Introduction to 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 ...

This utilizes plain milling cutters, and both wide and narrow cutters may be used. Wide cutters are ideal for large surface areas, whereas narrow cutters can create deeper cuts. Face Milling. Last but certainly not least, in face milling the cutting tool is positioned perpendicular to the surface of the material that is being worked on.

Cutting Types. 1. Milling; 2. Lathe Processing; Cutting is a technique where the operator moves a material (workpiece) such as metal and the tool in relation to each other in order to shape the workpiece into the desired form through shaving, drilling, etc. Cutting can be broadly divided into two methods: rolling, where the workpiece is restrained while the tools turn, and turning, …

Milling Machine Definition: The milling machine is a type of machine which removes the material from the workpiece by feeding the work past a rotating multipoint cutter.The metal removal rate is higher very high as the cutter has a high speed and many cutting edges. It is the most important machine in the tool room as nearly all the operations can be performed on it with high accuracy.

End Milling. End milling is probably the most common class of operations performed on milling machines. End mills are cylindrical cutters that normally have two or more cutting edges on both the periphery and end of the tool. End milling operations include side milling, slotting, facing, or partial facing, pocketing, profiling, and contouring.

Milling cutters with keyed holes are predominantly for use in horizontal mills. End mills are designed for cutting slots, keyways and pockets. Two fluted end mills can be used to plunge into work like a drill. End mills with more than two flutes should not be plunged into the work. Ball end mills can produce a fillet.
