ANTI-ROTATION MOUNTING MECHANISM FOR ROUND CUTTING INSERT |
摘要 |
<p>An anti-rotation mounting mechanism is provided between an indexable insert and an insert-receiving pocket in the body of a machine tool, such as a milling cutter. The mechanism includes a plurality of curved stop surfaces uniformly disposed around the side surface of the insert, a portion of which is obliquely oriented with respect to the side surface of the insert, and at least one anti-rotation surface in the pocket of the tool body having a shape substantially complementary to that of the stop surfaces for forming an interference joint between the pocket and the insert. Both the stop surfaces and the anti-rotation surface are substantially defined by partial radius curves such that either a broad, line-type or lenticular contact between the anti-rotation surface and the obliquely oriented portion of one of the stop surfaces is achieved. The mechanism effectively prevents rotation between the insert and pocket without the formation of point-type, localized stresses which can chip or break the insert.</p> |
