Abstract: An abrasive jet apparatus configured to machine features into an inner diameter of bored structures. In the abrasive jet apparatus, an abrasive mixture of pressurized liquid and abrasive particles is propelled as an abrasive jet in a direction other than the direction in which the abrasive jet apparatus extends. The abrasive jet apparatus may be implemented in an automated boring system and boring method for machining rifling grooves and other features into bored structures. The boring system and boring method use an iterative process of mapping a target surface of the bored structure and adjusting parameters of the boring system in between successive passes of the abrasive jet on the target surface.

Abstract: Systems and methods to generate beneficial residual stresses in a material, clean, strip coatings from, or roughen surfaces by generating cavitation shock waves without damaging the surface of the material. Shock waves emanate through the target material from collapsing cavitation voids in and around a liquid jet to generate residual stresses without impinging the jet against the material, or by impinging the material at shallow angles, and without significantly damaging or deforming the surface of the target material.

Abstract: Systems and methods for generating beneficial residual stresses in a target material by generating cavitation shock waves through the use of a cavitation intensification conditioner. Shock waves emanate through the target material from collapsing cavitation voids in a liquid jet to generate residual stresses without significantly deforming the surface of the target material. A high pressure liquid is accelerated through a submerged peening nozzle to generate a high-speed liquid cavitating jet that is further intensified and controlled by use of the cavitation intensification conditioner.

Abstract: A method and apparatus for milling a desired pocket in a solid workpiece uses an abrasive fluid-jet by moving and suitably orienting the abrasive fluid-jet relative to the workpiece. The method includes defining a path of the abrasive fluid-jet necessary to mill a desired pocket in the solid workpiece. The path is defined by a number of parameters. The parameters include a translation velocity, a fluid pressure, and an abrasive fluid-jet position and orientation relative to the workpiece. Generating a command set is according to the defined path and is configured to drive a computer numerical control manipulator system.
