DXF stores 2D and 3D geometry in a text or binary structure, making it ideal for CNC machining and laser cutting workflows. DXF files contain vector-based data such as lines, arcs, and polylines, which define precise tool paths for cutting operations.
In cutting tool data exchange, DXF is often used alongside ISO 13399-compliant datasets to provide accurate geometry for tool assemblies. While DXF ensures universal compatibility, it lacks rich metadata like material properties or tool classification, which are handled by standards such as ISO 13399. Proper preparation of DXF files — removing redundant elements, ensuring correct scaling, and validating layers — is essential to avoid errors during CNC programming.
