Everything you need to know about sheet metal and laser cutting tech

In the manufacturing sector, the technological shift and advancement happen daily and producers look on innovative ways of how to minimize input and maximize profitability. What is I told you the chassis of your dream car was produced using heated laser rays, would you believe me, probably not?

As wild as it may seem, lasers are normally used to work, shape and mold sheet metal parts with a high degree of precision and accuracy. Laser tech is used to cut through thick metals as well as diamonds.

This laser tech is used in printers, scanners, internet signals, and telecommunication signals. Inlay man’s term; the science behind it is the increasing temperatures of the light rays till it cuts through the sheet metal.

For this post, we are going to have a brief discussion about the role of laser tech in sheet metal formation. 

Application of laser technology in sheet metal 

In sheet metal, lasers play a crucial role in most sectors. The super-hot light beams can vaporize, cut and melt a wide range of metals, it can also be used as a precision and accuracy tool as it allows the operator to monitor/control the intensity of the cutting as well as the depth.

Laser technology is all about thermal control by focusing the light beam and manipulating it to do whatever you want. One of the most widely used applications of lasers on sheet metals in the engraving of words or numbers.

The science of laser cutting tech

Laser cutting on sheet metal involves using the CAD systems for the manipulation of a six-axis robot or six-axis-flat-bed when cutting. The entirety of the whole process is autonomous and requires little personnel input.

The accuracy and precision of the lasers are pretty amazing but the calculations require can be a bit tricky even for the most experienced designers and engineers. 

Laser technology is not complex, a laser cutting machine; a source is used in the projection of a beam from a resonator via a beam path. The beam is in turn projected as a highly intense light on a single wavelength.

Through the use of benders, the beam bounces off different directions; the benders comprise of mirrors arranged in series such that the lasers become visible as well as handling projection of the temperature. 

As the laser passes through benders, it focuses more on the sheet metal that’s worked on. Before it reaches the sheet metal, the focused beam passes through a nozzle; the delivery of the beams is done through compressed gas. 

Most manufacturers opt for oxygen while others prefer nitrogen depending on their production needs and preference. As the beam flows through the nozzle, the laser cuts, and melts metals.

Curved mirrors can also be used to enhance the focusing of the beams by positioning these mirrors in the cutting head. Note that this is only done on a small scale with limited production details. 

The production industry continues to grow and develop daily, the only way of keeping up with the ever-changing trends in technology is by being innovative and creative and there is no better way of doing that by employing laser technology on sheet metal manufacturing.
