Abstract
Herein a cutting insert for a power skiving tool is disclosed. The cutting insert includes an insert body having a bottom surface extending in a first plane, and a body axis extending substantially in parallel with the first plane. The insert body has a cutting end portion and opposite thereto, an abutment surface. The abutment surface extends substantially perpendicularly to the body axis and to the first plane. The cutting end portion is provided with a first and a second cutting edge, the first cutting edge and the second cutting edge being directed in a same cutting direction. Herein, further a power skiving tool including such cutting inserts is disclosed.
Claims22
A cutting insert for a power skiving tool, the cutting insert comprising:
- an insert body having a bottom surface generally extending in a first plane and being configured to abut against a corresponding surface of the power skiving tool, an upper surface extending opposite to the bottom surface, and a body axis extending substantially in parallel with the first plane, wherein as seen along the body axis the insert body includes a cutting end portion and opposite thereto an abutment surface configured to abut against a corresponding surface of the power skiving tool, wherein the abutment surface extends substantially perpendicularly to the body axis and to the first plane, wherein the cutting end portion is provided with a first cutting edge and a second cutting edge, the first cutting edge and the second cutting edge being directed in a same cutting direction, wherein the first cutting edge extends along an edge portion of the upper surface and the second cutting edge extends in a second plane, the second plane being substantially parallel with the first plane and extending between the upper surface and the first plane, and as seen along a normal to the first plane at least a portion of the second cutting edge extends from the insert body beyond the first cutting edge.
A rotatable power skiving tool comprising:
- a generally circular tool body having a center axis about which the power skiving tool is rotatable, the tool body including a number of peripherally arranged insert seats arranged on one side of a reference plane, the reference plane extending perpendicularly to the center axis, wherein the insert seats face away from the reference plane;
- and
- a cutting insert arranged in each of a respective insert seat, the cutting insert including an insert body having a bottom surface generally extending in a first plane and being configured to abut against a corresponding surface of the power skiving tool, an upper surface extending opposite to the bottom surface, and a body axis extending substantially in parallel with the first plane, wherein as seen along the body axis the insert body includes a cutting end portion and opposite thereto an abutment surface configured to abut against a corresponding surface of the power skiving tool, wherein the abutment surface extends substantially perpendicularly to the body axis and to the first plane, wherein the cutting end portion is provided with a first cutting edge and a second cutting edge, the first cutting edge and the second cutting edge being directed in a same cutting direction, wherein the first cutting edge extends along an edge portion of the upper surface and the second cutting edge extends in a second plane, the second plane being substantially parallel with the first plane and extending between the upper surface and the first plane, and as seen along a normal to the first plane at least a portion of the second cutting edge extends from the insert body beyond the first cutting edge.
