Abstract
A high-feed milling tool assembly includes a tool and a ramping insert. The ramping insert includes ramping, feed and side sub-edges. The ramping and feed sub-edges are longer than the side sub-edges and converge with increasing proximity to the side sub-edge to which they are both connected.
Claims21
A ramping insert comprising:
- opposing first and second rake surfaces;
- an insert peripheral surface connecting the first and second rake surfaces;
- an insert screw hole opening out to opposing sides of the insert peripheral surface, the insert screw hole having an insert screw hole axis;
- and
- first and second cutting edges extending along an intersection of the insert peripheral surface and a corresponding one of the first and second rake surfaces;
- each of the first and second cutting edges comprising:
- a first ramping sub-edge;
- a first side sub-edge;
- a first feed sub-edge connected to the first ramping sub-edge and the first side sub-edge;
- a second ramping sub-edge connected to the first side sub-edge;
- a second side sub-edge connected to the first ramping sub-edge;
- and
- a second feed sub-edge connected to the second ramping sub-edge and the second side sub-edge;
- wherein:
- each of the ramping and feed sub-edges is longer than each of the side sub-edges;
- a maximum rake surface length of each rake surface is measurable between the first and second side sub-edges thereof, and
- each of the ramping and feed sub-edges converge with increasing proximity to the side sub-edge to which they are both connected.

A high-feed milling tool configured for rotating about a rotation axis in a rotation direction, the rotation axis defining forward and rearward directions, the tool comprising:
- a tool end surface and a circumferentially extending tool peripheral surface extending rearward therefrom;
- a flute formed at an intersection of the tool end surface and the tool peripheral surface and extending rearward therefrom;
- and
- an insert pocket formed at an intersection of the tool end surface and the tool peripheral surface and opening out to the flute, the insert pocket comprising:
- a pocket back surface extending inwardly from the tool peripheral surface and facing the rotation direction;
- a pocket side surface extending from the pocket back surface to the flute and facing outwardly;
- a pocket top surface extending inwardly from the tool peripheral surface to the pocket side surface, and also extending from the pocket back surface to the flute;
- and
- a pocket screw hole opening out to the pocket top surface;
- wherein:
- the pocket back surface comprises a back abutment sub-surface;
- the pocket top surface comprises first and second pocket top sub-surfaces;
- the first pocket top sub-surface is adjacent to the tool peripheral surface and extends more in the forward direction with increasing proximity thereto;
- the second pocket top sub-surface is adjacent to the pocket side surface and extends more in the forward direction with increasing proximity thereto;
- and
- the first and second pocket top sub-surfaces extend more in the forward direction with increasing proximity to the flute.
