Hi. I am performing MSA on nylon parts using Aberlink 3D. I take out part from fixture and then put it back x 25. All my dimensions have no more than 5 micron variation except one - cone angle on one part and on different part it is angle between planes. Difference in angle is massive. If all other dimensions have small variation i assuming that fixture is good. What is the best method for measuring cone to get the smallest variation in cone angle ?
