    • In an electric discharge machining power source having a capacitor discharge circuit with a switching element, charging of a capacitor is stopped through an OR gate (G1), a NOR gate (G2) and a preamplifier (A1) in response to an output from a charge voltage detecting circuit (1) for generating the output when a charge voltage across the capacitor exceeds a reference voltage. At the same time, the switching element is turned on through a preamplifier (A2). The switching element is kept on through the OR gate (G1) and the preamplifier (A2) until a discharge current detecting circuit (4) detects the discharge current and stops generating the output. When the capacitor is completely discharged, the switching element is turned off. When a predetermined period of time has elapsed under the control of a monostable multivibrator (3), the capacitor is recharged.

    • A wire EDM circuit uses a references voltage connected to a short circuit detector for comparing an average voltage with a reference voltage. Whenever the average voltage is below the reference voltage the numeric controller causes the pulse oscillator to stop generating a pulse stream. In order to also finish machine the workpiece a reference voltage switching circuit is used to decrease the reference voltage. There is also provided an internal signal blocking circuit to block an interval signal oscillator to stop generation of the pulse stream when the wire electrode is temporarily in contact with the workpiece or when phenomena similar to a short circuit occurs.

    • An electrical discharge machining method for automatically updating machining conditions so that the discharge state agrees with a target value and an electrical discharge machining apparatus for carrying out the method. Initial machining conditions, a target discharge state (e.g., normal discharge rate) and a constant for computing new machining conditions are set. A register for storing actual machining conditions is loaded with the initial machining conditions, and machining operation is started under these machining conditions. The deviation between detected data indicative of the discharge state and the target discharge state is obtained. The new machining conditions are obtained by adding the product of the deviation and the constant to the current machining conditions. These processings are repeated in succession, and the machining conditions are updated so that the discharge state agrees with the target discharge state. The target discharge state is obtained by test machining.

    • A method of displaying an operation history of a machine, which permits quick and proper investigation of the causes of troubles and trouble-shooting therefor. A processor of a numerical control device mounted on the machine writes a block number in a corresponding address region of a memory every time one block of a machining program is read out, and executes the block after an index indicating the address region to be stored with the next block number is determined (S1 to S4, S6). If the determined index exceeds a value indicating the last address region, the index is reset to a value indicating the first address region (S5). During the execution of each block, the processor successively determines, with respect to all the circuit sections of an input/output circuit, the presence/absence of signal transfer through each circuit section (S12), and causes a memory address region corresponding to the block to successively store codes individually indicating those circuit sections concerned in the signal transfer (S13), so that block numbers indicating up-to-date blocks and codes indicating the circuit sections concerned in the signal transfer during the execution of the blocks are continually held in their associated memory address regions, whereby the operation history of the machine is recorded. In response to a display command, the block numbers and codes constituting the operation history are successively displayed on a display screen according to precedence (S21 to S26).
