This would involve importing the DWG or DXF file into a CAM/CNC software to generate the G-code. The second step would typically entail converting the DWG or DXF file to G-code. Conversely, if the designer uses CAM software, then they would save the design using the DXF file format. If the drawing is created using CAD software, then it would be stored as a DWG file. Using it as a guide, they then create the design using CAD or CAM software. First, a designer sketches a freehand design on a piece of paper. When it comes to creating designs that are to be turned into actual objects through CNC machining, the process normally follows a few common steps. G-code, therefore, tells CNC machining tools the type of actions to undertake. On the other hand, G-code is any programming language/code that issues instructions to the CNC milling or machining tools. The idea behind its creation was in order to facilitate the exchange of data between Autodesk’s AutoCAD and other CAD or between CAD programs and downstream CAM/CAE programs.
