摘要： An apparatus and method for hybrid machining a workpiece is disclosed. The workpiece is powered as an anode, a cutter is powered as a cathode and a cutting fluid or coolant is circulated therebetween. The cutter is made of a conductive material and a non-conductive abrasive material. The hybrid machine performs a roughing pass machining operation in which material is removed from the workpiece at a relatively high rate using a high-speed electro-erosion (HSEE) process. Then, the hybrid machine performs a finish pass machining operation in which material is removed from the workpiece using precision electro-grinding (PEG) process at a different differential electrical potential and/or flushing rate than the roughing pass machining operation to provide a smooth finish without thermal effects on the workpiece.

摘要： A method for surface roughening a metal work piece includes disposing a region of the workpiece to be roughened proximate to a counter electrode. The region of the workpiece to be roughened and the counter electrode are subsequently disposed together in an electrolyte. An electric potential with current flow is applied between the work piece and the counter electrode to roughen the metal surface to a desired roughness.

摘要： An apparatus and method for hybrid machining a workpiece is disclosed. The apparatus includes a mandrel for supporting the workpiece adjacent a cutter mounted on an arbor. A workpiece is powered as an anode and the cutter is powered as a cathode, and a cutting fluid or coolant is circulated therebetween. The cutter is made of a conductive material and a non-conductive abrasive material to maximize the amount of material removed from the workpiece. The coolant includes one or more additives to enhance the electrical discharge between the cutter and the workpiece. The cutter is moved relative to the workpiece to remove material from the workpiece at a predetermined depth of cut using an enhanced high-speed electro-erosion (HSEE) process in which both HSEE and abrasive machining processes are used. The workpiece may then be finish machined to a final shape of the titanium article, such as a dovetail of a turbine blade.

摘要： An electrochemical machining tool assembly includes first and second tools that are spaced apart from one another so that a workpiece can be located therebetween. The assembly also includes a first ultrasonic transducer mounted in the first tool and a second ultrasonic transducer mounted in the second tool. The electrochemical machining process is monitored by generating ultrasonic waves with the first and second ultrasonic transducers, and then detecting the arrival times, at the first and second ultrasonic transducers, of certain reflections of the ultrasonic waves. The detected arrival times are then used to calculate parameters such as the gap sizes between the first and second tools and a workpiece situated therebetween and the thickness of the workpiece.

摘要： A method for monitoring machining in an electroerosion assembly having a power supply and an electrode arranged across a gap from a workpiece, includes measuring a voltage at a point in a voltage waveform after a time delay td of one half of a pulse width of the voltage waveform. The measurements are repeated for multiple pulses of the voltage waveform to obtain multiple voltages, each of the voltages corresponding to a point in respective pulses. The voltages are averaged to obtain an average voltage, which is compared with at least one threshold voltage, to determine whether the machining is in control. A control signal is generated if the comparison indicates that the process is not in control, the control signal being configured to regulate an operating parameter of the power supply, and the control signal is supplied to the power supply, if generated.
