A fixture holds and positions the work but does not guide the tool. Whereas a jig holds, locates and as well as guides the tool. The fixtures are heavier in construction and are bolted rigidly on the machine table. Whereas the jigs are made lighter for quicker handling, and clamping with the table is often unnecessary.

Ball milling is a mechanical technique that is broadly used to grind powders into fine particles [134–141]. 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].

Climb vs. Conventional Milling When milling, one should be aware of the difference between conventional, and climb milling. In conventional milling, the workpiece is fed into the rotation of the cutter. This type of cut requires lower forces and is preferred for roughing cuts. In climb milling, the work moves with the rotation of the cutter.
