    Hi Miner,

    it is good to have your experitse in this forum. You stated that a crossed analysis is not possible for destructive measurements.
    Is there a measure or guidannce which tells me that the parts are similar enough to carry out a crossed analysis?

    There is no real guidance. If your judgement is that the parts are homogeneous, and if you cannot perform a nested study (i.e., no software or template), you can perform a crossed study. That is better than no study at all. However, the results WILL be different than you would get from a nested study. If the gage is clearly good or clearly bad, the difference will not affect your decision. If the gage is borderline, this difference could affect your decision.
