Looking to dive into SPC of a stamping process;
The end result is a welded Aluminum part.
We stamp one half in the morning conduct a tool swap (changeover) and stamp the opposite half in the afternoon.
Reading through the various books about SPC our process is considered a short run. Since collecting the data would not be complete to after the run is finished.
Based on the General guidelines I would need to complete 12 subgroups of 5, collecting every half hour.
The Key Path variable I want to study is the profile of the flanges, the profile has a direct affect on the welding operation when the halves are welded together.
Creating a program and accurately measuring this profile would take our only CMM offline to other product.
Does anyone have ideas on completing this study? Or is there a better option that i missed?
