5/11/2024: How to Cut Acrylic on Your CNC - Tips, Tricks, and New Product Highlights for Sydney Nomads!

If you've ever found cutting acrylic with your CNC machine challenging, you're not alone. Many makers and DIY enthusiasts in Sydney and beyond aim to create stunning projects with this versatile material. Today, we’ll explore essential tips for cutting acrylic safely and effectively with your CNC machine. We will also highlight some exciting new products from Nomad CNC and share strategies to successfully market your creations in your local area.

Understanding Acrylic and Its Properties

Before starting your project, it's crucial to understand acrylic. This material, known for its glass-like appearance, comes in two main types: cast and extruded. Cast acrylic is typically easier to cut and has a clearer finish, making it the preferred choice for projects such as trophies and signs. For instance, cast acrylic boasts a transparency of about 92%, compared to 87% for extruded acrylic.

While working with acrylic can be rewarding, it’s important to be aware that it is more brittle than materials like wood or metal. Without proper handling, it can crack or chip during the cutting process. Always ensure your workspace is set up to minimize the risk of damaging the sheets while positioning and securing them.

Selecting the Right Tool Bits

Choosing the right tool bit is essential for quality results when cutting acrylic. Opt for a single-flute or up-cut spiral bit. These bits effectively remove chips and prevent melting during cutting.

Recommended Tool Bits:

• 1/8" Single-Flute Up-Cut Spiral Bit: Ideal for detailed work, such as intricate designs and small projects.

  
  

• 1/4" Up-Cut Spiral Bit: Suitable for larger cuts, this bit allows faster feed rates, enhancing productivity for bigger sheets.

  
  

Make sure to keep your bits sharp! Dull bits can lead to jagged edges and inconsistent cuts, which can ruin your final product. Regular maintenance of your bits can increase their lifespan by up to 50%, ensuring smoother operation.

Feeds and Speeds: Get It Right

Understanding feeds and speeds is crucial for successful acrylic cutting. Each machine has different capabilities, so perform some trials to determine what works best.

Key Definitions:

• Feed Rate: The speed at which the material moves into the cutting bit. For cutting acrylic, a good starting range is 60-120 inches per minute (IPM), depending on material thickness.

  
  

• Spindle Speed: This refers to the number of rotations per minute (RPM) of the cutting tool. For optimal cutting of acrylic, aim for a range of 10,000 to 20,000 RPM.

  
  

Best Practices:

1. Start Slow: If you are new to cutting acrylic, begin with lower speeds and feeds. This helps you gain confidence and understand how the material behaves.

   
   

2. Incremental Adjustments: After testing lower settings, gradually increase the feed rate and spindle speed to find a balance that prevents chipping or melting.

   
   

3. Take Breaks: When cutting large pieces, allow your CNC machine to cool down, particularly in hot environments. Overheating can lead not only to melting but also wear on your machine.

   
   

Cutting Techniques to Avoid Melting

Acrylic has a tendency to melt if the cutting bit generates excessive heat. Here are some techniques to help ensure clean cuts:

• Air Assist: Use an air assist feature on your CNC machine. It helps cool the acrylic and clears away chips, greatly reducing the chances of melting. Studies show that using air assist can increase cut quality by up to 30%.

  
  

• Depth of Cut: Making shallower cuts can be more manageable when working with acrylic. Consider making multiple passes instead of cutting through the entire material at once. This reduces pressure on the acrylic, preserving its clarity and finish.
