The mechanism primarily responsible for mechanism of material removal in abrasive jet machining is:

Explanation:

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. The 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
• The nozzle directs the abrasive jet in a controlled manner onto the work material, so that the distance between the nozzle and the workpiece and the impingement angle can be set desirably
• The high-velocity abrasive particles remove the material by micro-cutting action as well as due to mechanical impact (brittle fracture) upon the work material.

Applications:

• For drilling holes of intricate shapes in hard and brittle materials
• For machining fragile, brittle and heat-sensitive materials

Limitations:

• MRR is rather low
• Abrasive particles tend to get embedded particularly if the work material is ductile
• Tapering occurs due to flaring of the jet
