Abstract: A method of machining a feature in a workpiece includes orienting a waterjet guided laser device about the workpiece, ejecting a waterjet from a nozzle of the waterjet guided laser device, impinging the waterjet against the workpiece along a tool path causing a corresponding removal of material therefrom, and generating a non-uniform electric field proximate the waterjet to cause a deflection of the waterjet as the waterjet is impinging against the workpiece.

Abstract: An ultrasonic impact grinding assembly includes a base with a mount for connecting a workpiece to the base and a first tool arm. The ultrasonic impact grinding assembly also includes a second tool arm. The first tool arm and the second tool arm each include a base end, a distal end, at least one joint between the base end and the distal end, and at least one actuator configured to move the at least one joint. A first ultrasonic impact grinding tool head is connected to the distal end of the first tool arm. A second ultrasonic impact grinding tool head is connected to the distal end of the second tool arm.

Abstract: A method of machining ceramic matrix composite components includes providing an ultrasonic vibration tool having a tool tip, and exciting the tool by providing a control current, such that the tool tip is repeatedly vibrated towards and away from a ceramic matrix composite workpiece. A slurry feed is supplied including abrasive particles to a surface to be machined by the tool tip. A vibration amplitude of the tool tip is controlled by sensing load on the tool and communicating with a computing device. The computing device controls the vibration amplitude of the tool tip. The computing device is provided with at least one memory programmed with historic data, and is operable to modify the vibration amplitude signal being sent to the tool, and comparing resulting load levels due to the change in vibration amplitude signals, and storing the change in vibration amplitude signals at the memory.

Abstract: A tool for ultrasonic impact grinding apparatus driven to vibrate along a longitudinal axis at an applied operating frequency includes a tool body disposed on the longitudinal axis, a first tip extending from an output end of the tool body, and a second tip extending in parallel to the first tip from the output end of the tool body. The first tip has a first length. The second tip has a second length greater than the first length. A mass of the first and second tip is substantially balanced across the output end of the tool body and with respect to the longitudinal axis.

Abstract: A method of forming a component for a gas turbine engine using ceramic matrix composites (CMCs) is provided. The method includes preforming the aerodynamic component into an initial desired shape using the CMCs, executing partial densification of the CMCs, repeating the preforming operations and the executing of the partial densification until a final desired shape of the aerodynamic component is achieved, machining or cutting the CMCs during one or more of the preforming operations and the executing of the partial densification to remove defects from the CMCs and executing a full densification of the CMCs.

Abstract: A tool for an ultrasonic impact grinding machine driven to vibrate along a longitudinal axis includes a hollow tool body and a hollow tip extending from an end of the hollow tool body. The hollow tip has an outer surface comprising a plurality of grooves. The hollow tool body and the hollow tip are disposed about the longitudinal axis and the hollow tip and hollow tool body are each defined in part by a common bore extending along the longitudinal axis.
