TLDR
In this paper, an electrical discharge detecting circuit, a timing controller, a normal discharge driver, an arc discharge driver circuit, normal discharge switch elements and arc discharge switch element are used to improve the performance of a conventional wire cut EDM.Abstract:
It is a main object of the present invention to improve the drawback of a conventional wire cut EDM which controls the pulse width of discharging current to supply discharge energy under the state of constant current slope. The discharging current slope control method and device of the wire cut electrical discharge machine of the present invention comprises an electrical discharge detecting circuit, a timing controller circuit, a normal discharge driver circuit, an arc discharge driver circuit, normal discharge switch elements and arc discharge switch elements. The slopes of the output triangle waveform currents shall be variable due to the different results of detecting by the electrical discharge detecting circuit, depending on normal discharge or arc discharge condition, to render the current slope of the arc discharge smaller than the current slope of the normal discharge, so as to achieve the effect of keeping a high machining speed without easily breaking of the wire electrode.read more
