  • Patent number: 7976694
    Abstract: 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.

  • Publication number: 20110038396
    Abstract: A temperature detecting device includes a current source, a plurality of resistors, a binary counter, a multiplexer, a comparator and a control logic. The current source provides a PTAT current. The resistors provide m voltage signals with ascending or descending voltages. The binary counter generates a binary select signal having (n+1) bits. The m voltage signals are selectively outputted from the multiplexer as a multiplexer output signal according to the binary select signal, wherein 2n<m<2n+1. The comparator is used for comparing the multiplexer output signal with a reference voltage, thereby generating a comparing signal. The control logic is for issuing the start signal. If the comparing signal has a level change, the control logic controls the binary counter to record the binary select signal as a binary temperature signal. The reference voltage does not vary with temperature.
