The ‘k’ represents ‘centralizing factor.’ The index considers the fact and possibility of our data not being centered. Cp and Cpk calculates the consistency of our proximate average performance. Webb4 mars 2024 · Boiled down to the basest terms, it means that the distribution of your process variation (6 sigma) - centered at the process mean - only uses up 60% of the tolerance (USL-LSL) at the half of the distribution closest to the specification (the other half would use 60% or less). coleslaw cuisinart food processor
