ABRASIVE JET MACHINING | PPT

7. WORKING OF AJM Abrasive jet machining is a process in which material removal takes place due to erosive action of a stream of fine-grained abrasive particles impacting at high velocity on the work surface. Fine-grained abrasive particles mixed in suitable portion with high pressure carrier gas, usually air, are directed through a suitably designed nozzle.

ABRASIVE JET MACHINING

In Abrasive Jet Machining (AJM), abrasive particles are made to impinge on the work material at a high velocity. The jet of abrasive particles is carried by carrier gas or air. High velocity stream of abrasive is generated by converting the pressure energy of the carrier gas or air to its kinetic energy and hence high velocity jet.

Abrasive machining | PPT

13. • Ultrasonic machining is a subtractive 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. The tool travels vertically or orthogonal to the surface of the part at amplitudes of 0.05 to 0.125 mm (0.002 to 0.005 in.).
