摘要： A controller for a wire electric discharge machine which can achieve stable machining with high surface accuracy without requiring adjustment of a gain or the like in wire-electrode feed control. A discharge gap detection unit detects a voltage between a wire electrode and a workpiece. An amount-of-machining-per-unit-distance change detection unit obtains an average machining voltage, and a voltage drop EX that is a difference between the obtained average machining voltage and a no-load voltage. A comparative determination unit obtains a ratio ES/EX between a reference voltage drop ES stored in a reference-amount-of-machining-per-unit-distance relative value storage unit and the drop voltage EX. A feed pulse arithmetic unit obtains a feed speed that makes the amount of machining per unit time constant, on the basis of the ratio ES/EX and a predetermined feed speed, and distributes feed pulses to motors to thereby move the wire electrode relatively to the workpiece. Since the amount of machining per unit time is kept constant, the surface accuracy in finishing is high and stable machining can be performed.

摘要： A discharge pulse number generated between a wire electrode and a workpiece is counted every predetermined time. A ratio Px/Ps of this counted value Px to the reference pulse number Ps will be determined to control an amount of coolant in response to this ratio Px/Ps. Also, in response to this ratio Px/Ps, an amount of movement within predetermined time is controlled. Further, through the ratio Px/Ps and the like, quiescent time to be controlled by the detection voltage generator is controlled. Thereby, surplus supply of energy is prevented, the machining speed and machining precision is improved and any disconnection of the wire electrode is avoided.

摘要： A controller of a wire electric discharge machine monitoring a change in thickness of a workpiece and a current density in real time, promoting a machining speed by preventing occurrence of disconnection of a wire electrode even when the change in the thickness is caused in the workpiece and improving a dispersion in a machining enlargement amount. A machining distance calculating device outputs a signal at each progress of machining by a predetermined distance &Dgr;x. A main pulse number storing device counts a main pulse number for discharge machining outputted from a main pulse generator during a time period of the signal. A thickness calculating device calculates the thickness from a reference main pulse number in machining a reference thickness, the main pulse number stored to the main pulse number storing device and the reference thickness at each reception of the signal. The calculated thickness, further, a machining current, the machining speed and a machining current density are displayed. A discharge pause time control device changes a pause time period of voltage applied to the wire electrode and the workpiece in accordance with a thickness change rate and adjusts the machining current density such that no change is caused before and after the change in the thickness.

摘要： A CPU 290 of a recording/reproducing device 200 make a recording section 251 record contents reserved by a user for video recording in an HDD 270, and sets remaining time until the contents is automatically deleted. The CPU 290 determines, when a period T is over, whether access to the contents has been carried out or not, and adds additional time D to the remaining time when the CPU 290 determines that the access has been made, and subtracts the period T from the remaining time when the CPU 290 determines that the access has not been made. The CPU 290 executes the afore-mentioned processing once in each period T, and automatically deletes the contents from the HDD 270 when the CPU 290 recognizes that the remaining time is zero or below.
