Radius Correction
A real-time control adjustment made to a CNC program to compensate for variance in material batches or spring-back, ensuring the final workpiece matches design values.
Technical FAQ
Eliminating material waste and avoiding secondary cutting operations is a primary goal for high-productivity job shops looking to protect their margins. A flat end is the straight, unbent section left at the leading and trailing edges of a plate because the material cannot physically reach the exact tangent contact point between the machine rolls. Minimizing this straight section directly reduces material scrap and eliminates the time-consuming process of pre-bending plates on a separate press brake, thereby accelerating overall floor cycle times. Utilizing Davi all-rolls-drive technology ensures the plate can be positioned precisely at the tangent point to achieve the shortest flat end possible without compromising safety.
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.
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.
Davi provides advanced digital and optical measuring devices to replace manual physical templates:
- AI-Vision System: A laser measurement system projecting thousands of data points across the plate to read actual forming radii in real time without stopping the machine.
- Patented HD iRoll Camera: A digital camera system for angle rolls that projects a calibrated template directly onto the operator screen for instant radius verification.
- Automatic Radius & Circumference Measuring Tools: Electronic measuring arms that log dimensional data for quality assurance.
Yes, digital measuring tools (such as wireless radius gauges or the AI-Vision laser system) connect directly with Davi iRoll eXtreme CNC software. When a radius measurement is taken, data transfers via Wi-Fi or network bus to the control system. The iRoll eXtreme software compares actual measured dimensions against the target program and automatically adjusts side roll positioning (X, Y axes) to correct deviations without manual re-calculation.
