The Process Capability Calculator helps determine how well a process can produce outputs within specified limits. It calculates the Cp (potential capability) and Cpk (actual capability) indices, which are critical for quality control and process improvement. Maintaining high Cp and Cpk values indicates a consistent and reliable process, ensuring better product quality and reduced defects.
The Cp index measures the potential capability of a process by comparing the spread of the process output to the specification limits. A higher Cp value indicates that the process variability is within acceptable limits, leading to consistent product quality.
The Cpk index considers both the process variability and how centered the process is between specification limits. A higher Cpk value reflects better alignment with quality standards, reducing the likelihood of producing defective products.
Enter the values above and click Calculate Cp and Cpk to obtain the results. The calculator will also provide feedback on whether the process is capable or not, helping to maintain and improve overall product quality.
