David, You can use the following formula: MIN((A3-A1)(3A2),(A1-A4)(3A2)) where A1 is the cell that contains the process average A2 is the cell that contains the process standard deviation A3 is the cell that contains the Upper Spec Limit A4 is the cell that contains the Lower Spec Limit. In that case, use only the appropriate half of the calculation. For example for a max tolerance (i.e. Flatness): use only Upper Spec half of the calculation (A3-A1)(3A2) Hope this helps.

Could someone please let me know if there is a formula for calculating the CPK in Excel, and if so, what the formula is, I would really appreciate it 0 September 27, 2001 at 4:00 am 68935 Savage Participant Matt Include Matt in your post and this person will be notified via email. ![]() By attaching the visual basic module to a new, blank worksheet and saving this worksheet as your start-up template (see Excels online help for detailed instructions), you can have these formula readily available in every new worksheet you make. The only downside to this approach is the fact that user-defined functions are viewed as macros by Excels macro-checking device. Excel will catch the defined functions (as macros) everytime you, or someone else, opens your worksheets if you have this macro-checking option set. If interested, I can email you the.bas Visual Basic module containing the user-defined functions. You simply import this module using Visual Basic Editor under the ToolsMacro menu. The functions are recognized by Excels Paste Function (the fx button on the main toolbar). This is helpful the first few times you use them in order to learn the arguments (cell references) necessary to perform the calculations.

If you want me to email you a copy of the VBA module containing my Cp and Cpk user-defined functions, please send a separate request via email to email protected. Please, include your email address explicitly.

Matt, I know its been a while but is there any chance you can e-mail me the visual basic information. Im currently using SPC to chart this data but having this information would make life so much easier.
