Abstract
A slotting cutter includes a disc-like cutter body rotatable in a predetermined direction on a central axis perpendicular to a plane of the cutter body. A plurality of cutting insert receiving pockets and a corresponding number of wedge receiving pockets are formed about a perimeter of the body. A cutting insert is replaceably mounted in each insert receiving pocket of the cutter body, and a clamping wedge is replaceably mounted in each wedge receiving pocket of the cutter body. A cantilevered member is disposed between each insert receiving pocket and a respective wedge receiving pocket to securely hold the cutting insert in the cutter body.
Claims19
A slotting cutter, comprising:
- a disc-like cutter body rotatable in a predetermined direction on a central axis perpendicular to a plane of the cutter body;
- a plurality of cutting insert receiving pockets formed about a perimeter of the body;
- a plurality of wedge receiving pockets formed about the perimeter of the cutter body;
- a cutting insert replaceably mounted in each insert receiving pocket of the cutter body;
- a clamping wedge replaceably mounted in each wedge receiving pocket of the cutter body;
- a cantilevered member disposed between each insert receiving pocket and a respective wedge receiving pocket, the cantilevered member including an undercut feature and a pair of slots extending radially inward with respect to the undercut feature toward the central axis of the cutter body, each slot having a width and a length,
- wherein a thickness, t3, of the cantilevered member along the entire length of the pairs of slots is greater than a thickness, t2, of the cantilevered member at the undercut feature.

A slotting cutter, comprising:
- a disc-like cutter body rotatable in a predetermined direction on a central axis perpendicular to a plane of the cutter body;
- a plurality of cutting insert receiving pockets formed about a perimeter of the body, each insert receiving pocket defined by a rearward wall, a bottom wall and a radius at the intersection between the rearward wall and the bottom wall;
- a plurality of wedge receiving pockets formed about the perimeter of the cutter body, each the wedge receiving pocket defined by a rearward wall and a top wall for engaging the clamping wedge;
- a cutting insert replaceably mounted in each insert receiving pocket of the cutter body, the cutting insert including a top surface and a bottom surface;
- a clamping wedge replaceably mounted in each wedge receiving pocket of the cutter body;
- a cantilevered member disposed between each insert receiving pocket and a respective wedge receiving pocket, the cantilevered member including an undercut feature and a pair of slots extending radially inward with respect to the undercut feature toward the central axis of the cutter body, the cantilevered member including a top surface for engaging the bottom surface of the clamping wedge and a bottom surface for engaging the top surface of the cutting insert,
- wherein the top surface of the cantilevered member is complementary in shape to the bottom surface of the clamping wedge, and
- wherein the bottom surface of the cantilevered member is complementary in shape to the top surface of the cutting insert, and
- wherein a thickness, t1, between the top surface and the bottom surface of the cantilevered member is greater than a thickness, t2, of the cantilevered member at the undercut feature, and
- wherein a thickness, t3, of the cantilevered member along the pairs of slots is greater than or equal to the thickness, t1, of the cantilevered member between the top surface and the bottom surface of the cantilevered member.
