Round wiper tooth and face mill incorporating the same

摘要

A milling tool includes a body which is rotatable about a first axis. At least one cutting tooth mounted on the body having a cutting edge for cutting about the first axis. A wiper tooth extends from the mill body. The wiper tooth includes at least at a portion having a peripheral surface about the second axis and the peripheral surface intersects a face surface defining a cutting edge that is round about the second axis for cutting about the first axis. In some embodiments, the peripheral surface, the face surface and the cutting edge are formed on an insert that is mounted the mill body.

1. A milling tool comprising:
a body, said body being rotatable about a first axis; at least one cutting tooth mounted on the body having a cutting edge for cutting about said first axis; and a wiper tooth comprising a round wiper cutting insert, said insert being round about a second axis and having a peripheral surface about said second axis; wherein said peripheral surface intersects a face surface defining a cutting edge that is round about said second axis for cutting about said first axis, wherein said wiper cutting insert cutting edge is formed along a first plane offset at a first angle relative to a second plane perpendicular to said first axis and below said first plane, wherein said first angle is formed along a third plane perpendicular to said first and second planes, wherein a body radius extends perpendicularly from said first axis, said body radius being tangent to said wiper cutting insert cutting edge, wherein said third plane is axially along a diameter of the wiper tooth cutting insert, wherein said third plane extends at a third plane angle relative to the body radius, said third plane angle being in a range of angles as measured from a wiper tooth radius extending perpendicular from said body radius in a direction of cutting to an angle less than 90° as measured from said wiper tooth radius in a direction outward toward the body radius, wherein the third plane intersects said cutting edge at a point, wherein said point is furthest axially from the second plane than any other point on said cutting edge.
