David,
You can use the following formula:
=MIN((A3-A1)/(3*A2),(A1-A4)/(3*A2))
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.
Of course, be careful when you have a one sided tolerance. In that case, use only the appropriate half of the calculation.
For example for a max tolerance (i.e. 0.005 Flatness): use only Upper Spec half of the calculation
=(A3-A1)/(3*A2)
Hope this helps.

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.

Mark,
If you send me your email address, I can forward the code. I will forward it as text only for you to place in a macro in Excel. Recent email security devices strip out attachments with macro code.
