General CMM question



So I’ve been programming CMMs for about 5 years. I just started at an aerospace company as a CMM operator and programmer. Since I’ve been there I’ve used programs other people have written. My issue is I will run the program on some parts and the part will be good. Then I’ll get to another part in the lot and the program will check it and show bad, so I’ll check the part with another program that just loops the alignment a few times or use a different measuring method and the features will come in good. Is this a common thing or am I missing something? I’ve never had this issue before but I’m also not used to working with really tight tolerances.
