Abstract
A tool including a working portion with a working member, a side surface and an end surface. The working portion includes a passage passing through the side surface and the end surface. At least one seal is adapted to restrict fluid flow through the side surface and the end surface and at least partially defines a pressure chamber. The working member is adapted to be selectively pivotally positioned by selectively pressurizing the pressure chamber. The tool similarly enables unique methods of working workpieces.
Claims29
A method of removing material from a workpiece comprising the steps of:
- a) providing a tool extending along an axis, the tool including a cantilevered working portion with a working member;
- b) pivotally positioning the working member with respect to the tool axis to a plurality of alternative use positions by providing the tool with fluid at predetermined pressures to bend the cantilevered working portion to control the pivotal position of the working member with respect to the tool axis;
- and
- c) effectuating relative contacting movement between the tool and the workpiece in the alternative use positions of the working member to remove material from the workpiece at different distances from the tool axis by contacting the working member and the workpiece at the alternative use positions.
