Milling is a process of removing metal by feeding the work against a rotating multipoint cutter. The machine tool intended for this purpose is known as milling machine.

It is found in shops where tools and cutters are manufactured. The surface obtained by this machine tool is superior in quality and more accurate and precise.

Eli Whitney designed a complete milling machine in 1818. In the year 1861 Joseph Brown, a member of Brown and Sharp company developed the first universal milling machine.


1. The metal is removed at a faster rate as the cutter has got multiple cutting edges and rotates at a higher speed.
2. It is possible to perform machining by mounting more than one cutter at a time.
3. The table of the machine can be moved to an accuracy of 0.02mm.
4. It is very useful since various cutters and precise tools can be machined.
5. Special attachments can be mounted on the machine to perform operations that are performed in other machine tools.
6. The quality of the shop is enhanced with the presence of this machine.

What are the principles and features of "orbital technique" as applied to the EDM process?


1. The cost of the milling machine is high.
2. As milling cutters cost high, the investment for procuring tools is more.
3. The production cost will increase if we carry out the operations performed in a shaper or a drilling machine with a milling machine.


  1. You make a great point that using a milling machine is a great way to cut metal more quickly. This would save a lot of time in the engineering process and it also makes sense that you say the machine will improve the accuracy and precise measurements of your metal. If I need to cut and create a metal product in the future I will definitely think about using a milling machine because it gives me peace of mind to know that it has such high accuracy and quality.

  2. There are a ton of advantages to using milling machines when cutting metal. As the article points out, one of them is the precision. A milling machine can be moved millimeters at a time, ensuring complete accuracy when cutting.
