Hello all
I am new and hoping that someone could help me. I am not familair with Cpk yet I am doing a capability study on perpendicularity. i know this is a one sided tolerance but the issue I am having is how do I incorporate a Maximum Material Condition (MMC)? My print spec is .015MM MMC.
The perpendicularity is reletive to a bore; at MMC my highest allowable Perp reading could be .035MM. I am not sure how to plot this; I am using SPC 4 Excel. Would I use .015 as my lower limit and .035 as the high? I would like to know if I am doing this the proper way. For a one sided Tolerance I think I would want to look at Cpu rather than Cpk? Any help would be highly appreciated.
