Introduction to laser cutting process:
Laser which stands for Light amplification by stimulated emission of radiation.When electromagnetic radiation or some times visible radiations released by the stimulated emission then this is known as Lasers.Electrons present in the elements can change their state in order to attain stability.When any energy is supplied then electrons are excited to higher states,but at the higher states these are not so stable so it jumps down by releasing some energy.These energy comes under certain range .It can be in the electromagnetic range,visible range or may be in some other range of the spectrum.Laser is a monochromatic and short wavelength rays.These rays have high frequency. Is this topic Definition Kinetic Energy hard for you? Watch out for my coming posts.
Laser beams are very useful in many fields.Laser cutting is also a field where lasers are used to cut the materials.Lasers are very high power beams when it is subjected to the materials then material melts,vaporises or burns,or it is blown away by the high pressure beams.As compared to the mechanical cutting this process of cutting is very effective and accurate.Some times materials are very hard to cut by using normal mechanical methods,so in these cases laser cutting helps and it makes the cutting very easy and simple.
Types of Laser
There are mainly three types of laser cutting device is used depending upon the material used for the production of lasers.These materials are.
1)Carbon Dioxide
2)Neodymium
3)Neodymium yttrium Aluminium garnet
These different lasers are used in different applications.These are used for cutting,trimming,scribing.engraving etc.To produce the laser beams the lasing materials are stimulated ,then the generated beam is reflected so many times internally by using mirrors till it gains high energy to come out as monochromatic beams.
Different Methods of Cutting by Laser
By using laser cutting of material can be done in various ways.The high energy of the beam is mainly used to cut the material.Some of the methods are described below
By vaporising-in this method the material is heated to its boiling point to obtain a gap.
Thermal stress cutting-This method is used for the brittle material .When Brittle material is subjected to high heat then it results in crack.
melt and blow-In this method first the material is melt and then it is blown by high pressure beams.
By cold cutting
Scribing
