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. </skos:scopeNote><skos:inScheme rdf:resource="http://AATesaurus.cultura.gencat.cat/aat/getty_en"/><skos:related rdf:resource="http://AATesaurus.cultura.gencat.cat/aat/getty_en?tema=31353677"/><skos:broader rdf:resource="http://AATesaurus.cultura.gencat.cat/aat/getty_en?tema=31298694"/><skos:exactMatch> <skos:Concept rdf:about="http://AATesaurus.cultura.gencat.cat/aat/getty_es/index.php?tema=14053849"> <skos:prefLabel xml:lang="es">computer numerical control machining (traducció pendent)</skos:prefLabel> </skos:Concept></skos:exactMatch><skos:exactMatch> <skos:Concept rdf:about="http://AATesaurus.cultura.gencat.cat/aat/getty_ca/index.php?tema=9823928"> <skos:prefLabel xml:lang="ca">computer numerical control machining (traducció pendent)</skos:prefLabel> </skos:Concept></skos:exactMatch>  <dct:created>2026-03-30 20:22:03</dct:created>  </skos:Concept></rdf:RDF>
