In today’s world of custom manufacturing and personalized products, 3D wood engraving has become a highly sought-after service. Whether it’s interior design, furniture accents, souvenirs, or artwork, 3D engraving gives products a unique value and aesthetic appeal. In this article, we will tell you about the process of creating a professional 3D engraving on a Wattsan CNC milling machine, helping you take the first steps towards turning your machine into a profitable tool.
Preparing the working file
Creating a functional file is the first and most important step in 3D engraving. We recommend using the ArtCAM software to perform this operation, as this reliable application allows users to configure all processing parameters and even view the finished product before production begins. When creating a layout, be especially attentive to:
- Dimensions: the dimensions of the model must match the dimensions of the actual workpiece.
- Detail: the level of detail of the final image is directly affected by the size of the field and the resolution of the image. Increasing or decreasing the image size without changing the details can significantly affect the quality of the engraving.
With proper configuration, an uninterrupted workflow and professional-quality results are guaranteed at this stage.
Setting up machining parameters
Once the model is ready, it’s time to set the processing parameters:
- Tool selection: select the appropriate cutting tool depending on the material and complexity of the construction. The contours must be carefully adjusted according to the characteristics and shapes of the model.
- Cutting depth: adjust the depth levels to ensure that the material is removed cleanly without overloading the spindle or milling cutter.
- Speed settings: change the spindle and feed speeds depending on the material and type of milling cutter.
Wattsan CNC milling machines can process wood, plastics, composite materials, soft metals and other materials. In this example, MDF will be used, which is ideal for 3D engraving due to its smooth texture and ease of processing.
Uploading and setting up the machine
After configuring the file, transfer it to the device’s DSP controller. Then:
- Set the starting point on the X and Y axes.
- For more accuracy, find the zero point on the Z axis manually or using a special Z-probe sensor.
Fine tuning ensures that the machine follows the programmed trajectories correctly, while maintaining consistency throughout the product.

It is recommended to use separate milling cutters for roughing and finishing to achieve maximum results and reduce tool and spindle wear.:
- Roughing pass: start by roughing with a straight end mill. This cutter will quickly remove the bulk of the material, making it easier to work on finer processing steps.
- Last pass: use a conical cutter with a rounded end for the last pass. To get a smooth surface and good detail resolution, set a small pitch value.
Performing these two steps separately not only prolongs the life of your tools, but also significantly improves the overall quality of your engraving.
Monitoring and finalizing
Start the machining process and monitor the machine operation in the initial stages to make sure everything is going smoothly. After completing the work, inspect the final product for surface quality and detail. With the right settings and attention to detail, professional-level craftsmanship can be achieved even in a tiny workshop, as evidenced by the clean, incredibly detailed 3D engraving resulting from the precise execution of these steps.
Conclusion
With proper execution and careful planning, 3D engraving on a Wattsan CNC milling machine is a simple but practical procedure. You can create professional-level engravings by becoming an expert in preparing files, selecting the right tools, and configuring processing parameters. It is wise to start with materials such as MDF, and as your abilities develop, you will be able to confidently work with hardwoods, plastics, and other complex materials. Whether you want to expand your business, start a new one, or just learn more about 3D machining, Wattsan CNC milling machines provide the reliability and performance needed to succeed.
