Abstract
A cutting tool includes a pocket with a top wall, a bottom wall, a side wall and a rear wall. The cutting tool has a wedge clamping system that includes an insert cartridge and a clamp wedge. The insert cartridge includes a recess that interacts with a protrusion on the clamp wedge in such a way that the clamp wedge exerts a force vector in an axial direction when the clamp wedge is threaded into the pocket, thereby reducing deflection of an adjacent pocket of the cutting tool when the cutting tool is placed in a locked condition.
Claims17
A cutting tool comprising:
- a pocket including a top wall, a bottom wall, a side wall and a rear wall;
- and
- a wedge clamping system comprising an insert cartridge and a clamp wedge, the insert cartridge including a recess for interacting with a protrusion on the clamp wedge in such a way that the clamp wedge exerts a force vector in an axial direction when the clamp wedge is threaded into the pocket, thereby reducing deflection of an adjacent pocket of the cutting tool when the cutting tool is placed in a locked condition.
The cutting tool according to claim 7, wherein the protrusion is formed on the bottom wall of the clamp wedge, the protrusion having a top wall with a first portion and a second portion.
A cutting tool comprising:
- a pocket including a top wall, a bottom wall, a side wall and a rear wall;
- an insert cartridge comprising:
- a top wall, a bottom wall opposite the top wall, a pair of opposing side walls extending between the top and bottom walls, and an insert pocket formed in the top wall of the insert cartridge at an intersection between the front wall of the insert cartridge and one of the side walls of the insert cartridge for receiving a cutting insert;
- and
- a clamp wedge comprising:
- a top wall, a bottom wall opposite the top wall, a front wall, a rear wall opposite the front wall, and a pair of opposing side walls extending between the top and bottom walls,
- wherein the insert cartridge includes a recess that interacts with a protrusion on the clamp wedge in such a way that the clamp wedge exerts a force vector in an axial direction when the clamp wedge is threaded into the pocket, thereby reducing deflection of an adjacent pocket of the cutting tool when the cutting tool is placed in a locked condition.
