Abstract
A tangential cutting insert having first and second opposing end surfaces and a peripheral side surface extending therebetween. First and second edges are formed at the intersection of the first and second end surfaces with the peripheral side surface. A groove in the peripheral side surface extends between and intersects the first and second end surfaces at first and second minor edges. In first and second opposing side views of the cutting insert, at least the first edge is generally concave.
Claims15
A tangential cutting insert comprising:
- first and second opposing end surfaces and a peripheral side surface extending therebetween;
- first and second peripheral edges, respectively, formed at the intersection of the first and second end surfaces with the peripheral side surface, at least a section of the first peripheral edge forming a major cutting edge;
- at least one groove in the peripheral side surface extending between and intersecting the first and second end surfaces at said first and second peripheral edges, respectively;
- wherein, in first and second opposing side views of the cutting insert, at least the first peripheral edge is generally concave;
- and
- wherein, in an end view of the cutting insert, the major cutting edge comprises two straight line portions interrupted by the at least one groove.
A milling cutter comprising an annular cutter body having a plurality of identical segments equally spaced about an inner circumference of the cutter body, each segment having seven cutting inserts secured thereto, wherein each cutting insert comprises:
- first and second opposing end surfaces and a peripheral side surface extending therebetween;
- first and second peripheral edges, respectively, formed at the intersection of the first and second end surfaces with the peripheral side surface, at least a section of the first peripheral edge forming a major cutting edge;
- at least one groove in the peripheral side surface extending between and intersecting the first and second end surfaces at said first and second peripheral edges, respectively;
- wherein, in first and second opposing side views of said each cutting insert, at least the first peripheral edge is generally concave;
- and
- wherein, in an end view of said each cutting insert, the major cutting edge comprises two straight line portions interrupted by the at least one groove.
