More Information
Summary:A method is provided for machining a workpiece (24). During this machining method, an aperture (22) is formed in the workpiece (24) using a machining system (20). The machining system (20) includes an ultrasonic machining device (28), a slurry delivery device (27) and a controller (78). The forming of the aperture (22) includes delivering a slurry to an interface (34) between the ultrasonic machining device (28) and the workpiece (24) using the slurry delivery device (27), and transmitting ultrasonic vibrations into the slurry using the ultrasonic machining device (28). A feedback parameter is monitored during the forming of the aperture (22) using the controller (78). A slurry delivery parameter for the slurry delivery device (27) is adjusted during the forming of the aperture (22) based on the feedback parameter using the controller (78).
