Abstract
An indexable cutting insert for use with a cutting tool includes an insert body having a first surface and a side relief surface defining a cutting edge adjacent the intersection of the first surface and the side relief surface. A chip breaking structure is interposed between the first surface and the cutting edge. The chip breaking structure includes first and second series of wedges. Each series of wedges is disposed inwardly from the cutting edge and the wedge series are disposed in orthogonal or normal relation to one another. In a preferred arrangement, the narrow edges of the first and second series of wedges are aligned with one another.
Claims16
A cutting insert for use with a cutting tool that selectively removes material from a workpiece, the cutting insert comprising:
- an insert body having a first surface and a side relief surface defining a cutting edge at an intersection of the surfaces;
- a chip breaking structure on the first surface spaced inwardly from the cutting edge, the chip breaking structure including a first series of wedges disposed contiguous one another without a gap therebetween and a second series of wedges disposed contiguous one another without a gap therebetween and substantially orthogonal to the first series of wedges.
A cutting insert with chip control features comprising:
- a body having a first surface, a side relief surface extending generally orthogonal to the first surface and a cutting edge defined adjacent an intersection of the first and side relief surfaces and in a plane spaced from the first surface;
- a peripheral land on the first surface extending inwardly from the cutting edge;
- and
- a chip breaker interposed between the land and the first surface and including first and second series of wedges disposed contiguously without a gap therebetween, said first and second series of wedges disposed in generally orthogonal, contiguous relation to one another for control of chips generated from a cutting operation.
