  • A Review of the Main Modeling Methods for Ball

    The ball nose end mills are highly used for complex sculptured surfaces in 3-5 axes milling. The modeling of the cutting process using ball nose end mills is more complex than in the case of simple end mills due to the fact that the cutting speed varies continuously along the cutting edge. By tilting the cutting tool relative to the surface to be machined, the modeling is getting more ...
