摘要： An electric discharge machining apparatus has a pair of carbide formation detectors for minimizing carbide formation and for preventing abnormal discharges from occurring across the machining gap. If the discharge voltage is below a lower reference voltage for a predetermined period of time and for a predetermined number of ON/OFF cycles, then the first detector compares the discharge voltage with a higher voltage level. When the discharge voltage is greater than the higher level for a predetermined period of time and for a predetermined number of ON/OFF cycles, the first carbide detector generates an ARC STOP signal for halting the machining operation. A second carbide formation detector will generate an ARC STOP signal for halting the machining operation when the discharge waiting time is less than a predetermined period of time for a predetermined number of cycles. By having the two carbide formation detectors, abnormal discharges such as concentrated arc discharges and continuous arcing discharges are prevented. Also, machining efficiency is improved since operator supervision for detecting carbide formation is no longer necessary.

摘要： A power supply for an electroerosion machine having a switching element which controls the machining current in the gap. The value of the current is compared with a predetermined voltage and the signal generated based on this comparation is provided to a logic gate, advantageously an "AND" gate, whose output signal is applied to the control electrode of the switching element. The power supply surpresses any arcing tendency during gap short circuit conditions and increases the total current through the gap even when gap voltage is low in order to maintain a high machining rate. Electrode consumption is reduced by using a generally step-type current waveform signal. Machining current during the discharge period may be controlled to more closely approximate a square wave so that shifting to a faster machining rate can be easily accomplished by accepting some sacrifice in electrode consuption. Preferably, two or more switching and gating devices are used to permit gap current to flow intermittently during the entire discharge period.

摘要： A method of and apparatus for controlling electric discharge machining in which a machining gap formed between a tool electrode and a workpiece is maintained at an essentially constant size based on a reference servo-feed voltage, and in which a jump action, for moving a tool electrode up and away from a workpiece, and returning it to a position close to the workpiece is controlled. The reference servo-feed voltage and conditions for jump action are optimally set to required values during machining according to the discharge stability. The discharge stability is obtained by comparing the actual values of characteristics required for specifying gap condition, e.g., waiting time for a discharge to occur, the voltage during the waiting time, discharge frequency, to the corresponding theoretical values. The theoretical values are calculated in part according to given machining conditions. Therefore, even when machining conditions change as machining progresses, jump action and servo-feed action are properly controlled.

摘要： A method of and apparatus for supplying power during EDMing in which reverse polarity pulses are used to inhibit electrolytic activity. A main voltage pulse of a certain polarity and an auxiliary voltage pulse, preceding the main voltage pulse of the same or reverse polarity, are applied across a machining gap during the on time of a main gate signal and until a discharge is detected. The ratio of the number of auxiliary voltage pulses of regular polarity to those of reverse polarity is set to a desired value depending upon machining conditions, to thereby obtain a good compromise between the conflicting requirements of achieving a high machining rate, while inhibiting undesirable electrolytic activity.
