摘要： In an electrochemical machining tool assembly having at least one electrode (26) arranged across a gap (34) from a workpiece (12), the electrode being energized by application of a potential difference ΔV between the electrode and the workpiece, a method of monitoring machining includes exciting at least one ultrasonic sensor (42) to direct an ultrasonic wave toward a surface (102) of the electrode and receiving a reflected ultrasonic wave from the surface of the electrode using the ultrasonic sensor. The reflected ultrasonic wave includes a number of reflected waves from the surface of the electrode and from a surface of the workpiece. The method further includes delaying the excitation of the ultrasonic sensor a dwell time T d after a reduction of the potential difference ΔV across the electrode and the workpiece occurs.

摘要： A preform (10) includes an airfoil stub (14) and a dovetail hub (16). The hub (16) first undergoes electrochemical discharge machining to form a rough dovetail (32). The airfoil stub (14) undergoes electrochemical machining to form an airfoil (18). The rough dovetail (32) then undergoes electrochemical discharge machining to form a rough tang (34). The rough tang (34) is finish machined to form a dovetail (20) extending from the airfoil (18) in a unitary rotor blade (12).
