摘要：

A high-frequency AC power supply is used for the finishing process by Wire Electrical Discharge Machine, and can achieve super-fine finish and straightness. But the mean gap voltage while machining is 0 volt, which makes difficult to capture the discharge gap voltage for proper feed rate control. It is one of major problems for super-fine profiles. By adding a new electrical circuit between the workpiece and the wire electrode, the discharge gap voltage is properly detected, and the feed rate can be controlled properly. This new method helps the improvement of the accuracy with super-fine profiles such as IC lead frame stamping die, etc.
