Question

In abrasive jet machining, as the distance between the nozzle tip and the work surface increases, the material removal rate

• A. increases continuously
• B. decreases continuously
• C. decreases, becomes stable and then increases
• D. increases, becomes stable and then decreases

Answer 1

The correct option is D increases, becomes stable and then decreases

In abrasive jet machining the variation is as shown


MRR= Metal removal rate
NTD = Nozzle tip distance

In abrasive jet machining, as the distance between the nozzle tip and the work surface increases, the material removal rate increases, becomes stable and then decreases
