中文摘要：
为了提高微细电火花加工效率,通过分析微细电火花加工特点,改进了主放电回路,设计了一种基于现场可编程门阵列（FPGA）的微细电火花加工脉冲电源.该电源集成了放电状态检测功能,能够判断每一个脉冲的放电状态,并及时切断有害脉冲.设计了应用于微细电火花加工的清扫脉冲回路,可在极间加载高能量窄脉宽的清扫脉冲,以清除积聚在极间的加工屑.利用该电源在桌面式微细电火花加工机床上进行了微细深孔加工实验和微细孔极限加工实验,取得了较好的加工效果.
英文摘要：
Aiming at improving the efficiency of micro electrical discharge machining（EDM）,the characteristics of micro-EDM was analyzed,the main discharge circuit was improved,and a pulse generator for micro-EDM based on FPGA was developed.The function of gap status detection is integrated that every single pulse can be detected and the harmful discharge pulse can be cut off in time.A sweep pulse circuit was designed.The debris can be evacuated out of the discharge gap by the exploding effect of the sweep pulses,and the gap status can be improved.With this pulse generator,a preferable result is achieved in the experiment of machining of a deep micro-hole on a CNC controlled desktop micro-EDM machine.
