研究了修整参数和切削速度对Ti-6A 1 - 4V钛合金微磨削性能的影响。首次采用极高的修整重叠率对研磨针进行修整，发现在研磨针表面测量得到的微观形貌与研磨力直接相关。更具体地说，法向和切向磨削力分量都随着修整重叠率的增加而增加。还介绍了修整对表面质量的相关影响。用包含更精细形貌的销进行研磨伴随着更少的切屑负载，因此具有更好的表面光洁度。此外，向下修整方法产生更粗糙的成品表面质量和诱导较低的磨削力相比，向上修整。高值的修整重叠比（高达1830），在向上修整的方法，改善了表面光洁度显着。
This paper is concerned with investigating the effects of dressing parameters and the effect of the cutting speed on the performance of micro-grinding of titanium Ti-6A1-4 V alloy. Extremely high dressing overlap ratios were used for the first time to dress the grinding pins, and the obtained micro-topography, measured on the surface of the pins, is found to be directly related to the grinding forces. More specifically, both the normal and tangential grinding force components increased with the dressing overlap ratio. Related effects of dressing on surface quality are also presented. Grinding with pins containing finer topography was accompanied by less loading with chips and hence a better surface finish. Moreover, down-dressing method generated rougher finished surface quality and induced lower grinding forces compared to the up-dressing. High values of the dressing overlap ratio (up to 1830) in the up-dressing method improved the surface finish significantly.
