摘要： In a wire electric discharge machine of the present invention, a control variable detection apparatus is an inter-pole voltage detection apparatus and detects an average inter-pole voltage as a control variable correlating with an inter-pole distance. The wire electric discharge machine comprises a machining feed speed calculation apparatus determining a machining feed speed on the basis of a deviation between target voltage set by a target value setting apparatus 7 and the average inter-pole voltage so as to eliminate the deviation. The wire electric discharge machine further comprises a feed speed distribution apparatus and a relative movement apparatus. The inter-pole distance can be kept constant by the relative movement of a wire electrode and a workpiece made on the basis of a command of thus determined machining feed speed.

摘要： The invention relates to electrochemical machining of current-conducting materials and can be used in the production of punches, pressing molds and other complex-shaped components at the finishing stage. The method comprises supplying square microsecond current pulses synchronized with the moment of maximum convergence of an electrode instrument and an electrode blank for machining within the following parameter range: pulse length t = 10...500 µs, length of the leading and trailing pulse edges τ f = 0,5...5,0 µs, voltage amplitude U a =10-100 V, amplitude density of the current j = 100...10000 A/cm 2 . The process is carried out with the amplitude and pulse length being adjusted in such a manner that the trailing edge of each pulse corresponds to the moment of the greatest electro-conductivity across an inter-electrode gap. The power source is in the form of current generators connected in parallel, in which each generator is connected to a load via a current switch so as to short out the current generator when the current of the generator is not yet at the specified value or when there needs to be a pause between the pulses and switching of the current to pick up and carry the load, in order to form a pulse of the specified length on the load. The normally closed contact of the current switch is connected to a common point while the normally opened contact is connected to the current generator via a diode. The invention makes it possible to increase the efficiency of the electrochemical machining of current-conducting materials and to provide a high-quality surface by optimizing the current pulse parameters and the use of a reliable power source with a common control system.

摘要： An electrical discharge machining in which the machining conditions are automatically updated in such a way that the discharging state matches the target values. Initial machining condition P1, a target electrical discharge state (normal discharge rate, for example) P2, and a constant P3 for calculating a new machining condition are determined. The initial machining conditions P1 are stored in a register D which stores execution machining conditions. The machining starts on the conditions thus stored (S3). The error (E) is obtained between the detection data P4 which represent the discharging state, and the target discharge state (S7). The new machining condition (A) is obtained by adding the product of the error (E) multiplied by the constant PC (= C) to the current machining condition (A) (S8). Thereafter, these steps are repeated and the machining condition is updated so that the discharging state matches the target discharge state. The target discharge state is obtained by the test machining.

摘要： A system for controlling the retraction of an electrode of an electric discharge machine makes is possible to quickly separate and remove the electrode from a workpiece. The retraction speed and forward speed of an electrode (EP) which moves relative to a workpiece (WK) are set to a speed which is obtained by multiplying by a predetermined magnifying power a speed which is determined by a gap-detection voltage in accordance with the size of the gap between the workpiece (WK) and the electrode (EP). The set speed is constantly maintained at a value determined on the basis of the minimum detection voltage during electrode retraction and advance operations. This is designed to improve the machining efficiency by increasing the retraction speed and the forward speed of the electrode (EP).

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 t d 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.
