摘要： A wire electrical discharge machine in which a profile directing unit controls a profile of a portion in the neighborhood of an approach point, which connects an approach path portion with a machining profile portion of the relative movement path of the wire electrode and workpiece on a machined face of the workpiece. A profile of a portion in the neighborhood of the approach point on the machined face of the workpieces can be adjusted to a desired profile according to the use of the workpiece.

摘要： A power supply unit for wire electrical discharge machining using an ac high-frequency power supply for applying an ac high-frequency voltage between a wire electrode (1a) and a workpiece (2) includes a high-frequency oscillation and amplification circuit (4) and a pulse power supply (5) which is an ac-high-frequency-voltage intermittently supplying unit for effecting the application of the ac high-frequency voltage between the electrode and the workpiece and a pause thereof. In wire electrical discharge machining using this power supply unit for wire electrical discharge machining, it is possible to suppress the vibration of the wire electrode (1a) due tog the electrostatic force acting between the wire electrode (1a) and the workpiece (2), making it possible to improve the straightness accuracy of a machined surface of the workpiece (2) and make surface roughness small.
