The laser cutting process

Read Time:2 Minute, 51 Second

Laser cutting is a high-precision, high-speed thermal process for cutting various partially molten materials partially evaporated by the laser beam’s energy. High-pressure gas assists the cutting process, drawing the molten material from the cutting groove.

Some of the advantages of laser cutting are as follows:

  • No mechanical contact with the material
  • Automated processes
  • Minor cutting groove (0.1-0.5 mm) due to the location of the beam
  • High cutting speeds
  • You can achieve sharp angles and fine detail due to the reduced heat-affected zone in the material
  • You can cut a wide variety of materials regardless of their hardness
  • No tooling is required; only digital drawings

Some of the negative aspects of this process are:

  • The cost of laser cutting equipment is very high compared to other material cutting technologies.
  • The cut’s quality is optimal in thicknesses around 15-20 mm. For greater thicknesses, the rate of the amount drops considerably. (for these cases, water jet cutting can be used)

Description of the cutting process

A laser cutting equipment is generally composed of a resonator (which produces the laser radiation), and an automated positioning system that moves to achieve the desired cutting geometry (the head, the material, or a mixture of both can be moved).

The laser beam is focused on or below the material’s surface by a lens inside the cutting head. This focusing of the shaft causes a high concentration of energy that heats a material cylinder, melting and evaporating part of it. The removal of molten material is achieved by a gas flow coaxial with the laser beam. The relative movement between the laser beam and the material produces the cutting groove. The assistance gas fulfills the following functions in the cutting process:

  • Removes molten and evaporated material from the cutting area
  • The use of inert gas protects the cutting edge from oxidation.
  • The use of reactive gas increases the efficiency of the process.
  • Eliminates the plasma that can form in the cutting area, helping to improve the absorption of energy in the material

The laser cutting process is very complex, and many variables influence the results of the cut; however, the main factors to consider are:

  • Feed rate (lower as the thickness of the cut increases)
  • Cutting power
  • Focusing lens (depending on the thickness and type of material)
  • Focal point position
  • Assist gas (kind of gas and pressure)

The type of material has a determining influence on the absorption of laser energy. The maximum thickness that can be cut and the speed of the process will depend on this factor. Materials that can be laser cut include plastics, wood, rubber, fabrics, leather, carbon steel, stainless steel, aluminum, titanium, copper, bronze, etc.
