Brilliant 5 Benefits of Sheet Metal Fabrication

Laser Cutters are great tools proposing the possibility to create many different things like laser cut in Melbourne is its one of the major tasks. Starting from engraving simple boxes to detailed graphics into wood or constructing complex three-dimensional objects. Laser cutting technique uses a large amount of energy produced by a laser, focused on a very small rea, to cut or engrave a material. There is a wide range of materials that can be cut with a laser cutting machine like plastic, wood, textile, cardboard etc. Laser cutting works by supervising the output of a high-power laser with the help of optics. They oversee the laser beam generated on a small area of the material. The material then burns, melts, vaporizes away, or is blown away leave behind an edge with a good quality surface finish. Depending upon the type of laser it can cut until a 20mm-thick material. There are many other factors that change cut quality as well, but when everything is controlled properly, laser cutting is a stable, accurate, and very reliable cutting process. The laser cutter is one of the most useful tools in a modern-day. When the resonator produces lasers, mirrors handle the beam in the expected direction and lenses focus it at the required point. The crystal or the gas helps giving a more accurate and detailed direction and amplifying the laser beam. The focusing also magnifies its cutting power. Most laser-cutters utilize capacitive height control to maintain a correct gap between the workpiece and the nozzle-end, which is the leaving point for the laser beam. This gap will decide the cut quality. Compressed gases such as oxygen and nitrogen withdrawal as well from the nozzle-end and rinse the molten debris off the kerf.

In this beginners’ guide, we will explain the basics of how a laser cutter in almost companies in Melbourne works.

 

Sheet Metal Fabrication

Part 1: Designing the Running File

  • Decide the material you want to cut/ engrave as well as choose an image. Laser cutters can cut and engrave plastic, foam, wood, cardboard, fabric, and thin sheets of metal. Material containing chlorine cannot be used because of the toxic fumes they produce. Apart from this Avoid vinyl, PVC, and printed circuit boards. Glass can also be engraved but it cannot be cut as well as the thick metal cannot be cut. You must choose an image to cut/ engrave onto your selected material which can be a computer drawing, a photo, or computer text. At Accu Group you will provide us the these mentioned details and leave all other concern aside we will be doing other part for you.

Part 2: Setting up the Machine

  • We will upload the image into software that is compatible with our laser cutter (although the details about which software to use are mentioned on the side of the laser cutter – in case of any doubt we can check that). We save the image file to our computer. After that we open that software (popular software that we usually use is corelDraw, Auto CAD, and Adobe illustrator).
  • We set the dimensions of your image to match up the size of our material. It is very important that the size of the image is not larger than the size of our material, otherwise we will end up with some sections of the image missing in the final material. Using the mentioned software, we change the dimensions to match the size of your material. For example, if our material is 10 centimetres (3.9 in) x 20 centimetres (7.9 in) then we enter 10 centimetres (3.9 in) as the width and 20 centimetres (7.9 in) as the height. The important thing that we usually keep in mind here is that we have selected the correct unit of measurement. Now everything related to the material and design is done.
  • Turn on the laser cutter and place the material in the middle of the laser cutting mat. This is the ideal location to achieve a quality result. If material does not fit, we need to trim it down so it can fit inside the machine without turning up at the sides. Laser then tests its dimensions across the mat. We need to resize your image if we trim the material. If the material has a bend in it, we usually place a weighty metal rod on the ends of the material to hold it down.
  • Clean the lens with rubbing alcohol or any other material which remain soft on the lens. Damp a piece of cotton wool with rubbing alcohol and gently rub the lens of the laser cutter. We can follow the process of cleaning lens even if it is still in the machine.
  • We then focus the laser by modifying (if required) the height of the cutting table using the control panel. Changing the height of the cutting table in such a way so that the tip of the focus pin just touches the top surface of the material.
  • After adjusting the height, we press on the switch of the fume extractor. This is the large tube located at the back of the laser cutter. The fume extractor extracts all the fumes and dust from the material out of the laser cutting machine. We do not use any materials that include chloride, even if we are using a fume extractor.
  • At the end of the all the mentioned steps we choose some print settings on the machines like mentioning the material type and select the type of cuts we are making. When we click on the print menu a preferences menu will pop up and will ask us to choose the cutting method like raster or vector. Vector print is used in case we are cutting images and if we are engraving anything then we need to select the vector print.

 

The most important step of the laser cutting machine that we always do is to clean up the scrap so that machine can be used again for some other customer who visits ACCU GROUP for engraving or for laser cuts in Melbourne. This is how we perform the laser cutting in ACCU GROUP. Although outsourcing companies usually don’t share their process of cutting or performing any other activity but we ACCU GROUP as an outsourcing company want to be transparent enough with our customers so that they believe us and trust our way of working.
