Process Capability Between and Within Capability

Hi together,

 

I want to check the capability of multiple quality characteristics thorugh the capability process platform.

The different quality characteristics are controlled by different control chart types.

So, for some is the IMR chart appropriate, for others the three way chart X-MR-R and also for some is the X-MR-s chart used.

 

My objective is to illustrate all the characterisitcs in one process performance plot.

 

Is it possible to calculate the between-and-within capability using the Average of ranges (X-MR-R chart characterisitcs) and the average of unbiased standard deviations (X-MR-s chart characteristics)? So, is there a way to nest the within subgroup variation statistic in this platform.

 

Many thanks in advance for your feedback!
