How does laser beam machining work?
A laser beam machining is a non-traditional machining method in which the operation is performed by laser light. The laser light has a maximum temperature on the workpiece, causing the workpiece to melt due to the high speed. The process used thermal energy to remove material from a metal surface.
What is the advantage of laser beam machining?
The main advantages of laser beam machining are ease of automation for complex cutting patterns, absence of tool wear and breakage, ability to cut at shallow angles, and rapid cutting rates. As it is a noncontact process, energy transfer between the laser and the material occurs through irradiation.
Which laser is used in laser beam machining?
Types of lasers used for laser beam machining: Gas lasers such as CO2 and excimer lasers, along with solid-state lasers such as Nd:YAG and YAG lasers and femtosecond lasers, are some of the most popular lasers.
What are the applications of laser machining?
It is used in industry for producing holes in turbine blades, combustion chambers, and aerosol nozzles, among other applications. Laser cutting is used to produce intricate two-dimensional shapes in workpieces made out of materials such as sheet metal and paper up to 15mm thick with high cutting speeds.
What is laser beam machining explain its process applications advantages and disadvantages?
1 It can be used to cut aby material. 2) No tool cost because no physicla tool is required and hence no cost for mantenance and replacement of tools. 3) No delamination is caused as there is no physical contact with the workpiece. 4) It can be easily automated and is very flexible.
What are the characteristics of laser beam machining?
Laser beam have two great characteristics, these are monochromatic and parallel so it can be directly focused to a micron size diameter and can produce high energy (like 100MW) for micro size area. It is best for making a precise micro size hole. Also, it can be used for other micro machining on all types of materials.
What are the advantages and disadvantages of laser beam machining?
Advantages and Disadvantages:
- It can cut all material.
- No tooling cost because no physical tool is required.
- It produces finish part or high surface finish.
- No tool wear because no physical tool is used.
- Micro holes can be drilled accurately.
- Complex shape can be machined easily because laser can be move in any path.
How is machining time in laser beam machining?
Explanation: Time of machining in the laser beam machining process is directly proportional to laser beam spot diameter. Larger the diameter, larger will be the HAZ. Explanation: Laser beam machining is more versatile and can be used for the metal as well as non metal.
What are the characteristics of laser beam?
In Chapter 1 it was stated that the most characteristic properties of laser beams are (i) monochromaticity, (ii) coherence (spatial and temporal), (iii) directionality, (iv) brightness.
What is laser drilling used for?
Laser-drilled high-aspect-ratio holes are used in many applications, including the oil gallery of some engine blocks, aerospace turbine-engine cooling holes, laser fusion components, and printed circuit board micro-vias.
What is the importance of laser?
Laser technology is very important in the modern world because it is used in many fields, most notably measurement, where it is used to give high accuracy results in measuring small and large distances. Laser technology is also used for the purposes of generating heat in industrial cutting processes.
What is laser and its types?
Based on their gain medium, lasers are classified into five main types: Gas Lasers. Solid-State Lasers. Fiber Lasers. Liquid Lasers (Dye Lasers)
