Hey everyone,
I've got one of these:
http://www.shars.com/horizontal-and-vertical-precision-5c-collet-index-fixture
And I'm using it to make circumferential slots in a part with an end mill; plunge milling to start the slot, and then slowly indexing it to form a few circumferential slots.
When you've completed the entire circle, the spot at the beginning of each slot where the plunge was initiated is ever-so-slightly to one side compared with the rest of the slot; as though somehow the part is pulling forward for the moment of the plunge, and then once the (side) milling commences, the part is pulled backward, making a slopply slot.
Any ideas what I should/could do to fix this?
