摘　　要：文中研究了在大气和乳化液两种介质中,走丝速度对高速走丝电火花线切割精加工的影响。实验结果表明,气中线切割加工具有加工表面直线度好、加工速度(材料去除率)高等优点。另外还发现,无论气中或液中加工时,随着走丝速度的提高,加工速度都明显增大,而同时使加工表面的直线度变差。This paper studies on the influence of winding speed on finishing high-speed wire electrical discharge machining (WEDM) in atmosphere and emulsion dielectric. Experiment results showed that WEDM in atmosphere offers advantages such as better straightness and higher material removal rate. It was also found that the material removal rate increased significantly at a higher winding speed, with the straightness got worse at the meanwhile both in atmosphere and emulsion dielectric.
