Process capability this is a long article, but i thought it was important to keep cp and cpk together cpk is addressed first, then cp there are also crib notes on what the equations mean in a real performance sense, what you should be able to tell about a process depending on cp and cpk values and more.
Process capability refers to the capability of a process to consistently make a product that meets a customer specified specification tolerance capability indices are used to predict the performance of a process by comparing the width of process variation to the width of the specified tolerance. Process process capability is the long-term performance level of the process after it has been brought under statistical control it is the ability of the combination of your 5 m's to produce a product that will consistently meet the design requirements and the customer expectation. Process capability study and index, how to calculate cp & cpk process capability is mathematical & statistical study for determine the processes are performing by its natural variations and capability. Cpk is a process performance capability index that is used to determine if the natural process limits lie inside of the specification limits it is calculated using the minimum of.

Watch video in this video, dr richard chua explains how to calculate process capability in your six sigma project. When performing capability analysis using minitab one may seriously misrepresent the true capability of a process example consider the following simulation suppose the lsl = 37, the usl = 43, and our target for this process is midway between the. Process capability analysis--normal and general non-normal distribution (raw data) - quick tab select the quick tab of the process capability analysis--normal and general non-normal distribution (raw data) dialog box to access the options described here normal distribution use the options located under normal distribution to compute capability indices based on.
Simulate a sample from a process with a mean of 3 and a standard deviation of 0005 rng default % for reproducibility data = normrnd(3,0005,100,1) compute capability indices if the process has an upper specification limit of 301 and a lower specification limit of 299. When this occurs, transformation of the data will offer similar results for the process capability calculations done during both the define and control phases the analysis here illustrates the effect on long-term process capability calculations.
