If you have a part with a large bore through the middle, how do you set up to machine a hole exactly perpendicular to the axis of that bore?
I imagine that this is quite a common problem, so must have a common solution? My particular setup puzzle is analagous to this, except that I will be using the horizontal spindle. Machining this casting: https://goo.gl/photos/6QhNnqjzRuSJJpva7 The order of operations will be, starting with the raw casting: 1) with the large flat face clamped down to the table machine the base flat. 2) Now clamp the base to the table, face off the large flat face and machine the large bore. 3) Return to the original setup and machine a key-slot in the base _exactly_ on the axis of the large bore. 3) is the problem. I can indicate the base to make sure that is perpendicular to the spindle axis, but how do I make sure that the bore axis and the spindle axis intersect? -- atp "A motorcycle is a bicycle with a pandemonium attachment and is designed for the especial use of mechanical geniuses, daredevils and lunatics." — George Fitch, Atlanta Constitution Newspaper, 1916 ------------------------------------------------------------------------------ Check out the vibrant tech community on one of the world's most engaging tech sites, Slashdot.org! http://sdm.link/slashdot _______________________________________________ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users
