Rejection Calculator

Invalid date

Customers and manufacturers use different methods to specify the quality required. Some of the methods used are percentage variation, Cp, Cpk, Z, percentage rejection, ppm rejection, ppb rejection etc.
The app then calculates the actual Cp, the actual Cpk and the actual Z values.
Another useful 'interpretation' is the estimated rejection levels. You come to know the estimated 'under size' and 'over size' rejection expressed as percentage and parts per million (ppm).
