How do I “do” CNC?

CNC involves a “software tool chain.” This means that there is more than one program required to go from initial concept to the design being cut on your machine. The basic links of the chain are CAD -> CAM -> G Code Streaming.

First, the part is designed in CAD (Computer-Aided Design) software. Alternatively, you may find “flat files” such as those with extensions of “DXF” or “SVF” files on vector design websites, or sharing websites.

After the part is designed, a CAM (Computer-Aided Manufacturing) program is used to generate “G Code” for the part. G Code just tells your CNC machine how it is to move in order to cut out or engrave your part.

The G Code file is “streamed” from your computer to your UTECH CNC machine by USB disk.
