Experimental study of the surface roughness of hardened tool steel Böhler W300 milled by micro square endmills
conference paper
Surface roughness is a key parameter in evaluation of engineering surface in macro scale; in case of micromilling, it is of even greater importance because the magnitude of the roughness can be comparable with the workpiece tolerance, and will have a direct impact on the quality of the microproducts. This paper presents the preliminary results of experimental investigations on micromilling process. In this study, the influence of machining parameters on the surface roughness in micromilling was studied and compared with the observations in former researches. Besides, it was found that in microscale the roughness is largely influenced by the tool runout; runout has the
effect to increase the effective feed per tooth. For conventional milling, roughness can be used for tool wear criteria; however in the experiments, no obvious relation was found between wear of
micro endmills and workpiece surface roughness.
