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. d2 values are from Appendix E.
AV - If a negative value is calculated under the square root sign, the appraiser variation ( AV ) defaults to zero ( 0 ).
K2 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.
K3 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.
d2* is obtained from Table D3, "Quality Control and Industrial Statistics," A. J. Duncan ( See Appendix H,
Reference 9 ).
參考答案:所有演算根据预言5.15 斯格码(99.0% 区域在正常分配曲线之下) 。K1 是5.15/d2, d2 依靠试验(m) 的数量并且零件的数量计时被承担是大于15 操作员(g) 的数量。d2 价值是从附录E 。AV - 如果消极价值被计算在方根标志之下, 评价人变异(AV) 默认到零(0) 。K2 是5.15/d2 *, d2 * 的地方依靠操作员(m) 的数量并且(g) 是1, 因为有只一范围演算。K3 是5.15/d2 *, d2 * 的地方依靠零件(m) 的数量并且(g) 是1, 因为有只一范围演算。d2 * 被获得从表D3, "质量管理和工业统计," A. J. Duncan (参见附录H, 参考9) 。
