摘要： A head assembly for an electro-erosion machine tool comprises, in a housing, a guide for guiding the moving filamentary or strip-form tool electrode and first contact means for supplying erosion energy to the electrode. The scavenging medium is fed into the housing so as to cool the contact means and guide, and leaves it by way of a nozzle through which also the electrode leaves the housing on its way to another head assembly arranged on the opposite side of the location where machining is performed, the scaverging medium being thereby fed to the machining location as an envelope coaxial to the electrode. Second contact means for contacting the workpiece to be machined are fixed to the nozzle and the connections to each contact means are arranged for low inductive energy loss.

摘要： In a spark erosion machine in which the tool electrode comprises a tensioned flexible wire or tape, machining induced force due, for example, to the magnetic and electric fields induced by the sparks, act on the tool electrode and may cause it to vibrate. To reduce the tendency for such vibration, a compensating signal is passed through the tool electrode or applied between the tool electrode and workpiece so as to produce a magnetic or electric field which compensates for the machining induced forces. The compensating signal is preferably adjustable in magnitude and/or frequency (the latter assuming it is an alternating signal) and the output of the generator which produces it is decoupled from the output of the spark pulse generator. The spark pulse generator and the compensating signal generator may be interdependently synchronized by a synchronizing signal lead connected between them.

摘要： A main and an auxiliary energy supply device supply energy to a load normally and during disturbances of the main supply respectively while, for bridging brief disturbances in the load supply, for example naturally brief disturbances or during the short time when a disturbance has begun and the auxiliary supply has not yet come into operation, there is provided an energy store which can receive and store energy from the main supply and make this stored energy quickly available to the load. A control logic system controls the main and auxiliary supply devices and the storage means to ensure substantially constant energy supply to the load. The disturbances in question may comprise voltage rises or reductions and/or waveform distortions for example.

摘要： Electroerosion machining (EDM or ECM) is carried out with a minimum of manual intervention. Under control of recorded data an electronic control system utilizing control logic directs the set-up operations as well as the actual machining process. The operations automatically (i.e., without the necessity of manual intervention) include loading and removal of workpieces and electrode material, trueing up of the workpiece (which may be by providing a transformation of the data rather than by adjusting the position of the workpiece), making starting bores, threading the electrode through a starting bore, applying a low melting alloy or other conducting adhesive to cement a core in the process of being cut out by machining, cutting the electrode after completing a starting bore and joining electrode ends after rethreading in a new starting bore. In threading the electrode it may be pushed simply or with the support of a surrounding jet of pressure medium, or it may be pulled by a grapple member.

摘要： The peak voltage of each discharge pulse is measured and, if the voltage of the pulse exceeds a high threshold value, there is also measured the time between the passing of that value and the moment the pulse voltage thereafter drops below a second lower threshold value. The two measurements are expressed in pulses that are combined, preferably by addition, to provide a regulating value, whose deviation ("error") from a standard value is predicted for a coming period, taking account of recent electrode position change as well as regulating value trend. The sign of the predicted error determines in which direction the electrode drive motor will be energized, but if the predicted error is less than a threshold value no motor energization occurs until the next error prediction. The sense in which the regulation operates is so defined that at a time when the electrodes are not already in relative movement an increase in the regulating value, at least if it persists, causes the electrodes to be moved closer together.
摘要翻译：测量每个放电脉冲的峰值电压，并且如果脉冲的电压超过高阈值，则还测量该值的通过与此后脉冲电压下降到低于第二较低阈值的时刻之间的时间。这两个测量值以组合脉冲的形式表示，优选通过加法来组合，以提供一个调节值，该调节值考虑到最近的电极位置变化以及调节价值趋势。预测误差的符号决定了电极驱动电动机将在哪个方向被激励，但是如果预测误差小于阈值，则直到下一个误差预测才会发生电机通电。调节操作的感觉如此定义，使得在电极尚未相对运动的时候，调节值的增加至少如果持续，则使电极移动得更靠近在一起。

摘要： To provide constant tension on an electro-erosive electrode machining wire, tape or ribbon stretched in a working path between advancing rollers and pulling rollers, a tension loading arrangement, for example weights, springs, or the like, are applied to the wire to maintain the tension thereof at a constant value. The deflection of the wire, due to elongation thereof as a result of heating, differences in manufacturing technologies and the like, is sensed and fed back to the motors driving the advancing and pulling rotors to maintain the tension, as controlled by the motor torques and speeds at a uniform value.

