Match Li st- I ( Machining processes) w i th List-II (Operating Media)...
To match the machining processes (List-I) with the operating media (List-II), we need to understand the characteristics of each process and the media used in them. Let's look at each option in List-I and analyze the corresponding operating media in List-II.
List-I:
A. Abrasive jet machining
B. Electron beam machining
C. Electrochemical machining
D. Electro-discharge machining
List-II:
1. Dielectric
2. Electrolyte
3. Abrasive slurry
4. Vacuum
5. Air
Now, let's match each machining process with its appropriate operating media:
1. Abrasive jet machining: In this process, a high-velocity jet of abrasive particles is used to remove material from the workpiece. The abrasive particles are carried by a stream of fluid, which is typically air or water. Therefore, the operating media for abrasive jet machining is air.
2. Electron beam machining: This process uses a high-velocity electron beam to remove material from the workpiece. Since it is a non-contact process, there is no need for any operating media. Therefore, the operating media for electron beam machining is vacuum.
3. Electrochemical machining: In this process, material is removed from the workpiece by the electrochemical dissolution of the workpiece and the flow of electrolyte. The electrolyte is a conductive solution that facilitates the electrochemical reactions. Therefore, the operating media for electrochemical machining is an electrolyte.
4. Electro-discharge machining: This process uses electrical discharges to remove material from the workpiece. The material removal occurs in the presence of a dielectric medium, which is a non-conductive liquid or gas. The dielectric medium helps in controlling the spark formation and flushing away the debris. Therefore, the operating media for electro-discharge machining is a dielectric.
Based on the above analysis, the correct matching of machining processes (List-I) with the operating media (List-II) is:
A. Abrasive jet machining - 5 (Air)
B. Electron beam machining - 4 (Vacuum)
C. Electrochemical machining - 2 (Electrolyte)
D. Electro-discharge machining - 1 (Dielectric)
Therefore, the correct answer is option 'A' - 5 4 2 1.
