A method of forming a workpiece having machinability rating not greater than a machinability rating of Inconel 718. The method may include removing material from the workpiece by moving at least one grinding tool relative to the workpiece and may be conducted at a specific grinding energy of not greater than about 7 Hp/inmin (about 19 J/mm) for a material removal rate of at least about 2.5 in/min&#xb7;in (about 25 mmsec/mm).

Method for forming a workpiece

A system for removing material from a workpiece comprising: a mounted-point grinding tool configured to move from a first position to a second position traversing at least a portion of a slot in a workpiece and removing material from a surface of the workpiece; and a first nozzle configured to deliver coolant to the mounted-point grinding tool, wherein the first nozzle is configured to move with the mounted point grinding tool from the first position to the second position so that the distance between the first nozzle and the mounted-point grinding tool remains substantially unchanged. A second nozzle can be mounted on the opposite side of tool from first nozzle, with the second nozzle also configured to move with the grinding tool so that the distance between the first nozzle and the mounted-point grinding tool remains substantially unchanged during grinding.

Coolant delivery system for grinding applications

In various embodiments, a coolant delivery apparatus is presented. Namely, a coolant delivery apparatus comprises a plurality of internal channels configured to provide coolant to the work face of a grinding wheel.

Apparatuses methods for coolant delivery

An abrasive tool includes a bonded abrasive body having abrasive grains contained within a bonding material, wherein the bonded abrasive body comprises a complex shape having a form depth (FD) of at least about 0.3. The form depth is described by the equation [(Rl&#x2212;Rs)/Rl], wherein Rs is a smallest radius (Rs) at a point along the longitudinal axis of the bonded abrasive body and Rl is a largest radius (Rl) at a point along the longitudinal axis of the bonded abrasive body. The abrasive tool can be used to finish complex shapes in workpieces.
