• Can improve part quality and reduce manufacturing costs

Cp and Cpk are process capability indices used to assess the ability of a process to produce output within specification limits.

• Cp is a measure of process capability that compares the spread of the process to the width of the specification limits.

• Cpk takes into account the centering of the process within the specification limits as well.

• Higher values of Cp and Cpk indicate better process capability.

• For Cp, a value of 1...read more
