Laser Beam Machining (LBM)

Laser Beam Machining (LBM) is a non-conventional machining process that involves the use of high-energy laser beams to remove material from the workpiece's surface. In this process, a focused laser beam is used to melt and vaporize the material, creating a cavity or a hole in the workpiece.

Ablation

Ablation is the process of removing material from the surface of a solid material by vaporization or melting. In LBM, ablation occurs due to the high-energy laser beam melting and vaporizing the material from the workpiece's surface.

Advantages of LBM

1. High precision: LBM offers high precision and accuracy in machining, making it ideal for producing complex and intricate shapes.

2. No tool wear: As there is no physical contact between the tool and the workpiece, there is no tool wear in LBM.

3. No heat-affected zone: Due to the high-energy laser beam, the material is melted and vaporized, leaving no heat-affected zone behind.

4. Non-contact process: LBM is a non-contact process, which means there is no physical contact between the tool and the workpiece, reducing the risk of damage to the workpiece.

Applications of LBM

1. Aerospace industry: LBM is used in the aerospace industry to manufacture complex and lightweight components.

2. Medical industry: LBM is used in the medical industry to produce intricate surgical instruments and implants.

3. Electronics industry: LBM is used in the electronics industry to produce microelectronic components.

4. Automotive industry: LBM is used in the automotive industry to manufacture engine components and other parts.
