The metal removal rate in abrasive jet machining process is
- A. high
- B. very high
- C. low
- D. very low
Answer: C. low
Explanation: In Abrasive Jet Machining (AJM), the metal removal rate is very low (around $0.0001~cm^{3}/sec$). It is mostly used for finishing or cutting hard/brittle materials. Stray cutting cannot be avoided, tapering effects may occur, and soft materials cannot be machined effectively by this process.
