The basic process includes designing the CAD model, converting the CAD file to a CNC program, preparing the CNC machine, and executing the machining operation. It is suitable for a wide range of materials, including metals, plastics, wood, glass, foam, and composites, and encompasses different operations including mechanical, chemical, electrical, and thermal processes.  ]]></dc:description></metadata>
