There are Five Cp Cpk Worksheets in the Template

  • Cp Cpk 8 Worksheet - for up to 8 Characteristics with 100 measurements each
  • Cp Cpk 35 Worksheet - for up to 35 Characteristics with 100 measurements each
  • Attribute Cp Cpk Worksheet for Go/No-go data - for pass/fail (binary) data where there are no measurements.
  • Cp Cpk True Position - when there are two aspects to your measurement (e.g. horizontal and vertical for the position of a hole.)
  • MMC Cpk True Position - when you are measuring something like the inside and outside of a cylinder

USL & LSL = Nominal Value (+)(-) Tolerance

To calculate your Upper and Lower Specification Limits, provide your Nominal Value (+)(-) Tolerance (USL = Nominal Value + Tolerance, LSL = Nominal Value - Tolerance).

Once you have inputted your USL & LSL into the template, input your data - your Process Capability Metrics will then start calculating automatically (a minimum of 2 data values are required).
