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.

Abstract: A metal cutting system with a tool holder, a shim, an insert with a top depression, a top piece and a clamp. A rake face cooling channel for fluid delivery is formed between the top piece and the depression in the insert. A primary discharge slot at the end of the rake face cooling channel delivers fluid from below the cutting edge of the insert. A second cooling channel for delivery of fluid to the flank face is formed between the insert and the shim or is formed between the shim and the tool holder with a portion of the cooling channel passing through the shim.

Abstract: A toolholder with a controllable critical angle, such as a lead, trailing, rake or clearance angles, includes a tool spindle for retaining the toolholder in a tool rest of a machine tool. The machine tool includes at least one linear axis, for example, three mutually perpendicular axes, a rotary axis and a rotation axis. The rotary axis and/or rotation axis is controllable to move to a specified position in synchronization with a movement of one of the linear axes. An adaptor supports a cutting tool that is retained in the adaptor by a clamp. The cutting tool defines a critical angle, such as a lead angle, a trailing angle, a rake angle and a flank clearance angle, wherein the critical angle is corrected as a vector of movement of at least one of the linear axis is changed. In addition, the cutting tool can be positioned on opposite side of a centerline of rotation of the workpiece to effectively double the life of the cutting tool. A method of controlling a toolholder is also disclosed.

Abstract: A cutting insert for use in chipforming and material removal from a workpiece wherein coolant is supplied to the cutting insert from a coolant source. The cutting insert includes at least one discrete cutting location and at least one distinct internal channel that corresponds to the cutting location. The internal channel has an inlet to receive coolant and an outlet to exit coolant. The outlet is proximate to the cutting location, and the inlet is radial inward of the outlet.
