2. What is Milling?
• Milling is the machining process of using rotary cutters to
remove material from a workpiece advancing (or feeding)
in a direction at an angle with the axis of the tool. It
covers a wide variety of different operations and
machines, on scales from small individual parts to large,
heavy-duty gang milling operations. It is one of the most
commonly used processes in industry and machine shops
today for machining parts to precise sizes and shapes.
3. MILLING MACHINE
• Milling machines are very versatile. They are usually used to
machine flat surfaces on square or rectangular parts, but can
also produce many unique and irregular surfaces.They
can also be used to drill, bore, produce slots, pockets and many
other shapes.
• A milling machine removes metal by rotating a multi-toothed
cutter that is fed into the moving workpiece. The spindle can
be fed up and down with a quill handle on the head.
• A milling machine is a power driven machine that cuts by
means of a multitooth rotating cutter. The mill is constructed in
such a manner that the fixed workpiece is fed into the rotating
cutter. Varieties of cutters and holding devices allow a wide
rage of cutting possibilities.
4. PRINCIPLE OF MILLING
MACHINE
Milling operates on the principle of rotary motion. A milling
cutter is spun about an axis while a workpiece is advanced
through it in such a way that the blades of the cutter are able to
shave chips of material with each pass.
