Non-traditional processes
Machine tools for nontraditional machining techbology
New materials which have high strength to weight ratio,heat resistance and hardness such as nimonic alloys,alloys with alloying elements such as tungsten,molybdenum and columbium are difficult to machine by traditional methods.The complex shapes in these materials are either difficult to machine or time consuming by the traditional methods.In such cases,the application of the non-traditional machining processes finds extensive use.Further,in some applications a very high accuracy is desired besides the complexity of the surface to be machined.These processes are not meant to replace the conventional process but to supplement them.
There are a number of unconventional processes.they are:
1) Electrical Discharge Mchining (EDM)
2) Electro Chemical Machining(ECM)
3)Electro chemical grinding(ECG)
4)Ultrasonic machining(USM)
5)Laser Beam machining(LBM)
6)Chemical machining(CHM)
7)Abrasive Jet machining(AJM)
8)Water Jet machining(WJM)
9)Plasma arc machining(PAM)
