Ramping refers to simultaneous radial and axial motion of a cutting tool, making an angular tool path. Oftentimes, this method is used to approach a part when there is a need to create closed forms such as pockets, cavities, engravings, and holes. In doing so, the need to plunge with an end mill or drill to create a starting point is eliminated.
For ball nose optimization (and in addition to tilting the tool), it is highly recommended to feed the tool in the direction of the incline and utilize a climb milling technique. To properly employ a ball nose end mill with a tool angle and gain the most optimal tool life and part finish, follow the 2-step process below.

The large initial sample is then crushed between each stage and fed to the succeeding sampling unit by a shaking pan or vibratory feeder. Uniform feeding helps insure more accurate sampling by reducing surges, segregation and synchronism in the system. The final sample is a percentage of the total feed such as 10%, 5%, 1.0%, 0.05% or less.
