Abstract

Owing to low machining efficiency, poor machining accuracy, and surface quality in traditional electrical discharge machining (EDM) of TC4 titanium alloy holes, an EDM trepanning method was developed using a deionized water medium and a flushing liquid in tube electrodes (denoted by EDM-TFD). Several experiments and research mechanisms were conducted on EDM-TFD. Compared with traditional EDM, ED milling, and EDM trepanning, EDM-TFD featured increased hole machining efficiency by more than five times, improved machining taper by more than 57%, and improved surface quality by more than 40%. The optimal processing technology was determined through process experiments using copper tube electrodes, a flushing liquid with a speed of 2 m/s, pulse width (Ton) of 150 μs, pulse interval (Toff) of 150 μs, and peak current (Ip) of 15 A. Under the optimized process, the hole exhibited a feed rate of 1.1 mm/min, machining efficiency of 38 mm3/min, machining taper of 40 μm, and surface roughness of 5.2 μm.

TC4 钛合金孔的高效放电加工桁架技术研究
由于传统的 TC4 钛合金孔放电加工(EDM)存在加工效率低、加工精度和表面质量差的问题,因此开发了一种在管状电极中使用去离子水介质和冲洗液的 EDM 穿孔方法(简称 EDM-TFD)。对 EDM-TFD 进行了多次实验和研究。与传统的电火花加工、电火花铣削和电火花穿孔相比,EDM-TFD 的孔加工效率提高了 5 倍以上,加工锥度提高了 57% 以上,表面质量提高了 40% 以上。通过使用铜管电极、速度为 2 m/s 的冲洗液、150 μs 的脉冲宽度 (Ton)、150 μs 的脉冲间隔 (Toff) 和 15 A 的峰值电流 (Ip)进行工艺实验,确定了最佳加工技术。在优化工艺下,孔的进给速度为 1.1 mm/min,加工效率为 38 mm3/min,加工锥度为 40 μm,表面粗糙度为 5.2 μm。

期刊介绍: The International Journal of Advanced Manufacturing Technology bridges the gap between pure research journals and the more practical publications on advanced manufacturing and systems. It therefore provides an outstanding forum for papers covering applications-based research topics relevant to manufacturing processes, machines and process integration.
