Note the main parameters for reference3. When the process is stable run the tool for 10 hours3. Take 5 parts out from each cavity every half hour and mark them with time, date and cavity. Total 20 sets of 5 parts from each cavity must be made, or according to agreement. the last sample lot note the main process parameters for reference and record the main functional characteristics (white diamonds) data into the NMP data collection spreadsheet!See DMY 00019ENClassification and Marking of Functional CharacteristicsTimeDimensionSubgroup size n = 5Number of subgroups N = 200,5 hours between samples takenNote: For clarity, only 6 subgroups are shown46 169。 NOKIA 2023 Data Collection Sheet ()47 169。 NOKIA 2023 Data Collection Sheet ()48 169。 NOKIA 2023 Graphical Presentation: Histogram?

Cpk values are not definite numbers as they are based on relatively small samples of a population.? The 95% confidence interval determines the interval which includes the true Cpk value with a probability of 95%, . there is a probability of 5% that Cpk is either lower or higher than this confidence interval.95% confidence intervalActual cpkCpk upper confidence limitCpk lower confidence limit54 169。 NOKIA 2023 Confidence of CpkSmall sample sizes gives wide confidence intervals55 169。 NOKIA 2023 Cpk Confidence Limits with a sample size of 100 and a nominal Cpk of 56 169。 NOKIA 2023 質(zhì)量系統(tǒng)推薦57 169。 NOKIA 2023 v 太友科技質(zhì)量控制系統(tǒng)產(chǎn)品系列 數(shù)據(jù)采集 數(shù)據(jù)分析 控制 /反饋 集成 /分析MiniDataRT MiniData MiniSPC TYSPC企業(yè)版自動(dòng)在線監(jiān)控 簡(jiǎn)單易學(xué) ,實(shí)用 幫助快速實(shí)施 SPC,代替EXCEL的理想工具功能 :生產(chǎn) ,品質(zhì) ,來料 ,投訴 ,圖表 ,查詢 ,數(shù)據(jù)導(dǎo)出 … ,全面控制58 169。 NOKIA 2023 v 設(shè)備 /儀器實(shí)時(shí)監(jiān)控分析程序（ MiniData – RT 實(shí)時(shí)監(jiān)控程序） 本方案適合測(cè)量設(shè)備 /儀器，連接單臺(tái)電腦，只要系統(tǒng)中已存在 * .txt格式的數(shù)據(jù)文件，只需要幾分鐘就能馬上實(shí)現(xiàn)數(shù)據(jù)的即時(shí)監(jiān)控和分析。數(shù)據(jù)即時(shí)采集，分析，導(dǎo)出，打印，和自動(dòng)存儲(chǔ)。59 169。 NOKIA 2023 v MiniData 數(shù)據(jù)分析工具（提供免費(fèi)普及版下載 ) 60 169。 NOKIA 2023 v MiniSPC 助你方便快捷地完成 SPC的推行61 169。 NOKIA 2023 謝謝觀看 /歡迎下載BY FAITH I MEAN A VISION OF GOOD ONE CHERISHES AND THE ENTHUSIASM THAT PUSHES ONE TO SEEK ITS FULFILLMENT REGARDLESS OF OBSTACLES.
