Cpm is a capability index, also known as the Taguchi capability index, that is a function of the specification limits, mean of the process, and a provided target, T. . The indices of Cpk and Ppk focus on centering of the mean of the distribution around the midpoint of the tolerances (USL+LSL/2) but this is not always the customer target.

The process capability index is calculated with the help of this below formula: In the below online process capability index calculator, enter the upper specification limit, lower specification limit, standard deviation and mean in the respective input boxes and then click calculate to find out the output.

The allowable spread is the difference between the upper and lower specification limits. The actual spread is 6 times the estimated standard deviation. The process capability is a measurable property of a process to the specification, expressed as a process capability index (e.g., C pk or C pm).The output of this measurement is usually illustrated by a chronological control sample, histogram and calculations that predict how many parts will be produced out of specification (OOS). If your Process Mean (central tendency) is closer to the LSL, use: [x(bar) – LSL ] / [3 * R Bar / d2], where x(bar) is the Process Mean.

It relates to a process yield of 99.99% and a sigma level of 4.0, and so virtually all of the measurements are within the customer requirements. The process capability is a measurable property of a process to the specification, expressed as a process capability index (e.g., C pk or C pm).The output of this measurement is usually illustrated by a chronological control sample, histogram and calculations that predict how many parts will be produced out of specification (OOS). The process capability calculation would over-estimate the defect rate if the data were used in this form. When data follows a well-known, but non-normal distribution, such as a Weibull or log-normal distribution, calculation of defect rates is accomplished using the properties of the distribution given the parameters of the distribution and the specification limits. Se hela listan på spcforexcel.com The process capability index is a statistical formula that businesses can use to see how their process is meeting the needs of their customers. The index is useful in letting businesses see where they might be able to make changes in their process if they want to make improvements.

In process improvement efforts, the process capability index or process capability ratio is a statistical measure of process capability: the ability of a process to produce output within specification limits. The concept of process capability only holds meaning for processes that are in a state of statistical control. Process capability indices measure how much "natural variation" a process
