    Hi All,
    I’ve been given the task of performing MSA on a destructive measurement process on Torque Gauge. I have no experience in this area, so please correct me if anything I’m saying is wrong. from my searching, I have to use Nested Gauge R&R for destructive testing. Here are my situation now:
    1. My company have a torque gauge for measuring torque. this gauge is used to be manually twisted by the operator. Now, we had modified so the operator just put the object and let the machine twisting the cap (here, we use motor to twist).
    2. the speed of motor is fix (cannot be adjusted).
    3. This Torque Gauge is used for torque test of part.

    Here are some questions:
    – How I choose the sample that represent to this study?Should all the samples measured be from the same lot/machine?
    – What sample size do I need?
    – Do I still need operator variable?
    – What is the acceptance criteria for a Nested Gage R&R in destructive testing?

    I really appreciate any help from you. Please feel free to explain. Thank you so much

    1.How I choose the sample that represent to this study? Should all the samples measured be from the same lot/machine? ans…its better if your sample from different lot number
    2. What sample size do I need? ans…select the most critical size
    3.– Do I still need operator variable? ans…yes
    4.– What is the acceptance criteria for a Nested Gage R&R in destructive testing? ans,,,,50/50 meaning you have 50% failed and 50% pass and choice operator champion to do the testing on the same sample.

    Hi randy,

    thanks for your answer.
