I'm sure the question has been asked but here goes. When I'm measuring a point I am turning the probe comp off. For some reason my upper management (who do not run the equipment) are telling me to NOT shoot them as an uncomp point. Other than me telling them that a comp point is giving me a false reading how do I explain o them this is the proper way?
You have a couple of options that I would try. The first would be to do the original alignment that you stated above, and continue to measure the holes as "comp off" points. The second would be to try the single point circle and see if your measurements repeat the first set of data. The third that you might try is to measure your plane, then level your "z" axis and then if you know the nominal for all the holes create however many "auto vector points" you need and enter the nominal data for each hole. Make sure the "comp" is turned off and measure all the auto vector points that you created. Then do a new alignment; do a Best Fit (type 2D, 2D plane Z plus). This will only best fit the X and Y nominals of the auto vector points in your pattern. This normally works better for a pattern because you are taking out the error of your rotation through two points that may have a lot of included error. Say if your hole 1 is at -.002" on the X side and your other hole is +.005 on the X side, then you are including that degree of error into your coordinate system. Sometimes it is better to try a variety of methods to see if they repeat themselves, and to see which one works best for your application. If one of the holes is your origin then after the best fit alignment origin your coordinate system on that point and see what your pattern of holes deviate to there origin point. Hope this helps.
