumps into the part like 3 or 4 mm away from the hole and as much as I try to do a better best fit alignment it doesn't seem to work. so after plenty of time of trial and error I gave up and asked for help to my co-workers, but they use different CMM machines and software (Metrolog XG), so they don't know how to use PC-DMIS. They suggested me to perform a RPS alignment to try to get around this problem, but I have no clue on how to do it in PC-DMIS. Anyone who knows how can I get this to work?
Any help I could get would be highly appreciated.
Please, be aware that i'm a newbie in CMM programming, so try to be as clear as you can.
