Process Capability Index
Process Capability Index is used to find out how well the process is centered within the specification limits.It is denoted by Cpk.
Cpk = Cp(1-K)
Where,
Cp = Process Capability
K = 2(Design Target – Process Average) / (USL – LSL)
Design target is the actual specification targetted without +/- allowance.
