Metalworking - Wikipedia

Milling is the complex shaping of metal or other materials by removing material to form the final shape. It is generally done on a milling machine, a power-driven machine that in its basic form consists of a milling cutter that rotates about the spindle axis (like a drill ), and a worktable that can move in multiple directions (usually two dimensions [x and y axis] relative to the workpiece).

Calorimetric and morphological studies of .

The mechanical alloying process via the rod-milling technique is classified into three stages of milling. At the early stage of milling, the elemental powders of Al and TM are grown to form layered-composite particles of a larger diameter as a result of cold welding. At the intermediate stage, a complete crystalline-to-amorphous transformation ...

Milling Machine: Methods of Milling. Milling .

Milling is an important process of manufacturing technology and basically it refers to the removal of metal from the work piece using a tool which has several cutting points and is rotating about its axis. Thus each cutting point removes a little bit of the metal but since there are multiple such points and the tool is rotating at a fast speed, the overall removal is quite brisk.
