Want to Cut Domes with a CNC Plasma Machine? Here’s What You Need to Know

Cutting domes can be tricky, especially if you’re new to it. Whether you already have an AKS Cutting Systems robotic plasma cutter or you’re still weighing your options, this guide will help you get started on the right foot.

Our CNC plasma tables are designed to handle complex shapes like domes. However, getting clean, accurate cuts depends on a few key setup choices. With the right approach, you’ll be in a good spot to get consistent results that meet your specifications.

Choose the Right Plasma Consumable and Equipment Combination

Cutting a quality dome starts with the right equipment. First, you’ll need to choose a plasma cutting table that’s suitable for your needs. One of the biggest considerations is the thickness of the metal you’re cutting. A robotic plasma cutter with a high amperage rating will cut through thicker metal, while one with a lower amperage rating will be better suited for thinner material.

Along with the table, you’ll need to evaluate which consumable is right for your needs. The consumable is the part of the torch that shapes and directs the plasma arc. These components wear out over time and must be matched to the machine’s amperage and the material you’re cutting.

Choosing the right equipment and consumable combination can be difficult. That’s why we make it easy. If you have questions about what’s best for you, just take a look at any of our plasma cutter pages. You’ll find a section entitled “power and gas options” that’s designed to help you make the right decision. Just choose a power supply, then a gas console, and our website will automatically tell you what that combination can handle.


Create a Detailed Design

Once you’ve chosen your equipment, it’s time to create a detailed design. You must include precise measurements and specifications, including the radius, height, and thickness of the metal.

It’s also important to factor in the type of metal, as different materials conduct heat differently. For example, you may have to adjust your cutting speed and amperage for stainless steel versus mild steel.

Set Proper Cutting Parameters

Once you’ve selected the robotic plasma cutter and finalized the design, you must set the proper cutting parameters. These include the cutting speed, amperage, and torch height. The cutting speed should be set to match the thickness of the metal, while the amperage and torch height should be adjusted to optimize the cut quality.

Take Advantage of the Automatic Torch Height Control

An AKS Cutting Systems CNC plasma table features automatic torch height control technology. This equipment automatically maintains the proper height of the torch, keeping it at a constant distance from the metal. It helps ensure a precise and accurate cut and reduces the risk of warping or distortion.

Monitor the Cut

As the dome is being cut, it’s important to monitor its progress. This includes checking for any warping or distortion of the metal and making adjustments as necessary.

If you’re running into any issues with the quality of your cuts, you can always reach out to the AKS customer service team for assistance. Our U.S.-based team can answer any questions you have over the phone. And if we can’t troubleshoot it remotely, we can send a technician out to take a look.
