对于众所周知的“难加工”航空航天材料，人们对高效/高质量的加工策略有着强烈的需求。目前加工这些材料的方法主要是机械切削方法，由于刀具成本高、表面质量差以及可加工的工件特征和操作的限制，机械切削方法成本高昂。最新的电火花加工技术或许能够解决机械加工方法中遇到的问题。本文采用电火花加工技术加工钛合金Ti-6Al-4V，研究Ti-6Al-4V的热性能和电性能对电火花加工生产率的影响。在研究中，对不同占空比的Ti-6Al-4V工件进行了温度测量，以阐明钛合金加工困难的根本原因，并观察生产率和质量方面的最佳占空比。 (C) 2007 Elsevier B.V. 保留所有权利。
There are strong needs for productive/quality machining strategies of notoriously "difficult-to-machine" aerospace materials. The current means of machining these materials is dominated by mechanical cutting methods, which are costly due to high tooling costs, poor surface quality and limitations in the workpiece features and operations that can be machined. The newest EDM technology may be able to circumvent problems encountered in mechanical machining methods. In this paper, the EDM technology has been used to machine titanium alloy Ti-6Al-4V to investigate the effect of Ti-6Al-4V's thermal and electrical properties on the EDM productivity. In the study, temperature measurements have been made for Ti-6Al-4V workpieces with various duty factors to clarify the essential causes of difficulty in machining titanium alloys and observe the optimal duty factor in terms of productivity and quality.
