Patent ID: 8540462

Claim:
A shim plate for mounting in a cutting tool for rotary chip removing machining, the shim plate comprising: a body including of a bottom surface, a contact surface, and one or more individual side surfaces extending between the bottom surface and the contact surface, wherein the bottom surface is adapted to adjoin to a seat surface of the cutting tool, wherein the contact surface is adapted to adjoin to a cutting insert, and wherein the bottom surface and contact surface of the shim plate form a wedge-shape in two perpendicular cross-sections, wherein, in a first cross-section traversing the shim plate, a first wedge shape is formed by a first imaginary straight line (a) associated with the bottom surface and extending from a first intersection point (a 1 ) with the one or more individual side surfaces to a second intersection point (a 2 ) with the one or more individual side surfaces, and a second imaginary straight line (b) associated with the contact surface and extending from a third intersection point (b 1 ) with the one or more individual side surfaces to a fourth intersection point (b 2 ) with the one or more individual side surfaces, and the first imaginary straight line (a) and the second imaginary straight line (b) form an angle α with each, wherein, in a second cross-section traversing the shim plate, a second wedge shape is formed by a third imaginary straight line (c) associated with the bottom surface and extending from a first intersection point (c 1 ) with the one or more individual side surfaces to a second intersection point (c 2 ) with the one or more individual side surfaces, and a fourth imaginary straight line (d) associated with the contact surface of and extending from a third intersection point (d 1 ) with the one or more individual side surfaces to a fourth intersection point (d 2 ) with the one or more individual side surfaces, and the third imaginary straight line (c) and the fourth imaginary straight line (d) form an angle β with each other.
