Abstract
The micromillgrinding tool is a compound tool that has both micromilling and microgrinding abilities Local electroplating was employed to fabricate micromillgrinding tools with CBN abrasive The grits topography of the flank face was measured and the graphical investigation was carried out to evaluate the distribution of the grits It is found that the coatings were well electroplated and the abrasive grains were distributed more evenly on the 15mm tool than on the 09mm tool The experiments were performed to evaluate the machining characteristics of the micromillgrinding tool The machined surface roughness and the forces were measured and the effects of processing parameters on surface roughness were analyzed The tool wear style was investigated The results show that the surface topography of micromillgrinding is similar to that of microgrinding Under the same conditions its surface roughness is better than that of micromilling but worse than that of microgrinding The grits on the tool flank face lead to the decrease of the normal force but the increase of the tangential force in machining The wear style of micromillgrinding tool is mainly abrasive grain shedding
