Does anyone have an Excel based simple SPC sheet that would give Cpk, CP, Ppk, Pp and would allow me to choose the subgroup size? This would be for simple cap studies. It would be nice if it showed a histogram or X-bar & R chart. I can export measurements from the vision system to an Excel sheet easily. I just need to copy the data and paste it to the above. Does anyone have any ideas? Of course, we are on a tight budget and don't want to purchase new full SPC software. Ours is Dos based and is ok except for copy and paste. Thanks.
