Since this value is less than one, this process is not acceptable because a large portion of the production falls outside the upper specification and is considered defective. Here, the Cpk calculation is lesser or 0.43. To calculate the Cpl, subtract the lower specification limit from the mean, then divide this by 3 times the standard deviation (SD):Ĭpl = \ The Cpk equations for each are nearly identical. The Cp for the upper limit is represented as the Cpu, while the Cp for the lower limit is represented as the Cpl. On the other hand, the process capability index lets you know where your process is in relation to the center of those specifications. Process capability index measures your process to see if it is capable of making an item within the given specifications. The Process Capability Index comes in handy while solving the estimation of products in a real-life situation.Ĭpk is a measurement of process capability. All in all, it provides important information about the stability of the process that is expected to be uncertain with ever-changing variables. When this process is expressed in a single number by the use of the Process Capability Index (Cpk) it gets easier for users to meet the specifications. The Whole process is responsible for understanding and meeting customer requirements, engineering tolerance and specifications of manufacture of produced goods. The outputs are obtained in the plus and minus deviations. This method is utilized by both established production units and startups. The data of production conditions, materials and people involved in the process is taken into consideration. Usually, three measured output data is used. But it differs in the terms of using a control chart analysis to check the statistical control of the data. It is somewhat similar to 'mean' or 'average value' and the 'standard deviation' that is taught in arithmetics. The inputs for the process capability index are usually the normal statistical analysis and distribution of data obtained. They wanted to estimate the possible output they are going to have to calculate and manage the resources for maximum performance. Later the investors tried to make calculations based on the observed speed of factors of production. After the industrial revolution that introduced machine lines for production, the method of manufacturing turned into a controlled process. Process Capability is a calculation tool used by many to estimate the product output. Let us study the basics of cpk and cpk formulas. Cpk gives you the best-case scenario for the existing process. Cpk is used to calculate how close you are to a given target and how consistent you are to your average performance. It measures the producer's capability to produce a product within the customer’s tolerance range. And Cpk stands for Process Capability Index (Cpk). CP stands for Process Capability (Cp), it is a technique to find out the measurable property of a process to a specification.
