It has been widely used in industrial production. However, safety issues during operations have increasingly attracted people’s attention. The operation of laser cutting machines involves high-energy laser beams and complex mechanical systems. If appropriate safety measures are not taken, it may cause serious harm to operators and equipment, or even cause accidents. Therefore, when operating a laser cutting machine, a series of strict safety measures must be taken to ensure the safety of operators and equipment.

This article will introduce in detail the various safety measures that should be taken when operating a laser cutting machine, including the basic principles of laser cutting machines, the importance of operating laser cutting machines safely, and the development trends and application fields of laser cutting technology to ensure the safety of operations.

Basic principles of laser cutting machine

A laser cutting machine is a device that uses a high-energy laser beam to cut materials into desired shapes. Its basic principle involves the following key steps:

Laser transmitter generates laser beams: Laser cutting machines usually use CO2 laser generators or fiber laser generators as laser sources to generate high-energy laser beams by exciting working materials, such as gas or optical fibers.
Focusing of the laser beam: The generated laser beam is focused through optical elements, such as concave lenses or optical fibers. The focused laser beam can concentrate energy in a very small area, increasing cutting accuracy and efficiency.
Material absorbs laser energy: When the laser beam is focused on the surface of the workpiece, it is absorbed by the cutting material and converted into heat energy. The energy of a high-energy laser beam causes the material to locally heat up, causing it to melt or vaporize.
Assist gas to clear the melted area: Use an assist gas, such as nitrogen or oxygen, to purge the molten material and help cool the cutting area. Different assist gases can affect cutting quality and speed.
The control system controls the cutting process: The control system can precisely control the intensity, focus position, and movement path of the laser beam. The operator can input the designed cutting pattern to make the machine cut according to the predetermined path.

Therefore, the laser cutting machine uses laser beam to locally heat and melt or vaporize the material, and then achieves precise cutting of the material by moving the laser beam and supplemented by auxiliary gas purge. This cutting method is efficient, precise, and suitable for a variety of materials, but improper operation can also cause serious injuries. The safe operation of laser-cutting machines is crucial to operators and equipment.
