叶序排布外圆砂轮磨削TC4的磨削力实验研究

摘要

为了获得有序化排布超硬磨料砂轮的磨削性能,以及实现磨削难加工材料钛合金的可行性,基于生物学中的叶序排布理论设计一种新型的有序化排布超硬磨料砂轮,即叶序排布砂轮,并利用其和错位排布砂轮及无序排布砂轮对钛合金TC4进行磨削实验,分析了它们的磨削力随着进给速度和磨削深度的变化规律.实验结果表明:在相同的磨削实验条件下,磨粒叶序排布砂轮的磨削力小于错位排布砂轮和无序排布砂轮.%In order to obtain the grinding performance of the super-abrasive grinding wheel and realize the feasibility of grinding the Titanium alloy,a new kind of the super-abrasive grinding wheel with phyllotactic pattern was designed based on the phyllotaxis theory of biology.And the experiment of grinding the Titanium alloy TC4 was carried out with different grinding wheels.The changing rules of the grinding force with the feed speed and the grinding depth were analyzed.The results show that under the same experiment conditions,the grinding force of the grinding wheel with abrasive phyllotactic pattern is smaller than those with staggered and random pattern.
