適用范圍：This part of ISO 22514 prescribes the steps to be taken in conducting short-term performance studies that aretypically performed on machines where parts produced consecutively under repeatability conditions areconsidered. The number of observations to be analysed will vary according to the patterns the data produce,or if the runs (the rate at which items are produced) on the machine are low in quantity. The methods are notrecommended where the sample size produced is less than 30 observations. Methods to be used for handlingthe data and carrying out the calculations are described. In addition, machine performance indices and theactions required at the conclusion of a machine performance study are described.The document is not applicable when tool wear patterns are expected to be present during the duration of thestudy, nor if autocorrelation between observations is present. The situation where a machine has captured thedata, sometimes thousands of data points collected in a minute, is not considered suitable for the applicationof this part of ISO 22514.
