Cpk può essere calcolato in processo con un solo limite di specifica; normalmente Ppk è accettabile se superiore a 1,67. Influenza del sistema di misura sui valori di capability. Anche il sistema di misura utilizzato per raccogliere i dati di processo ha una sua influenza. The process capability index, also known as the process capability ratio. It is the ability of a process to produce output within specification limits, which is referred as Cp Potential and Cpk Capability Index. Given here is the process capability index formula to find the potential of a process, which is the process capability index.

Statistical tools Cp and Ck are used in quality management to ensure production processes meet defined specification limits. Cp measures process capability with respect to specification. Cpk measures process variation with sample mean, Taking periodic samples determines process capability. Statistical Process Control 1 Introduzione SPC si occupa del miglioramento della qualit`a. I metodi per il miglioramento della qualit`a possono essere applicati a qualsiasi area in una fabbrica o. A Cpk calculation is a vital tool to use when determining the capability of a manufacturing process. Managers use the Cp ratio and the Cpk formula to make sure a process has the ability to produce products that meet customers' specifications without having an unacceptable amount of defective items. Find out what Cp, Cpk, Cm, Cmk and control limits are. Statistical Process Control SPC Cp capability process The Cp index describes process capability; it is the number of times the spread of the process fits into the tolerance width. The higher the value of Cp, the better the process.
