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 method for controlling a wire electrical discharge machining (WEDM) process, in which the wire traveling speed VW is adapted in-process, while cutting. The method for controlling a wire electrical discharge machining (WEDM) process according the invention includes adapting the wire traveling speed in-process, wherein the method comprises the steps of: determining the position of each discharge along the engagement line of a wire and a work piece; determining the size of a crater provoked at the wire by each discharge; creating a real time wire wearing model based on the position of each discharge along the engagement line of the wire and the work piece, and based on the size of the crater occurring at each said determined position of each discharge along the engagement line of a wire and a work piece, and based on the current wire traveling speed; and continuously comparing the wire wearing model with one or more wire wearing limits, and adjusting the wire traveling speed according to the comparison of the actual wire wearing model and the one or more wire wearing limits. The wire electrical discharge machining process is conducted with reduced wire consumption, safely, efficiently and profitably.

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： A high-speed reciprocating wire cutting process in which a wire electrode is transported and precisely guided across a machining area by means of a wire traveling circuit, whereas the cutting process is conducted by repeatedly: running the wire electrode in a first direction until a first reciprocation position, stopping and inverting the traveling direction of the wire electrode, running the wire electrode in a second direction until a second reciprocation position, stopping and inverting the traveling direction of the wire electrode. A cutting process interruption sequence is carried out if a cutting process monitoring reveals that the cutting process must be interrupted, whereas the cutting process interruption sequence includes to continue the cutting process until the first or the second wire electrode reciprocation position, and to pause or to stop said cutting process at the wire reciprocation position.

摘要： A method for the machining of workpieces (11) and inspection of the processed workpiece surface in a machine tool (1), preferably a die sinking electrical discharge machine. The method uses at least one machining process interruption during which the processed surface of the workpiece (11) is inspected. Within said machining process interruption, at least one image of the processed workpiece surface is captured on the machine tool (1) by means of a digital camera (12). The images are processed by one or two pattern recognition algorithm (PRA D, PRA S), which were previously trained to determine the surface characteristics such as roughness parameters, functional surface features and/or characteristic defects of the processed workpiece surface captured on that at least one image. The determined surface characteristics are used to resume the processing of the workpiece surface with or without adjusting the processing parameters.
