The effect of dressing parameters on micro-grinding of titanium alloy.
Artikel i vetenskaplig tidskrift, 2018

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-6Al-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.
