Roughing and finishing 3D pockets with closed angles
Closed angles; less than 90 degrees, are a common component feature in pockets and cavities. Depending on the stability of machine set-up, the slicing method using CoroMill® Plura ball nose end mill is the best choice.
A machine with 4 or 5 axes is needed to machine a closed angle. 4 axes: If only one side of the pockets has a closed angle and the bottom shape is flat. 5 axes: if there is a corner with closed angles on both sides and a radius at the bottom profile.
The conical ball nose end mills give the choice for high quality surface finish.
