摘要： In a wire electric discharge machine, a discharge delay time is used to classify the inter-electrode state into three categories; a short-circuit state, small-gap state, and large-gap state. Based on this classification, the magnitude of a machining current supplied from a main discharge circuit is determined. If the discharge delay time is zero (i.e., if no electric discharge is generated) after the lapse of a predetermined time since the start of the application of a machining voltage to an inter-electrode gap by an auxiliary discharge circuit, the inter-electrode gap is determined to be short-circuited by machining chips. Thereupon, a short-circuit machining current is supplied from the main discharge circuit to the inter-electrode gap to remove the machining chips. In this way, establishment of a complete short-circuit state is prevented so that the machining efficiency is improved to increase the machining speed.
摘要翻译：在电火花线切割机中，使用放电延迟时间来将电极间状态分为三类：短路状态，小间隙状态和大间隙状态。基于这种分类，确定从主放电电路供应的加工电流的大小。如果从开始通过辅助放电电路向电极间间隙施加加工电压起经过预定时间之后放电延迟时间为零（即，如果没有放电发生），则电极间通过加工芯片确定间隙被短路。于是，从主放电电路向电极间间隙提供短路加工电流，以去除加工芯片。以这种方式防止了建立完整的短路状态，从而提高了加工效率，从而提高了加工速度。
