摘要/Abstract

摘要：

钛合金在放电诱导和助燃氧气的共同作用下能通过自身燃烧反应被蚀除,随着助燃氧气压力增大,钛合金蚀除速度增大,但是当气体压力增大到一定程度时会发生爆炸,影响材料成形精度。针对钛合金放电诱导烧蚀高效车削加工提出了基于可控燃爆机理的新加工理念,即通过定量高压复合低压进气系统以实现钛合金在加工过程中处于可控燃爆状态,以增加钛合金蚀除速度。并与只通入低压氧气的加工方式进行对比试验。结果表明:基于可控燃爆机理的车削加工,在保证加工精度的前提下,通过间歇定量高压助燃氧气实现钛合金燃爆的可控高效加工,其蚀除速度远远高于只通入低压氧气的放电诱导烧蚀车削。

Abstract:

Titanium alloy can be removed through its own combustion reaction under the conditions of electrical discharging and combustion-supporting oxygen. With the combustion-supporting oxygen pressure increasing, the erosion rate of the titanium alloy increases. But it will explode when the oxygen pressure increases to a certain extent. The material forming accuracy will reduce. A new processing concept is proposed based on the controllable melting and explosion mechanism for the efficient turning induced by electrical discharge machining (EDM). The concept can keep titanium alloy processing in the controllable melting and explosion condition to increase its corrosion removing rate through the induction system of quantitative high-pressure composite low-pressure, which is compared with the machining method that only passes into the low-pressure oxygen. The results show that the corrosion removing rate of controllable efficient processing of titanium explosion with intermittent quantitative high-pressure combustion oxygen, which is based on turning composite machining with controllable melting and explosion mechanism, is much higher than that of only spark-induced combustion turning machining with low-pressure oxygen.

Key words: titanium alloys, electrical discharge machining, controllable melting and explosion, efficient, corrosion removing
