摘要： An machining method and apparatus whereby the EDM efficiency is markedly enhanced by replenishing the liquid machining medium in the machining gap at an amount of 400 to 3000 cc per unit weight by gram of the stock removal from the workpiece. The machining liquid is supplied into the gap under an elevated pressure of at least 10 kg/cm.sup.2, preferably between 30 and 100 kg/cm.sup.2. The rate of flow of the liquid medium to the gap is controlled in conjunction with and/or in response to at least one of the preset or variable parameters of the electrical discharges and/or as a function of other machining parameters such as the depth of the machining cavity so as to maintain the indicated amount of liquid replenishment.

摘要： An electrical discharge machine is disclosed having a concentration detection function for a rust inhibitor containing an organic compound uses coloring of a metal complex produced through the reaction of the rust inhibitor with a color reagent to enable a detector to detect the change of characteristics involved in the change of the color of the metal complex. A predetermined amount of working fluid is sampled in a sampling cell at regular time intervals, a predetermined amount of color reagent is added to the working fluid, and the change of the color of the working fluid is detected by the detector.

摘要： A method for the determination of lifetime of a filter of an electric discharge machine the electrical discharge machine in consideration of a maximum allowable filter pressure, wherein the time measuring unit counts the machining time ts during which an electric discharge machining process is running, a filter pressure sensor measures the filter pressure p(k), preferably with a predetermined sampling interval, the pressure measurement p(k) and the respective sampling time t(k) are stored, and the sampled measurements p(k) and the respective sampling times t(k) are used to determine the parameters of an exponential function which best fits to the plurality of sampled measurements regression analysis. The determined parameters include the filter lifetime tf, which serves to determine the residual time to the filter replacement tr and/or the calendar deadline of filter expiration.
