In upward ramping, tangential curve is placed on the one side from the axis of rotation of ball nose end mill.In downward ramping, tangential curve is placed around the axis of rotation of ball nose end mill on the both sides, and crosses the c enter of rotation of ball nose end mill.The scheme with symbols for ramping is shown in fig.2.
The ball end mill insret tool further comprises a curved cutting face, and a plurality of face serrations formed along the curved cutting face.Each face serration has a face ridge and a face valley forming the serrated curved cutting blade.Problem to be solved to provide a plurality of shear angles over an extensive part of a cutting blade.

The basic geometrical components of the ball part of a ball end mill are depicted in workpiece coordinates, oxyz, as shown in fig.1a.The ball part is machined using a grinding wheel, as shown in fig.1b and c.The rake face and the flute surface are generated by the side face and the revolution surface of the grinding wheel, respectively fig.1b.
They cut best using the side of the mill, so most cutting software will slowly ramp the end mill down into the material, rather than a simple plunge.With fishtail end mills, you will have nice square corners at the bottom of any inset section of geometry and a smooth, flat surface anywhere it passes over the top of.
