Abstract
Procedimiento de mecanizado por electroerosión según el cual se mecaniza una pieza por medio de la herramienta (1) separadas una de la otra por una distancia de mecanizado (L) de un espacio de trabajo (G) en el cual se encuentra un fluido de mecanizado en el que aplicando una tensión eléctrica entre la herramienta y la pieza para engendrar unas descargas erosivas, caracterizado por la sucesión siguiente de fases durante una descarga erosiva: a) una fase de espera (tD) durante la cual una tensión alterna se aplica entre la herramienta (1) y la pieza (2) a una frecuencia tal que los iones presentes en el fluido de mecanizado (3) efectúan unos recorridos oscilantes (P2) sensiblemente más cortos que dicha distancia de mecanizado (L) que separa la herramienta de la pieza y durante la cual se crea un canal ionizado entre la herramienta y la pieza por el efecto de dicha tensión alterna, b) una fase de chisporroteo (tA) que se inicia con la detección de una corriente que circula entre la herramienta y la pieza y durante la cual una fuente de tensión continua (4) forma y mantiene una corriente de descarga erosiva (14) y c) una fase de pausa (tB) durante la cual no se aplica ninguna tensión entre la herramienta (1) y la pieza (2) de forma que el fluido de mecanizado (3) presente entre la herramienta y la pieza se desioniza y el canal ionizado desaparece; y porque se repite esta sucesión de fases durante la duración del mecanizado.
