Cutting Length

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.

Quality Surface

This study deals with 5-axis control tool path generation to create microshapes dexterously and efficiently, while maintaining quality. Concerning 5-axis control machining, the use of ball end mills is generally employed. However, this method needs a lot of time to obtain high quality surface. To solve this problem, a side cutting edge of the ball end mill is positively utilized with its parallel to the ruled surface. Therefore, a new CAM system is developed to detect the surface to be machined with the side cutting edge, and to generate collision-free tool paths between the tool and the work piece. The effectiveness of the developed CAM system is experimentally confirmed by creating a tiny Möbius ring.
