UCLr represents the limit of individual Rs . Circle those that are beyond this limit. Identify the cause and correct.Repeat three readings using the same appraiser and unit as originally used or discard values and re- average and recomputed it and the limiting value from the remaining observations. Acceptance Criteria: (2)In report：All calculations are based upon predicting 5.15 sigma ( 99.0 % of the area under the normal distribution curve ). K1 is 5.15/d2 *, where d2 * is dependent on the number of trials(m) and the number of parts times the number of operators (g) which is assumed to be greater than 15 . K 2 is 5.15 / d2 *, where d2* is dependent on the number of operators ( m) and (g ) is 1 , since there is only one range calculation. K 3 is 5.15 / d2 *, where d2* is dependent on the number of parts ( m) and (g ) is 1 , since there is only one range calculation.
