    Hi,

    In my company we tried to introduce a Gage R&R and cp, cpk indices to control our production and measurement system. Problematic issue is the fact that no one knows how to do this correctly…

    I have read a few articles about this topic so far, but still this is not clear for me.
    Please correct me if I am wrong.
    I want to use cp, cpk, pp, ppk indices to control company production, how far from spec limits we are, etc.

    Also I want to introduce a Gage R&R type 1 to verify a measurement system. Type 1, because to start a calibration of our product (wind sensor) operator needs to press only a start button (so there are no variation between operators).

    For a Gage R&R type 1 I want to use 1 unit and measure it 30 times, in this way I will have information about repeatibility. Can I add also 30 measurements of 30 different units (1 measurement per 1 unit) to get information about reproducibility?

    I have problem with my outputs (in the attachments you can see graphs from minitab)

    In TunnelDAta.xlsx you could find measurement data in two columns:
    First – measurements of 30 units,
    Second – 30 measurements of the same unit.

    in Gage R&R type 1 I dont see any condition for NDC, can I use this data ?

    Thank you for any help.
    Regards
