A Review of the Main Modeling Methods for Ball Nose End
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

A typical machine with Pallets allows you to be setting one or more Pallets up while the machine is working on another. A Pallet change operation cycles the old Pallet outside of the machine s milling area and brings the new one in. This minimizes the time the machine has to be offline and allows Setup to be done in parallel with machining.
