Question

difference between traditional & non traditional machining process

Answer 1

Laser Cutting
Laser Cutting-Non Conventional machining
Difference between Conventional and non-conventional machining processes are :
Conventional machining process involved tool wearing as there is a physical contact between the tool and the work piece. In non-conventional process, this is not the case.
Non-conventional tools are more accurate and precise than the conventional tool.
No noise pollution is created as a result of non-conventional methods as these tools are much quieter.
Tool life is long for non-conventional processing.
Non-conventional tools are very expensive than the conventional tools.
Non-conventional tools have complex setup and hence requires a skillful operation by expert workers, whereas conventional tools do not require any special expert for its operation and are quite simple in set-up.
Spare parts of conventional machines are easily available but not for non-conventional machines.
Extremely hard material can be cut easily with the help of non conventional machining but for conventional machining raw material should be less hard than cutting tool.
In conventional machining: Material removal takes place due to application of cutting forces – energy domain can be classified as mechanical. In Non Conventional Machining :Mostly NTM processes do not necessarily use mechanical energy to provide material removal. They use different energy domains to provide machining. For example, in USM, AJM, WJM mechanical energy is used to machine material, whereas in ECM electrochemical dissolution constitutes material removal.
Non Conventional machines can handle very complex jobs as compare to Conventional machining.
In Conventional machining because of scrap and chip formation more wastage of material .In case of non conventional machining no chip formation hence less scrap.
