AI Technical Summary
Existing wire electrical discharge machines face challenges in enhancing machining speed while preventing frequent breakage of the wire electrode, which occurs when the machining current is too large.
A control method for a wire electrical discharge machine that determines the discharge gap state and adjusts the machining current accordingly. The method includes determining the discharge gap state among normal, short-circuited, and open states, recording these states, setting the machining current based on previous states, and controlling the main discharge circuit to supply appropriate currents depending on the current state.
The method allows for setting a machining current that enhances machining speed while effectively reducing the risk of wire electrode breakage, thereby improving machining efficiency and accuracy.
