Abstract
A rotating cutting tool is selectively biasable in the radial direction based on the angular orientation of the cutting blade, which may be used to create a non-axis symmetric feature in a bore. The radial position of the cutting blade may be controlled by selectively pressurized fluid whose pressure is varied based on the angular orientation of the tool. A plurality of vents may be selectively covered and uncovered to vent pressurized fluid to vary the pressure thereof.
Claims27
A tool for cutting material from a workpiece comprising:
- at least one blade member including a blade configured to cut material from the workpiece, said at least one blade member being selectively biasable to at least one of a plurality of alternative use positions;
- and a selective bias device configured to selectively bias said at least one blade member to at least one of a plurality of alternative use positions based on angular orientation of said at least one blade member, wherein the selective bias device comprises a selectively pressurized fluid, wherein said tool includes a conduit configured for said pressurized fluid, said conduit including one or more vents configured to allow a flow of said pressurized fluid to exit said conduit, and comprising means for selectively covering or uncovering said one or more vents as a function of the angular orientation of said tool.
A tool for cutting material from a workpiece, comprising at least one blade member including a blade configured to cut material from the workpiece, said at least one blade member being selectively biasable by a selectively pressurized fluid to at least one of a plurality of alternative use positions based on angular orientation of said at least one blade member, wherein said tool includes a conduit configured for said pressurized fluid, said conduit including one or more vents configured to allow a flow of said pressurized fluid to exit said conduit, and comprising means for selectively covering or uncovering said one or more vents as a function of the annular orientation of said tool.
A method of using a tool to cut material from a workpiece, the method comprising the steps of:
- a. providing a tool comprising at least said blade member being selectively biasable to at least one of a plurality of alternative use positions;
- b. rotating the blade member and the workpiece relative to one another so that the blade removes material from the workpiece;
- c. selectively biasing said at least one blade member to at least one of a plurality of alternative use positions based on angular orientation of said at least one blade member relative to said workpiece, further comprising the step of causing pressurized fluid to bear on said at least one blade member in order to selectively bias said at least one blade member, further comprising the step of causing the pressure of said pressurized fluid to vary based on the angular orientation of said at least one blade member relative to said workpiece, wherein said tool includes a circumferential surface, and wherein the step of varying the pressure comprises the step of selectively covering and uncovering any of a plurality of vents formed in said circumferential surface.
