Design Considerations for Stainless Steel Laser Cutting

With a Canberra laser cut stainless steel service readily available, you can turn a sheet of stainless steel into a creative or decorative piece. But there are some design guidelines you need to understand if you want the best results.

Even the best laser cutting machine has its limitations. This is why it is best to work with the equipment’s strengths to get the design you want with accuracy and precision, preferably at 100%.

What You Need to Know About the Stainless Steel Material to Use

  1. How thick or thin a material is may not matter anymore.

Advancements in technology ensure that an 8-kW solid-state laser can cut 0.039-in.-thick steel quickly and without compromising the end product. Still, it is recommended that you refer to providers of laser cut stainless steel in Canberra for more information.

  1. Laser beams can change stainless steel.

The use of a high-intensity light source can melt metal in milliseconds, resulting in a heat-affected zone (HAZ) along the edge where the cut is made. For certain industries, such as aeronautics, HAZ and microfissures can be a problem. However, if your design will not be used in aviation, then HAZ will be a non-issue.

  1. Tapering may be more noticeable in thick stainless steel.

Because the focused laser beam is shaped like an hourglass rather than a straight line, tapering may occur. It’s a non-issue for thin stainless steel but may be noticeable in materials that are 0.50 inch thick and thicker. But if you find best laser cut stainless steel in Canberra, you will be able to work with fabricators who can eliminate or minimise tapering. For more information, visit us at Metal 4 U.

  1. There are limitations to laser-cut parts.

Although the laser cut stainless steel Canberra offers can create just about any shape you desire, issues may arise with tiny cuts as improper bend relief may happen. Laser cutting uses an assist gas that usually travels on the path of least resistance, while the laser travels on the opposite side. This causes the dross forming on the relief edge not to be ejected properly and get in the way of the bend.

  1. The type of assist gas used may affect the cutting speed.

Shielding gas, usually oxygen or nitrogen, is used around the cutting nozzle to blow molten metal away. The former enhances the cutting speed, while the latter does the opposite.

Now that you know more about stainless steel and laser cutting, you should take these pointers into consideration when creating your design for Canberra laser cut stainless steel.

Design Guidelines to Keep in Mind

  • Never leave a path open because the laser won’t be able to close it and cut accordingly. An object should be an entire piece, with no cuts in between.
  • Always create a design that allows stainless steel to be processed at really high temperatures.
  • Avoid designing too small holes to prevent issues on bend relief. Learn about the acceptable diameter for a specific stainless steel thickness. A hole with a minimum of 2.5 mm diameter is suitable for stainless steel that is 1 mm thick.
  • Avoid too thin lines as minor deformations due to the laser’s heat may occur.

Because design guidelines vary from one provider of Canberra laser cut stainless steel to another, it is best to speak to an expert or specialist.
