摘要： PURPOSE:To perform surface processing with large corrosion resistance and large cohesion on an electrode used for ordinary discharge machining by inserting a material to be formed into a surface layer between a work and an electrode as powder and performing discharge machining. CONSTITUTION:Silicon powder 9 is mixed in a working liquid 8, the mixture is filled in a machining tank 6, air is fed to the machining tank 6 from an air pump 11, and a stirring action is applied to stir the silicon powder 9. A hydraulic cylinder device 12 is controlled by a servo-device 14, an electrode 4 is automatically and intermittently moved up and down, and the working liquid decomposed object and working powder generated by a discharge are diffused 7 between the work and electrode without being accumulated. When a discharge is performed under this condition, the surface layer of the work 5 is formed.

摘要： PURPOSE:To restrict sufficiently a lateral vibration of a wire electrode owing to the discharge reaction during the processing, and improve the processing accuracy, by furnishing an electromagnetic exciting unit, an oscillator, a pulley, a brake roller, and the like, and converting a tension imposed to the wire electrode periodically. CONSTITUTION:When a vibration of an electromagnetic exciting unit 1 is delivered to an oscillator 2, a pulley 3 is vibrated up and down. Since the wire passes through the pulley 3 after a specific tension is given to the wire by a brake roller 21, a new vibrating tension is given to the wire, and the tension of the wire varies vibrantly as a whole centering around the tension given by the brake roller 21. Therefore, in the wire oscillating system between an upper and a lower dices 26 and 26, the tension as the parameter of the system is converted to control the lateral vibration sufficiently. Consequently, the processing accuracy such as the accuracy of straightness can be improved.

摘要： PURPOSE:To automate the higher order processing in electric discharge machining and accomplish the same at higher speed by stopping the electric discharge machining for a workpiece the state being maintained, by measuring the roughness of the processed surface, and by comparing with the target roughness so as to serve for setting of the processing conditions thereafter. CONSTITUTION:The processing conditions setting stage for a series of machining control processes on the basis of on-the machine measurements includes studying functions such as alteration, addition, etc. of the data file itself on the basis of referencing to the processing data file and evaluation of the surface roughness, and there also the surface roughness measuring time is determined for the next time. Then a surface roughness sensor in measurements of surface roughness uses a differential transformer type and carries out with table movement by NC command in order to scan the surfaces of the workpiece 2 with a stylus 10. In evaluation of surface roughness, the max. value Rmax. square mean, surge, spectrum, etc. are placed as objects, which are calculated automatically by a computer. At this time, automatic recognition is also made for abnormal processing with arc electrodischarge etc., which should be reflected on setting of the processing conditions for the next stage to assure accomplishment of automated and high-speed processing.

摘要： PROBLEM TO BE SOLVED: To provide an electrode material with which higher speed machinability can be obtained in the field of electric discharge machining to perform machining using a copper electrode excellent in terms of electric conductivity, and machinability.
SOLUTION: The machining is performed by using a copper wire on which a film of copper oxide or cuprous oxide is formed on the surface or wire material of high tensile force on which the film of the copper oxide or cuprous oxide is formed on the surface and subjected to copper plating as a wire electrode. Also, in the wire discharge machining apparatus which performs the machining by generating electrostatic discharge in a gap with an opposed workpiece, a wire heating oxidation mechanism for depositing the oxide film on the wire electrode surface by heating the wire electrode in air or in an oxygen atmosphere is disposed on a wire traveling path upstream of the electric discharge machining point.
