Bulk metal removal processes are used to remove a large amount of material from a workpiece to achieve the desired shape or size. These processes are typically used in manufacturing industries to create components with complex shapes or to remove excess material from a workpiece.
The options provided are ECM (Electrochemical Machining), EDM (Electrical Discharge Machining), EBM (Electron Beam Machining), and LBM (Laser Beam Machining). Let's discuss each option to determine which one is not a bulk metal removal process.
1. ECM (Electrochemical Machining):
- ECM is a non-traditional machining process that uses the principles of electrochemistry to remove material from a workpiece.
- In ECM, a high current is applied between the workpiece and the tool, which is immersed in an electrolyte solution.
- The material is removed from the workpiece through a combination of electrochemical dissolution and mechanical erosion.
- ECM is capable of removing a large amount of material from a workpiece and is therefore considered a bulk metal removal process.
2. EDM (Electrical Discharge Machining):
- EDM is a non-traditional machining process that uses electrical energy to remove material from a workpiece.
- In EDM, a high-frequency electrical discharge is generated between the workpiece and the tool, which is usually a wire or an electrode.
- The electrical discharge melts and vaporizes the material, creating a small crater on the workpiece.
- EDM is commonly used for machining hard and brittle materials and is capable of removing a large amount of material, making it a bulk metal removal process.
3. EBM (Electron Beam Machining):
- EBM is a non-traditional machining process that uses a high-velocity electron beam to remove material from a workpiece.
- In EBM, a focused electron beam is directed onto the workpiece, causing the material to melt and vaporize.
- The high energy of the electron beam allows for precise and controlled material removal.
- EBM is capable of removing a large amount of material and is therefore considered a bulk metal removal process.
4. LBM (Laser Beam Machining):
- LBM is a non-traditional machining process that uses a high-intensity laser beam to remove material from a workpiece.
- In LBM, the laser beam is focused onto the workpiece, causing the material to melt, vaporize, or be blown away by a jet of gas.
- LBM is commonly used for cutting, drilling, and welding operations and is capable of removing a large amount of material, making it a bulk metal removal process.
From the above explanations, it can be concluded that option 3 (EBM) and option 4 (LBM) are both bulk metal removal processes. Therefore, the correct answer is option A (3 and 4).

From the above explanations, it can be concluded that option 3 (EBM) and option 4 (LBM) are both bulk metal removal processes. Therefore, the correct answer is option A (3 and 4).
