How Does a CNC Woodworking Machine Work?

CNC woodworking machines are highly efficient tools that operate based on a set of instructions known as G-code. This programming language dictates how the machine’s cutting tools move in three dimensions and control other important functions. Woodworkers begin the process by creating a digital design using CAD software, which is then imported into CAM software to generate tool-paths.

The tool-paths serve as a map for the CNC machine, providing precise instructions for the movements of the cutting tools to achieve the desired shapes and cuts. To make these tool-paths machine-readable, they are converted into machine-specific G-code using post-processing software.

Once the G-code is prepared, it is transferred to the CNC woodworking machine, where the machine’s controller reads and executes the instructions. The machine’s motorized axes play a crucial role in positioning the cutting tools with remarkable accuracy, allowing for complex shapes and intricate details to be achieved.

Here is an example of a G-code instruction:
