Measurement System Analysis ;何謂量測系統;何謂量測系統;何謂量測系統;討論問題﹕;量測系統分析的目的;量測系統分析的目的;量測系統分析的做法; 計數值G RR (Go-Nogo) ;(1)測試設備內部之一致性能力評估;量測系統分析的做法-Variable GRR; 計量值G RR ;P/T值的計算;對10個部品進行量測, 部品的規格為5.0 ±0.1mm;再現性:;再生性:;量測系統的變異;量測結果的分析，是基於每個因素對總變異或公差所佔的百分比。計算百分比時，公差可能會以總變異當作分母。;零件的變異;總變異;用Minitab 計算GRR;計量值GRR;計量值GRR;;;Source DF SS MS F P Sample 9 0.0432483 0.0048054 79.5982 0.00000 Operator 2 0.0012133 0.0006067 10.0491 0.00117 Operator*Sample 18 0.0010867 0.0000604 2.4148 0.01585 Repeatability 30 0.0007500 0.0000250 Total 59 0.0462983 Gage RR %Contribution Source VarComp (of VarComp) Total Gage RR 7.00E-05 8.13 Repeatability 2.50E-05 2.90 Reproducibility 4.50E-05 5.23 Operator 2.73E-05 3.17 Operator*Sample 1.77E-05 2.05 Part-To-Part 7.91E-04 91.87 Total Variation 8.61E-04 100.00 StdDev Study Var %Study Var %Tolerance Source (SD) (5.15*SD) (%SV) (SV/Toler) Total Gage RR 8.37E-03 0.043088 28.52 6.84 Repeatability 5.00E-03 0.025750 17.04 4.09 Reproducibility 6.71E-03 0.034547 22.86 5.48 Operator 5.23E-03 0.026916 17.81 4.27 Operator*Sample 4.21E-03 0.021658 14.33 3.44 Part-To-Part 2.81E-02 0.144827 95.85 22.99 Total Variation 2.93E-02 0.151101 100.00 23.98 Number of Distinct Categories = 5 ;GRR的評价要看這里;計量值GRR;QA;QA;QA;Thanks!;1、有时候读书是一种巧妙地避开思考的方法。六月-20六月-20Saturday, June 27, 2020 2、阅读一切好书
