Advantages of Laser Beam Machining
- In the Laser beam Machining (LBM) process there is no direct contact between the tool and the workpiece, hence there is no issue of tool wear.
- Machining can be done in any environment.
- Refractory materials can be easily worked.
- Easy machining of brittle, non-metallic, and hard materials.
- Used for welding of dissimilar metals.
- Extremely small holes can be drilled easily.
Disadvantages of Laser Beam Machining
- LBM is applicable only for thin sections and where a small quantity of material is removed.
- Control of hole size is difficult.
- Holes drilled may have a slight taper formation, hence not suitable for large holes.
- The durability and reliability of the system are limited.
- Due to the low production rate, the efficiency of the system is low.
- The initial cost and operating cost of the system are high.
- Highly skilled operators are required.
Applications of Laser Beam Machining
- LBM is used for the trimming of sheet metal, carbon resistors, and plastic parts.
- It is used for drilling small holes in the materials like tungsten, ceramics which are very hard.
- LBM is also suitable for dynamic balancing of precise rotating components lie watches.
- Cutting complicated profiles on thin films for making Integrated Circuits, engraving patterns on suitable thin films or sheets.
