Tīmeklis2024. gada 9. janv. · Il Controllo Statistico di Processo (SPC) consiste in un set di test statistici eseguiti su un processo (ad esempio una linea di produzione). I suoi obiettivi sono. Tenere sotto controllo la qualità del processo. Prevenire errori. Ridurre i costi dovuti a problemi riscontrati su unità di produzione non conformi. TīmeklisSQCpack is complete, easy-to-use SPC software that can produce control charts, Cpk analysis, histograms, and other SPC analysis charts. Should you calculate Cpk when your process is not in control? If a process is unstable, capability analysis will be unreliable. If special causes are present in the control chart, the Cpk value should …
