We studied tool life, flank wear, and machined surface roughness in the high-speed milling of hardened steel on a small ball end mill using a high-speed milling machine. We found that: (1) Cutting edge flank wear increases in proportion to cutting length and the flank wear shape gradually has a resembalance to the shape of the actual cutting length. (2) Long tool life depends on stepdown pick-feed and down-milling conditions. (3) Surface roughness increases in proportion to cutting length, but a low surface roughness of 1.4 μm is obtainable for a 3,800 m cutting length in down-milling. (4) CBN tool flank wear is very low -- at least 1/15 th that of carbide tools under down-milling conditions, and a surface roughness of 1.6 μm is obtainable for a 67.2 km cutting length. We verified the effectiveness of CBN tools in high-speed milling of hardened steel under cutting conditions.

In order to improve efficiency of high speed milling, effects of pick feeds of up cutting and down cutting on tool wear and processing characteristics were investigated after cutting pre-hardened steel NAK 55 by TiAlN-coated carbide radius end mill. Flank wear of the tools after up cutting was less than down cutting when the pick feed was smaller than 0.1 mm, which tendency changed when the pick feed was larger than 0.3 mm.
