Abstract
Official abstract text for this publication.
A primary power supply charges a capacitor by turning on a switching element and, upon completion of charging, turns off the switching element. Then, an AC pulse voltage is applied to the gap between a wire electrode and a workpiece by alternately turning on and off a switching element present in a secondary power supply. After a dielectric breakdown occurs between the wire electrode and the workpiece, the switching element is turned on to connect the capacitor so that the capacitor supplies a pulse current for machining.
First claim
Opening claim text (preview).
The invention claimed is: 1. A wire electric discharge machine for machining a workpiece into a desired shape by changing a relative position between a wire electrode and the workpiece while causing discharge by applying a voltage to a machining gap between the wire electrode and the workpiece, the wire electric discharge machine comprising: a secondary power supply including a DC power supply and a switching element, wherein the secondary power supply is configured to apply an AC…
