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： The disclosed circuit is for controlling step motors of the type which have access only to a common winding neutral point or to partial neutral points. A switching transistor switches a low-loss circuit into the motor drive circuit for free running of the motor. A common circuit common to all the windings is switched in for rapid switching off of the current in the windings and for recovery of the energy stored in the inductors of the circuits.

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.

摘要： To permit machining of workpieces on spark erosion cutting equipment with large angles of inclination, the guidance heads which guide the wire electrode in the cutting zone with respect to the workpiece are pivotably arranged and controlled, by being mounted on individual gimbal suspensions so that it is possible to provide for a controllable slope angle up to large amounts. Individual drive motors control movement about the respective gimbal axes.

摘要： Erosive working machine for cutting prepared closed inner shapes (15) and closed outer shapes (16) of a workpiece (12) fixed by a workpiece holder by means of a filamentary or strip electrode (14) arranged on guidance means (13, 18). At least one guidance means (13, 18) is arranged on a motor-rotatable rotating mechanism (20) in such a way that the center line (23) of rotating mechanism (20) at at least one geometrical locus coincides with the center of the cross-section of electrode (14). Thus, during the erosion process, a collision between the guidance means (13, 18) and the closed inner shape (15) or closed outer shape (16) or a tool holder (11) is avoided.

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.
