OK, Let's say it's a 300 Piece Study. What are the rules of remeasuring or refixturing or replacing a part that is considered a flyer by the data.........
You cannot ignore a part that is flyer unless there is a legitimate reason. By your questions about refixturing, it appears that you suspect that the part was incorrectly loaded into a measurement fixture, or there was debris between the part and fixture that threw the reading out. In a case such as these, you could legitimately clean the fixture, remeasure the same part and substitute the results.
However, in another example, this would not be true. Let's say that during the manufacture of product, a change occurred (material lot, etc.), the process shifted, then was adjusted back. In this example, the "flyer" is a legitimate part of the data that is telling you that the process is not always in control. You cannot simply throw this data out. You have to bring the process into control and re-study.
