Correct cutting parameters are essential for achieving clean edges, stable output, and reliable cutting quality. In RDWorks, users can set key parameters such as output status, cutting speed, processing mode, minimum power, and maximum power before sending the file to the laser cutter.

This guide explains how to set cutting parameters in RDWorks V8 and shares practical tips for improving laser cutting results on different materials.

1. Basic Cutting Parameter Setup in RDWorks

Before starting a cutting job, select the target object in RDWorks and confirm that the output setting is enabled. This ensures the selected object will be included when the file is sent to the laser cutter.

1.1 Select the Target Object

First, select the object you want to cut. After selecting the object, check the layer settings and make sure “Output” is set to “Yes.” If output is not enabled, the selected design may not be processed by the machine.

1.2 Set the Cutting Speed

Cutting speed depends on the material type and thickness. Thicker or denser materials usually require a slower speed, while thinner materials can often be cut faster.

For most laser cutting machines, the maximum cutting speed is generally around 300 mm/s. Although a faster speed may be entered in the software, it may not significantly reduce cutting time and can reduce cutting quality.

1.3 Choose Cutting Mode

For the processing mode, select “Cutting.” This tells RDWorks that the selected object should be processed as a cutting path rather than engraving or scanning.

1.4 Set Minimum and Maximum Power

For better cutting quality, the minimum power should typically be set slightly lower than the maximum power. This helps the laser handle changes in speed more smoothly, especially when the laser head slows down at corners or curves.

When the laser makes a turn, the movement speed decreases. If the power remains too high at these slower points, the material may receive too much heat. Lowering the minimum power, often referred to as corner power, can help reduce burning, melting, or reflection-related damage at turns.

1.5 Confirm and Send the File

After setting the output status, cutting speed, cutting mode, minimum power, and maximum power, click “OK” to confirm the settings. Then send the file to your laser cutter and check the job before starting the cut.

3. Common Cutting Tips

Beyond software settings, cutting quality also depends on airflow, material behavior, and the way heat affects the cutting edge. The following tips can help improve cutting results.

3.1 Enable Auxiliary Air Assist

Air assist helps when cutting thicker materials and can reduce charring when cutting wood. By blowing air into the cutting area, it helps remove smoke and heat, resulting in cleaner edges.

If you frequently cut thick wood, adding an air compressor may significantly improve cutting efficiency and edge quality.

3.2 Cutting Acrylic

When cutting acrylic, use the slowest practical speed for smoother edges. A slower speed can help create a cleaner, more polished-looking cut surface.

4. Final Thoughts

Setting cutting parameters in RDWorks is a key step in preparing a laser cutting job. By selecting the correct object, enabling output, choosing cutting mode, setting speed, and adjusting minimum and maximum power, you can create a more stable and predictable cutting workflow.

For better results, combine correct RDWorks settings with proper material preparation, air assist, focus adjustment, and test cuts. These steps can help reduce charring, improve edge quality, and make your laser cutting process more efficient.
