What is Conventional and Unconventional Machining?

Machining means a metal removal process. The conventional/traditional machining processes performed on machines such as lathe, drilling, milling, slotting, planning, etc. require the continuous involvement of the operator. The operators need to maintain the contact between tool and workpiece whereas in a non-traditional machining process there is no contact between the two and it is usually a fully automated process. 

Advantages and Disadvantages of Non-traditional over traditional Machining

In unconventional, unlike conventional machining, there is no requirement for sharp cutting edges in the tool and no constraints on tool hardness thereby the life of the tool is longer. In unconventional machining, the byproduct comes usually in the form of powder unlike conventional where chips are formed. The advantages of non-traditional machining over traditional provide high surface finish and accuracy, very less noise pollution, high metal removal rate, as compared to conventional machining and it can produce prototypes parts very effectively. 

Though it has many advantages, there are a few disadvantages also as compared to the traditional machining process. The process is a high set up cost, high production cost, complex setup equipment, cannot be employed for mass production and it requires a very skilled operator. 

Techniques in Non-conventional Machining

There are several techniques in unconventional machining used to remove the excess material from the workpiece which works on the mechanical, thermal, electrical, and chemical energies and their combinations. The methods based on thermal energy are namely EDM (Electrical discharge machining), LBM (Laser beam machining), PAM (Plasma Arc machining), EBM (Electron beam machining), and IBM (ion beam machining). 

Not only this, but the process also includes Machining based on Electro-chemical energy the methods are classified as ECM (Electro-chemical machining), ECG (Electro-chemical grinding), ECH (Electrochemical Honing), ECD (Electro-chemical debarring), etc.
