I'm rusty at capability, so I figure I will go to the experts here.
I've got a fineblanked stamped steel part with two holes in it. One receives a fitting that gets brazed in place. The other is a mounting hole for a bolt. The fitting hole is the only important feature. I've only got a .003" tolerance band on it, so I'm dead on a capability study using calipers since I don't even have enough resolution. Besides that, our biggest issue has been burrs that prevent the fitting from being inserted for brazing. For this reason, I am implementing a go/no-go gage as the true test of a good part.
Apparently I have killed off the brain cells that tell me if I can do a capability study on attribute data. If so, how?
In reality my customer will accept a capability study on any feature as long as it hits 1.67 cpk. I'm trying to break this place out of the "doing paperwork to prove we know how to do paperwork, even if it is pointless" mode, so I hate doing stuff like this.
Thoughts?
