Hi,

Has someone a R&R file ( Excel or any other format ) avaible in order to send it me?

K2 in GRR Form

Hi,
In the GRR form, K2 is the constant used to calculate reproducibility,

reproducibility(raw)= (5.15*people variance)/d2

For 2 appraisers, d2 is 1.41,

May I know where does 1.41 come from?

Thank you very much.

Re: K2 in GRR Form

The Square root of 2 is 1.41 (1.414213562²=2)
Therefore, with 3 appraisers d2 is 1.732, with 4 appraisers d2 is 2, and so on.

d2* Table

The constant d2* (Dee-Two-Star) is read from the Table called "Values for the distribution of the Average Range" given in the MSA Manual.

The values of d2* for reproducibility are:

For 2 appraisers : d2* = 1.41; K2 = 5.15/1.41 = 3.65
For 3 appraisers : d2* = 1.91; K2 = 5.15/1.91 = 2.70

Similarly, d2* used in repeatability calculations depends on No of trials and (No of parts time no of appraisers). So for
3 appraisers, and 10 parts we have the following d2* values:

for 2 trials : d2* = 1.128; K1 = 5.15/1.16 = 4.56
for 3 trials : d2* = 1.693; K1 = 5.15/1.72 = 3.04

For R&R calculations,

For 5 parts, d2* = 2.48; K3 = 5.15/2.48 = 2.08
For 10 parts, d2* = 3.18; K3 = 5.15/3.18 = 1.62

For statistical explanation of these values you will have to refer
"Quality Control And Industrial Statistics" by AJ Duncan.

Thanks for the explanation Atul, you can find more information about in on MSA (measurement Systems Analysis) Febr. 1995 Ford Motor Comp., GM Corp and D.C, , the manual may obtained from AIAG at 810-358-3570, the values in this manual are on page 29

Arte,

Yes, the MSA manual has the table. MSA manual also mentions Duncan's book as reference.
I use the values on faith that someone out there would have a valid statistical explanation for them - much like we 'look up' the constants A2, D3, D4... in SPC.
