What are PPK, PP, CPK and CP? When it comes to data collection software and statistical analysis , you may feel like you are eating alphabet soup when you see all of the acronyms. A value of 1 indicates the process variation exactly equals the tolerance. A %Tolerance greater than 30% is considered unacceptable. • Variability can be stated as either short-term or long-term. This should make Cpk comparable to Cp. A Cpk that's less than 1. So, if cp = cpk, then the distribution is absolutely symmetrical. 72 while Cpk of drilling process also increase from 0. When the distance from the mean to the nearest specification limit is considerably greater than the one-sided process spread, Cpk is high. and since the maximum value for k is 1. Scenario 1 Consider a process as shown in figure 1. Now that we have a way to calculate kurtosis, we can compare the values obtained rather than shapes. If the density of the liquid is greater than the density of the solid the body will float. Er, yes it will, it will force Datapage to calculate the Cpk (Ppk) to the upper limit (positive TP tolerance) because that WILL be the closest limit for it to calculate the value to since the average will ALWAYS be greater than zero. If Jill is boring an I. Cp is the amount of variation in your process - Cpk is the amount of variation in your process and where in relation to the mean the process is. 67 indicates that the proc ess is highly capable. The difference is due to the fact that in the first case, the gas changes its volume (expands). But unlike Cp, Cpk compares the distance from the process mean to the closest specification limit, to about half the spread of the process (often, the 3-sigma spread). Schedule Performance Index (SPI) and Cost Performance Index (CPI), like variances, allow you to assess the health of a project. Figure 1 illustrates how the net build premise is flawed based on an analysis of 13 independent sheet metal door assembly processes.

I never said "generally Cpk is greater , but sometimes Ppk can be greater !" Sometimes when the samples are taken over too narrow of a time span the calculations will cause Cpk to be slightly less than Ppk but this is an anomaly of using range to calculate Cpk. To be reasonably confident that a set of results will achieve a specific Cpk index, the range of result needs to be about 35 percent of the total tolerance and the average of the results targeted to less than 10 percent of the tolerance away from the nominal. Generally this means that the value of Cp or Cpk is at least 1. Other factors will help determine what may have caused the CPK level to elevate. The mean (38. 0005 inches.
