微细电解线切割加工是一种微细加工新方法。本文基于电化学原理,分析了微细电解线切割加工控制系统的要求,利用虚拟仪器设备搭建了加工控制系统,并在Labwindows/CVI软件平台上设计了控制系统软件。本系统通过控制线电极按照DXF图形文件中的轨迹伺服进给,电解腐蚀工件材料达到制造微小零件的目的。试验表明本系统具有稳定可靠、硬件简单、灵活性好等特点。 Micro-electrolysis wire cutting is a new method of micro-machining. Based on the principle of electrochemistry, this paper analyzes the requirements of micro-electrolysis wire-cutting processing control system, and uses the virtual instrument equipment to build the processing control system. The software of the control system is designed on Labwindows / CVI software platform. The system through the control line electrode DXF graphics file in accordance with the track servo feed, electrolytic corrosion of the workpiece material to achieve the purpose of manufacturing tiny parts. Experiments show that the system is stable and reliable, hardware is simple, flexible and so on.
