MSA for wire crimp pull test

Hello I am currently conducting an MSA study for wire crimp pull test using. I'm still a university student and this is the fist time doing destructive tests. I've already read some posts on this website but I still haven't figured out how to do this. Since its automatic/motorized. There is no need for operators, I was told that for every Gage R&R I need at least 3 operators, 10 pieces and 2 replicates.
What happens with the operators in this case?
Is there a full guide to do a complete guide for this type of MSA??

There are several things to consider in this scenario, some of which you questioned and some of which you have not:
  • Need for operators - the pull test is not 100% automatic. Operators can have a lot of influence in the results in how they prepare the samples, load the samples into the jaws, connect the extensometers, interpret the results, etc.
  • Destructive tests should be analyzed using a Nested MSA study
  • How do you plan to collect the samples? Split specimens?
  • See this white paper from Instron for some alternative ideas for MSA on a tensile/compression tester.
