Ultrasonic machining thesis

Ultrasonic machining, or strictly speaking the ultrasonic vibration machining, is a subtraction manufacturing process that removes material from the surface of a part through high frequency, low amplitude vibrations of a tool against the material surface in the presence of fine abrasive particles. Abstract as per of our design we have classified the parts which are contained in our design the jet cutting machine works on principle of cutting all types and different shaped material with optimum surface finish and material removal rate.
