Abstract
The present invention relates to cutting tools with cutting inserts and, more particularly, to cutting tools with cutting inserts that have mounting recesses. The cutting insert includes a body having a mounting hole having an axis extending therethrough, and a surface portion in the mounting hole. The surface portion is substantially circular when viewed in a direction of the axis and is non-parallel to the axis and including at least two contact points disposed at a lesser distance from the axis than a region between the at least two contact points. A cutting tool is also disclosed.
Claims18
A cutting insert, comprising:
- a body having a mounting hole having an axis extending therethrough;
- and
- a surface portion in the mounting hole, wherein the surface portion is substantially entirely circular when viewed in a direction of the axis and the substantially entirely circular surface portion is also substantially entirely non-parallel to the axis and comprises at least two contact points disposed at a lesser distance from the axis than a region between the at least two contact points, wherein the at least two contact points comprise protrusions from the surface portion.
A cutting insert, comprising:
- a body having a mounting hole having an axis extending therethrough;
- and
- a surface portion in the mounting hole, wherein the surface portion is substantially entirely circular when viewed in a direction of the axis and the substantially entirely circular surface portion is also substantially entirely non-parallel to the axis and comprises at least two contact points disposed at a lesser distance from the axis than a region between the at least two contact points, wherein the region between the at least two contact points comprises a recess in the surface portion, the recess extending for less than a length of the surface portion.
A cutting tool, comprising:
- a cutting insert comprising an insert body having a mounting hole having an axis extending therethrough, and a surface portion in the mounting hole,
- a toolholder;
- and
- a clamp for securing the cutting insert relative to the toolholder,
- wherein the surface portion is substantially entirely circular when viewed in a direction of the axis and the substantially entirely circular surface portion is also substantially entirely non-parallel to the axis and comprises at least two contact points disposed at a lesser distance from the axis than a region between the at least two contact points and the clamp has a portion disposed in the mounting hole for contacting the at least two contact points and securing the cutting insert relative to the toolholder, wherein the at least two contact points comprise protrusions from the surface portion.
A cutting tool, comprising:
- a cutting insert comprising an insert body having a mounting hole having an axis extending therethrough, and a surface portion in the mounting hole,
- a toolholder;
- and
- a clamp for securing the cutting insert relative to the toolholder,
- wherein the surface portion is substantially entirely circular when viewed in a direction of the axis and the substantially entirely circular surface portion is also substantially entirely non-parallel to the axis and comprises at least two contact points disposed at a lesser distance from the axis than a region between the at least two contact points and the clamp has a portion disposed in the mounting hole for contacting the at least two contact points and securing the cutting insert relative to the toolholder, wherein the region between the at least two contact points comprises a recess in the surface portion, the recess extending for less than a length of the surface portion.
