| 英文摘要 | A pulse energy at 100MHz is verified to be able to determine the normal and abnormal discharge during electrical discharge machining (ED-Ming). A band pass filter is designed to detect the energy at this frequency, and can verify which discharge pulses are normal and abnormal, respectively. A field programmable gate array (FPGA) is used to implement the discharge detection circuit, including detection of the time of ignition (T□) and discharge high-energy. Function analysis is used to design the proportional (P) T□ controller to allow the bounded variation of reference input and the feedback signals. Energy of about 100MHz can be maintained within a specified pulse width by regulating the position of the electrode, including a slight regulation and jump motion. The rate of erosion during the roughing and finishing of a die-sinking EDM is confirmed to demonstrate the improvements obtained by the EDMing. |
