Question

Advantages of non conventional machining processes

Answer 1

Non conventional Machining is a recent development in machining techniques. It is based on unconventional machining techniques using Laser beam, Electron beam, Electric arc etc. Conventional machining involves the direct contact of tool and work -piece, whereas unconventional machining does not require the direct contact of tool and wor piece. Conventional machining has many disadvantages like tool wear which are not present in Non-conventional machining

Advantages of Non-conventional machining:
1) High accuracy and surface finish
2) no direct contact of tool and workpiece, so there is less/no wear
3) tool life is more
4 ) quieter operation

Disadvantages of non-conventional machining:
1) high cost
2) complex set-up
3) skilled operator required

Answer 2

Answer:

• An innovative technique called non-conventional or non-traditional machining is utilised to get around the drawbacks of traditional machining techniques.
• The non-traditional machining techniques, which were comprehensively, include ultrasonic machining, laser beam machining, water jet machining, abrasive water jet machining, electron beam machining, etc.
• The non-Traditional machining approach is a cutting-edge technique used to solve the issues with traditional machining approaches.

NECESSITY OF UNCONVENTIONAL MACHINING METHODS

a) Materials that are extremely hard and brittle or tough to machine are challenging to work with using conventional machining techniques.

b) When the workpiece is insufficiently flexible or thin to withstand the forces used in cutting or grinding

c) When the part's form is very complex

BENEFITS OF NON-CONVENTIONAL MACHINING TECHNIQUES :

High precision

• Whether they are small- or large-scale, industries today place a high priority on precision.
• When compared to items made using non-traditional ways of machining, those made using conventional processes are less accurate.
• Therefore, unconventional machining is appropriate for the present era and serves as a replacement for conventional machining methods thanks to its high accuracy.

Less noise:

• Because they are a better alternative to conventional machining techniques, non-traditional machining techniques significantly contribute to lowering the noise pollution of the neighbourhood.
• Because the process involved is silent, certain non-traditional machining facilities can be located in residential areas.

High production:

• When compared to standard ways of machining, modern or unconventional techniques encourage a high production rate.
• This is due to the fact that non-traditional methods' working processes are quicker and more precise than those of traditional approaches.

Less waste product:

• Using conventional machinery makes it very difficult to manage waste product. It takes extra work to dispose of the chips created in a timely manner.
• But when using non-traditional machining techniques, either no waste is produced, or if it is, it is small and simple to handle and dispose of.

No tool deterioration:

• In non-traditional machining techniques, there is no contact between the tool and the workpiece, hence there is no tool wear.
• As a result, there is no chance of tool failure and no tool wear and tear.
