How to 3D Engrave Wood with a CNC Machine

A CNC machine is a computer-controlled router that can be used to create intricate designs in wood. When it comes to engraving, a CNC machine offers many advantages over traditional methods such as hand-held routers or laser engravers. First, CNC machines are much more precise, so your design looks clean and professional. Second, CNC machines can engrave much deeper into the wood than other methods so that you can create three-dimensional (3D) designs. Finally, CNC machines are relatively easy to use once you get the hang of them, so you’ll be able to produce beautiful engravings without much practice.

How to Set Up Your CNC Machine

The first step in using your CNC machine to engrave wood is setting up the machine. Most CNC machines come with detailed instructions on how to do this, so consult your owner’s manual for specific instructions on setting up and operating your particular model. In general, however, the setup process will involve connecting the machine to a power source and your computer, which will be used to control the machine. Once the machine is set up and powered, it’s time to start creating your design.

Designing Your Engraving

There are two ways to create a design for your engraving: either create one from scratch using a computer-aided design (CAD) program or modify an existing image file. If you’re starting from scratch, there are many different CAD programs that you can use; Autodesk’s Fusion 360 is a popular option that’s free for hobbyists and small businesses. If modifying an existing image file, you’ll need to convert it into a format your CNC machine can read; most machines can read common image formats such as .jpg or .png files. Once you have your design ready, it’s time to start engraving!

Engraving Your Design

When you’re ready to start engraving, load your desired material—in this case, wood—into the bed of your CNC machine. Then load your design file into the software that came with your machine; this software will be used to control the movements of the machine while it’s engraving. Once your design file is loaded, select the appropriate settings for depth, speed, and direction of travel; again, consult your owner’s manual for specific guidance on these settings. When you’re ready, hit the “start” button and watch as your CNC machine brings your design to life!


A CNC machine offers many advantages over traditional engraving methods such as hand-held routers or laser engravers. With a little practice, anyone can produce beautiful 3D designs in wood using a CNC machine.
