S

I have recently started to use minitab and since 3-4 weeks I have a problem.

We have a new machine in factory and products.

The problem is we don't know how to qualify machine as we don't know the limits related to our products. We would like to detemine product limits experimentally.

The machine has 3 palettes which carry products.

My boss demanded me to run R & R first, and I have run it 3 palettes, 10 samples, 3 times and I have the values.

Now, client demand me to find limit values of the products from obtained R & R results.

I can simply give them the mean value and 6*standart deviaiton as limits but my boss warned me that will be only valid for the samples that we have tested and there is a risque that we will not be correct in future.

At this point I need your help dear professionnals.

How can I determine limits from my R & R results in minitab and determine which samples are our of limit. As currently the machine has no limits, it can say all samples are good so I don't know which samples are good in this test conditions.

I need a setup of the limits first from R & R values and also determine if some of the samples in R & R study is good / bad according to those experimentally determined limits.

For information, I am totally beginner in this minitab subject and statistical analysis. So, please help me and with specific explications so that I can understand.

Thank you very much.

Sincerly.
