All calculations are based upon predicting 5.15 sigma (99% of the area under the normal distribution curve).AV - If a negative value is calculated under the square root sign, the appraiser variation (AV) defaults to zero (0).

ANALYSIS:

R&R<=10%: MS ACCEPTABLE, 10%<R&R<=30%:MS MAY BE ACCEPTED WITH PROPER JUSTIFICATION, R&R>30%: MS NOT ACCEPTABLE, NEEDS IMPROVEMENT.

REAPEATABILITY RANGE CHART: ALL RANGES MUST BE WITHIN CONTROL LIMITS. IF ANY RANGE IS BEYOND THE LIMIT, DISCARD THAT DATA AND RECALCULATE THE LIMITSAPPRAISER AVERAGE CHART: AT LEAST 50% DATA SHOULD BE OUT SIDE OF CONTROL LIMITS. IF NOT MEASUREMENT SYSTEM IS NOT CAPABLE FOR MEASURING PART TO PART VARIATION

R&R: IF MS IS USED FOR SPC, CALCULATE R&R AS "% PROCESS VARIATION" OTHERWISE AS "TOLERANCE VARIATION".
