Laser Cutting Working Principle

A laser differs from other sources of light in that it emits light which is coherent.

Laser cutting working principle.

Laser cutting uses the laser beam as the heat source for hot cutting its working principle is similar to laser welding. The laser optics and cnc computer numerical control are used to direct the material or the laser beam generated. Laser principles of working of a laser. The principle of laser cutting laser cutting is a thermal separation process.

Laser cutting works by directing the output of a high power laser most commonly through optics. Spatial coherence allows a laser to be focused to a tight spot enabling applications such as laser cutting and lithography. Http www wissensfloater de arrangement physical requirements laser melt cutting laser flame cutting contours and bevel cuts punching of holes compari. This paper shows every parts of the fiber laser cutting machine how to operate the fiber laser marking machine how to maintain it etc.

In lasers photons are interacted in three ways with the atoms. 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 temperature of laser cutting exceed 11000 which would have made any material gasification therefore gasification also plays an important role in addition to the melting during laser cutting process. Yag and fiber lasers permit a controlled heat entry which is optimum for fine cutting.
