Corner Edge Finding Cylinder

Could have used it today on an angled fixture part I was doing .Instead I left extra material, drilled a hole in the extra material, reamed the hole and then stuck a gage pin in it. Then I used the pinned hole to pick up my tool height for the next operations. I also indicated the pinned hole with my Zero It (pin was parallel with the Y axis) and then moved the known distance (which I determined in Mastercam X2 MR2) to the chamfered edge and set my x origin.

I believe I've mentioned before that an assortment of Tooling Balls can sometimes be beneficial in single angle (and especially compound angle work).

May not be exactly the same situation but I sometimes use a different way to pick up datum's for angled or compound angled holes. I take a ballnose and plunge a dimple in the surface of a part with the center of the ball being my 0 point on the surface. Then I put a ball bearing in the dimple and indicate it with the head under desired angle. Works perfect. Jerry

Jerry:

That's pretty ingenious. It would work especially well when you can't drill a hole for a tooling ball but have enough material coming off your surface to make your "detent". I suppose you could super glue the ball in the dimple for indicating at an angle (so you wouldn't have to hold it in place), and just whack it free when you're done.
