How Does Laser Beam Machining Work

The laser light is so high powered that when focused it raises the temperature of the material to be cut high enough to melt or vaporize the material in. But lasers play a pivotal role in our everyday lives too.

Laser Beam Machining

Laser cutting is a thermal separation method in which many different materials can be cut quickly precisely and without reworking.

How does laser beam machining work. The fact is they show up in an amazing range of products and technologies. Tattoo removal hair replacement eye surgery they all use lasers. It creates the beam through the machines beam path. Precision may be better since the laser beam does not wear during the process. A laser cutting machine works by focussing a beam of laser light onto a piece of material. When cutting stainless steel or aluminum the laser beam simply melts the material and high pressure nitrogen is used to blow the molten metal out of the kerf. The beam is only about 34 of an inch in diameter as it travels from the laser resonator. Advantages of laser cutting over mechanical cutting include easier workholding and reduced contamination of workpiece since there is no cutting edge which can become contaminated by the material or contaminate the material.

It is commonly used with materials like wood paper textiles. Laser beam machining lbm is a non conventional machining manufacturing process a form of machining in which a laser is directed towards the work piece for machining. Youll find them in everything from cd players to dental drills to high speed metal cutting machines to measuring systems. The focused laser beam goes through the bore of a nozzle right before it hits the plate. But what is a laser. This process uses thermal energy to remove material from metallic or nonmetallic surfaces.

On a cnc laser cutter the laser cutting head is moved over the metal plate in the shape of the desired part thus cutting the part out of the plate. Also flowing through that nozzle bore is a compressed gas such as oxygen or nitrogen.
