Abrasive jet machining interview,viva, oral question and answers for Mechanical students 1. What is the principle behind abrasive jet machining? A jet of inert gas consisting of very fine abrasive particles strikes the work piece at high velocity (usually between 200400 m/sec) resulting in material removal through chipping / erosive action.
Principle of AJM Abrasive jet machining process uses the mix of finegrained abrasive material with any suitable gas or air for metal cutting. High pressured particlegas mixture is directed in a controlled manner by using specially designed nozzles and made them impinge onto workpieces.
