Material removal takes place in Abrasive Jet Machining due to

Explanation:

Abrasive jet machining (AJM)

• Abrasive jet machining (AJM) removes material through the action of a focused stream of abrasive-laden gas.
• Micro-abrasive particles are propelled by inert gas at velocities of up to 1000 ft/sec.
• When directed at a workpiece, the resulting erosion can be used for cutting, etching, cleaning, deburring, polishing, and drilling.
• As the high-speed abrasive particles impact the surface, kinetic energy converted into impact energy and erodes the material and gas carries fractured particles away. AJM is especially effective on hard, brittle materials such as glass, silicon, tungsten, and ceramics.
• Soft, resilient materials, such as rubber and some plastics, resist the chipping action and thus are not effectively processed by AJM.
• No workpiece chatter or vibration occurs with this process because the large quantity and small mass of the abrasives result in uniform loading of the part.
• This further enables AJM to produce fine, intricate detail in extremely brittle objects.
• The AJM-processed eggshell shown in the Figure provides a graphic example of the delicate nature of the process.
• In addition, because heat is carried away by the abrasive propellant gas, workpieces experience no thermal damage.
