Cone milling is one of the most common methods of milling in the pharmaceutical, food, chemical and associated industries. They are typically used for size reduction and deagglomeration or delumping of powders and granules.. Generally used for reducing material to a particle size as low as 180µm (80 mesh) a cone mill produces less dust and heat than alternative forms of milling.

CNC Milling Toolpaths at a Glance. CNC milling toolpaths are typically categorized as 2D, 3D, 4axis, and 5axis. However, the term 2D is a bit misleading since this toolpath uses the Zaxis to position a tool for depth. For example, in the image below, we have a prismatic part whose features all reside at various heights on the XY plane.
