摘要： 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.

摘要： A system forms a part in an initial geometry (e.g., a sheet) into a desired geometry. The system includes a robot arm with an end effector, a model and a controller. The model receives an input geometry and an input parameter value indicating an interaction between the part and the end effector. The model determines an output geometry of the part based on the input geometry and the input parameter value. The controller receives the initial and desired geometries; applies the model to the initial geometry and to different input parameter values; based on output geometries of the model, determines a set of parameter values for controlling the robot arm; and controls the robot arm according to the determined set of parameter values to form the part into the desired geometry using the end effector.

摘要： An ultrasonic peening-type integrated machining method for cutting and extrusion includes: applying transverse ultrasonic vibration or a vibration component, which is vertical to a cutting speed direction to a cutting tool on a machine tool; setting a cutting parameter and an ultrasonic vibration parameter such that a dynamic negative clearance angle is generated in a cutting procedure and a flank face of the cutting tool conducts ultrasonic peening extrusion on the surface of the workpiece; setting an extrusion overlap ratio; setting a wear standard of flank faces extruded by the cutting tool; controlling a vibration cutting trajectory phase difference of the cutting tool during two adjacent rotations; and turning on the machine tool in order to ensure that cutting and surface extrusion strengthening of the workpiece are completed in one procedure without separate strengthening procedures. The method conducts extrusion strengthening on the surface of the workpiece while cutting the workpiece.

摘要： A polishing method is described for polishing a machine component comprising at least one airfoil portion comprised of a suction side, a pressure side, a leading edge and a trailing edge. The method provides for arranging the machine component in a container and constraining the machine component to the container. A polishing mixture is added in the container, and the container is caused to vibrate together with the machine component constrained thereto, thereby generating a polishing mixture flow along the airfoil portion until a final arithmetic average roughness is achieved.
