Ball milling is a mechanical technique that is broadly used to grind powders into fine particles [134141]. The reactants are generally broken apart using solvent molecules in the traditional method; but in ball milling, reactants are broken by using mechanical forces. The term mechanochemistry has been introduced very recently [142].

This article explores the differences between CNC turning vs. CNC milling and how Autodesk Fusion can be a gamechanger for machinists in both realms. We'll largely discuss 2D turning and milling, ignoring machines and processes where turning and milling can seem to blend into one complex process instead of two distinct ones.

Unlike an end mill, a ball nose milling cutter uses a cutting tool that rotates and cuts the material. The chip size depends on several factors, including the cutter's rotation speed and feed rate. With a ball nose milling cutter, chip size will be less than half of the radius of the workpiece. A smaller cutter will reduce the possibility of swarf.
