Abstract
A cutting insert-shim assembly that has a cutting insert with a bottom surface and a plurality of interior coolant passages wherein each interior coolant passage has a coolant inlet in the bottom surface of the cutting insert. The shim has a first side surface and a second side surface and contains a cavity, which communicates with the coolant conduit. The cavity defines a first opening in the first side surface and a second opening in the second side surface. When the shim is in a first condition, the first side surface contacts the bottom surface of the cutting insert and the first opening provides a first level of coolant communication to the interior coolant passages in the cutting insert. When the shim is in a second condition, the second side surface contacts the bottom surface of the cutting insert and the second opening provides a second level of coolant communication to the interior coolant passages in the cutting insert.
