众所周知,线切割机床已在模具和零件加工领域获得广泛应用。但随着产品性能和质量的提高,对模具和零件的精度也提出了更高的要求。近十年来国内外对此不断地进行着研究,明显提高了线切割加工的精度。影响线切割加工精度的因素很多,除了机床、电源、控制系统外,还有工件材料、 As we all know, wire cutting machine tools and parts in the field of processing has been widely used. But with the improvement of product performance and quality, the precision of molds and parts is also put forward higher requirements. In the past ten years, this research has been continuously carried out at home and abroad, which has obviously improved the precision of wire cutting. Affect the accuracy of wire cutting many factors, in addition to machine tools, power supplies, control systems, as well as workpiece materials,
