Process Performance is only used when process control cannot be evaluated. A company producing kitchen worktops, specified the length of one range at 120 cm ± 0.25 cm. Cp and Cpk Process Capability Metrics; Cp : How well the data would fit within the spec limits (USL, LSL) Cpk : How centered the data is between the spec limits. The Process Capability for a stable process, typically defined as ((USL-LSL)/ (6 x Standard Deviation)). ; If Cp = Cpk the process is centered at the midpoint of the specification limits. Developed by industrial statisticians using proven methodologies for quality analysis and control, InfinityQS solutions are saving leading manufacturers millions of dollars each year. Capability vs. control. Instructions A process is said to be in control or stable, if it is in statistical control. The process center is stable enough to perform capability analysis. This often happens with a mature process that has been around for a while. If you also do not have expert knowledge of "process capability", do not expect to get an education about it here. Process capability studies calculate the process capability indices Cp and Cpk. This prediction enables us to “qualify" a new manufacturing process as being fit for use in production. Difference Between Cp and Cpk . Capability (Cp) and performance (Cpk) charts illustrate a process’s ability to meet specifications. As with all the process capability indices, the process must be in control before assessing capability. print: a logical value indicating whether statistics and capability indices should be printed. The SPC control chart information is often used to visualize process capability. Now consider a variation. Process Capability Index (Cpk): → In Six Sigma Projects or any other quality improvement project, this tool is very useful for an estimate of the capability. a) the process capability ratio is a ratio for determining whether a process meets design specifications. The frequency distribution diagram called Histogram and Control Charts is the basic 7 QC Tools that are used to measure, … Cp and Cpk both give the process capability, while Cp talks about the data spread and width of the data range, the Cpk talks about the data points near to mean. Please feel free to contact me, if you have some suggestions to improve this page (roland.schnurr@sixsigmablackbelt.de). The index Cp provides a measure of potential process capability i.e. These can be analyzed statistically; where the output data shows a normal distribution the process can be described by the process mean (average) and the standard deviation. Cp > 1 Process is capable (product will fit between the customer's upper and lower specification limits if the process is centered). If it is not, can the process be adjusted to make it capable? Process Capability Analysis for Normal Distributions CP and PPM interpretation The Figure below shows control charts for a process. This prediction enables us to “qualify" a new manufacturing process as being fit for use in production. Verify that process variability is stable. To determine process capability, an estimation of sigma is necessary: (IR is an estimate of process capability sigma and comes from a control chart. The process Capability Study will compare the process specification to the process output and determine statistically if the process can meet the customer’s specification. Use Cp Cpk : When you have a sample, not the population, and are testing the potential capability of a process to meet customer needs. Once statistical process control is evidenced, then the histogram and process capability may be analyzed. 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. ... We determine whether or not a process is in control by using either a run chart or control charts, with control charts being the preferred method. Therefore, only use Process Capability charts if the process is in control for an extended period. respect to base and total enamel thickness . It is a measure of the uniformity of a process that makes a product. characteristics. Process Capability Indices. Once the process is operating in control, capability analysis attempts to answer the question: Is the output meeting specifications, or is the process capable?