摘要： A pulse generator for metal machining by electric discharges, comprising a primary current circuit for producing and transmitting pulse forms to a pair of electrodes. A voltage and/or current source is arranged in the low-ohm and low-loss primary current circuit, the voltage of which has a value which is only that much greater than the operating voltage of the pulses flowing through the spark gap as is needed to positively overcome the voltage losses occurring in the primary current circuit. A signal generator produces a signal corresponding to the desired current pulse shape or form. A comparator, which has a switch arranged in the primary current circuit for regulating the current flow in such primary current circuit, controls the current flowing through the primary current circuit, as a function of the desired pulse form produced by the signal generator and a magnitude of the current flowing in the primary current circuit which is tapped-off by a measuring feeler. A magnetic energy storage arranged in the primary current circuit and having a switch in parallel to the work gap produces a voltage having a value greater than the voltage of the current and/or voltage source, and the primary current circuit is designed such that there is only present stray capacitance.

摘要： An assembly such as a tool head for a spark erosion profiling machine tool comprises an elongate tool holding member having first and second opposed lengthwise bearing surfaces and third and fourth opposed lengthwise bearing surfaces. By way of example the member can be square, the bearing surfaces then being the four long sides of the member. The member is partly housed in a housing wherein there are mounted bearings which support the member for movement in the direction of its length with respect to the housing. The bearings can comprise discrete circulating roller bearing shoes and they are in abutting contact with the member at five positions in the region of each of two planes spaced apart along the length of the member by a calculated optimum distance. In each plane, two of the abutting contact positions are on the first bearing surface, one is on the second surface, and the other two are on respective ones of the third and fourth surfaces in the region of a plane which is about midway between the first and second surfaces. The housing can be in one piece or it can comprise a part having a base and side walls defining a channel, and a part forming a cover for the mouth of the channel.

摘要： A control system, for a machine tool of the kind in which electrical energy passes across a gap between a tool electrode and a workpiece to erode the workpiece, comprises means for forming signals representative of the rate of erosion of the workpiece and the rate of undesirable erosion or "wear" of the tool electrode, and a computer means which receives the signals and combines them with a signal received from a data input device, which signal represents a desired optimum relationship between the two rates of erosion, and forms an appropriate output signal for controlling the machine tool. The data input device is usable, in rough machining operations where the tool electrode may be relatively cheaper than machine time, to ensure that machining is done in the shortest time by allowing a relatively high rate of tool wear and, in fine machining where the tool electrode is expensive, to ensure minimal tool wear at the cost of machine time.

摘要： Two condition index variables are used for controlling operation in such a manner that one of the variables is kept as close as possible to a minimum value, while the other is held within an assigned range. Both condition index variables depend on the rate of flow of the flushing liquid through the working gap, on the interval between discharges in the gap or on the duty cycle or repetition frequency and amplitude of the discharge pulses. The condition index variable held to a minimum may be the integral of the square of the error signal from the regulating circuit of the electrode advancing drive, the integral of the square of the acceleration of electrode movement or the quotient obtained by dividing the square of the error signal by the square of the gap current. The regulating value to be held within an assigned range is a calculated breakdown potential defined by the relation of the variation of the error signal to the variation of the electrode spacing. The condition index variables are used to control the interval between discharges, the electrode spacing, the flow of flushing liquid, or other variables of the operation. Control of the flow of flushing liquid may be done directly where the liquid is supplied to the gap through holes in the workpiece or indirectly by intermittently backing off the electrodes to a controlled extent.
