  • CPK - 2 Dimesions

    Dears,a "conceptual" question...If I have a characteristic identified by two factors and the specification limits are defined by an area rather than an interval... is it possible to calculate the CPK?See the diagram below (invented): blue dots = the specification, orange dots = production. 
    Is it possible to calculate a CPK?Thanks in advance for the feedback.
