摘要： A method and device for electrical discharge machining (EDM) a workpiece by means of a train of machining pulses. During the machining time the machining pulses are applied to the working gap between workpiece and electrode. An open voltage is first applied, and it is increased to a second open voltage level if a discharge does not occur within a waiting time d0, and further increased to a third open voltage level if a discharge does not occur within a second waiting time d1.
An average product of the actual open voltages times the partial ignition delays is computed and subtracted from the product of a reference open voltage times the total ignition delay, and the servo setpoint value is adjusted accordingly. The actual axes positions are sampled in real time and the discharge electrical parameters are adjusted accordingly. The discharge electrical parameters can be adjusted according to the duration of d0 and d1.-

摘要： A crash prevention device for a machine tool for preventing the collision of a moving part of the machine tool with other machine tool parts or with a workpiece in a working area of the machine tool includes an isolation mechanism that electrically isolates the moving part from the other machine tool parts or the workpiece. The device includes a detection system with a high voltage generator having a first positive connector electrically connected to the moving part and a negative connector electrically connected to the workpiece or to the other machine tool parts. The high voltage generator generates DC, AC, or pulsating voltage. The detection system includes a discharge detection device that detects an electrical discharge between the moving part and the workpiece or between the moving part and the other machine tool parts, then sends a signal to stop or adapt further relative movement of the moving part.

摘要： An expansion of known serial data links, for example ETHERNET, published in IEEE802.3, for directly transmitting random events without having to carry out synchronization with a clock signal or having to wait for a cyclical transmission time. Two different, random events are represented using two differently coded individual pulses and are transmitted in an event-controlled manner. A jitter-free latency of 45 ns between the event and its reception is possible over a line length of 8 m, for example. The expansion is particularly suitable for the short, digital data links between a node and a plurality of modules, as are required in modern electrical discharge machines, machine tools and similar electronic systems.

摘要： The methods and devices enable a reliable and rapid automatic threading process on spark-erosive wire-cutting machines with closed round guides without complicated entry of parameters. A heat-output control device with an optimized output characteristic curve is supplied from a DC voltage source of the erosion generator. Through an at least partial feedback loop of heating current and source voltage, the characteristic curve is modified in such a way that different wire types or different annealing lengths for the wire provide optimal results for stretching, straightening and separating the wire electrode without controlled intervention. With adaptive control it is possible to thread future wire types automatically without reprogramming.

摘要： Spark-erosion machining method and machine implementing a machining gap, a process regulator, a numerical control system, a Nominal Trajectory. The latter describes the movement of the tool electrode relative to the part as it ought to proceed if no disturbance were to occur during the machining. Information contained in the Nominal Trajectory is used to define at least two control vectors Vg, Vp which orient, within the coordinate system XYZ, two independent regulation movements. The first, or Gap Vector Vg, defines the direction in which a first regulation movement of the axes of the machine must be performed to maintain the removal of material. The second, or Position Vector Vp, defines the direction in which a second regulation movement of the axes of the machining machine must be performed to correct a tool electrode position error. The respective amplitudes of the regulation movements are calculated in real time by the process regulator.
