【摘要】 为了提高不锈钢板电火花线切割加工的切割速度和表面加工质量，并进一步降低电极丝损耗，提出了一种基于串联供液的不锈钢板多层叠加电火花线切割新工艺。该工艺较采用常规供液加工的切割速度提高了24.70%，表面粗糙度值降低了32.11%，电极丝损耗降低了83.88%。研究表明，串联供液技术通过将极间压差流与剪切流进行同向复合，显著提升了极间流体的流速与流量，从而增强了排屑能力并扩大了放电间隙。该技术有效地改善了极间放电条件，抑制了局部放电现象，显著提高了放电稳定性，为电火花加工工艺的优化提供了重要支持。更多还原

【Abstract】 A new technology based on series liquid supply WEDM of stainless steel plates using multi-layer stacking was proposedin order to increase the cutting speed and surface quality of wire cut electrical discharge machining of stainless steel plate and fur-ther reduce the wire electrode wear. Compared with conventional liquid supply,the cutting speed was increased by 24.70 %,thesurface roughness was reduced by 32.11 % and the electrode wire loss reduction was decreased by 83.88 % under the newprocess. The study found that the series fluid supply technology significantly improved the velocity and flow rate of the inter-elec-trode fluid,enhanced the chip removal ability and expanded the discharge gap by combining the pressure differential flow andshear flow in the same direction. This technology effectively improved the inter-electrode discharge conditions,inhibited partialdischarge phenomenon,significantly increased the discharge stability and provided important support for the optimization of elec-trical discharge machining processes.更多还原
