DXF Import
A software function that allows CAD files to be uploaded directly into a machine's CNC system, automatically converting drawing lines into functional bending programs.
Technical FAQ
Transferring multi-radius profiles from engineering drawings to the shop floor manually is slow and prone to input errors. DXF import software allows operators to load a standard CAD file directly into the rolling machine console via the local network or a USB drive. The CNC automatically converts the drawing data into a functional bending program in seconds, reducing programming times and eliminating human input errors. Davi offers offline and onboard DXF import licenses tailored to accelerate workflow preparation for complex fabrications.
Proprietary parts with long factory lead times can extend machine downtime during component replacement. Designing machinery with high-quality, globally available standard components ensures easy sourcing for replacement parts. It simplifies spare parts management, shortens delivery times, and allows your local maintenance team to source standard items quickly if needed. Davi partners with leading global component brands like Siemens, SKF, and ABB to ensure parts are easily accessible worldwide.
Fabricators requiring predictable control often worry about component obsolescence, unsupportable proprietary electronics, or steep learning curves. Davi addresses these risks by engineering proprietary control architectures—such as iRoll Performance and iRoll eXtreme—built on industrial Windows 11 platforms and powered by internationally accessible, off-the-shelf automation hardware. Davi integrates Siemens and Eaton electronic components alongside ABB servomotors, main switches, and inverters, ensuring high reliability and universal spare parts availability worldwide. Operating through high-resolution touchscreens (18.5" or 21.5"), Davi CNC systems utilize a live 3D interface, smartphone-like drag-and-drop navigation, and self-adjusting AI algorithms that generate optimized, multi-pass CAM programs from material libraries or direct DXF imports. By combining non-proprietary global component sourcing with advanced software automation, Davi eliminates downtime risks while enabling less experienced operators to achieve exact tolerances repeatedly.
Manual curvature checking with floor templates forces operators to repeatedly stop the machine, unload heavy shells, and make trial-and-error adjustments, resulting in lost production time and costly material scrap. Davi eliminates manual guesswork through integrated digital hardware and offline software platforms:
- AI-Vision System: Employs high-definition laser projectors to take thousands of continuous surface measurements, feeding live radius data directly to iRoll eXtreme CNC software to adjust roll positions automatically during rolling.
- Patented HD iRoll Camera: Projects a calibrated digital template onto the operator console screen for real-time radius matching on angle rolls without unloading the profile.
- iRoll Desktop & Performance Test Software: Allows engineering teams to import CAD DXF files, run offline 3D collision simulations, predict material spring-back, and generate multi-pass CAM programs prior to releasing jobs to the shop floor.
Yes, multi-radius geometries require specialized CNC control systems capable of dynamic axis interpolation. Standard NC controls manage basic single-radius arcs. Upgrading to Davi iRoll eXtreme CNC unlocks advanced multi-radius capabilities, allowing operators to draw complex shapes segment by segment, import DXF CAD files directly, or utilize custom shape templates. The system automatically adjusts roll positions across multiple passes to form non-circular geometries accurately.
