Abstract
A machining tool is provided having an insert that includes one or more interface surfaces configured to interact with a workpiece. The machining tool also has one or more distribution passages located within the insert. The one or more distribution passages are situated and sized to direct a fluid to the one or more interface surfaces while maintaining the fluid above a pressure at which the fluid exists in a supercritical state.
Claims20
A method for machining a workpiece, comprising:
- manipulating a fluid to exist in a supercritical state;
- directing the fluid through an insert of a machining tool while maintaining the fluid in the supercritical state;
- using the insert to remove a portion of the workpiece;
- and
- directing the fluid to an interface surface of the insert that is interacting with the workpiece while maintaining the fluid in the supercritical state.

A method for machining a workpiece, comprising:
- pressurizing a fluid to a desired pressure such that the fluid exists in a supercritical state as a gas;
- directing the fluid through a machining tool while maintaining the fluid in the supercritical state;
- using the machining tool to remove a portion of the workpiece;
- and
- directing the fluid to an interface surface of the machine tool that is interacting with the workpiece while maintaining the fluid in the supercritical state.

A method for machining a workpiece, comprising:
- manipulating a fluid to exist in a supercritical state, wherein a temperature of the fluid is above a critical temperature and a pressure of the fluid is above a critical pressure;
- directing the fluid through a machining tool;
- using the machining tool to remove a portion of the workpiece;
- and
- directing the fluid to an interface surface of the machine tool that is interacting with the workpiece while maintaining the fluid in the supercritical state.
