From the scan of the worn blade to the verified deposition program.
Blade tip repair shows why that matters. No two worn blades are alike, the nominal model describes the blade as it was built rather than as it comes back from service, and the new material has to follow a thin, twisted profile exactly. NetVision LaserTools takes the repair from the scan of the worn blade to the verified deposition program in one environment.
A laser profile scanner on the machine records the blade in its clamping, and every profile is placed with the full machine kinematics into the coordinate system of the part. The point cloud is cleaned of outliers and noise without rounding off the thin edges, meshed and aligned to the nominal model by best fit – restricted to the undamaged faces if required. Scanning and repair happen in the same setup, so no re-alignment error creeps in between the two.
The damaged tip is cut back along the blade itself: the split is placed at a defined distance along the medial curve of the tip face, measured from a reference axis and turned perpendicular to the blade profile. Meshes are repaired, holes are closed and CAD surfaces are rebuilt from the scan where the nominal model no longer fits. What remains is a clean base for the build-up – on this blade, not on an idealised one.
Medial path deposits along the centre line of the blade profile, thin wall build creates single-bead walls from constant offsets, and multi-axis cladding and geodesic offsets cover wider sections along the surface itself. A dedicated BLISK build strategy and circular patterns repeat the repair across a complete rotor. Operations are parametric and recalculate when the geometry changes, and saved default parameters and project-wide technology make every blade start from proven values.
The programmed deposition is simulated as real geometry, layer by layer, so gaps, overlaps and unreachable regions of the tip become visible at the programming station. The program runs on the digital twin of the machine with nozzle, head, clamping and blade; collisions, axis limits and reachability are checked move by move, and every move stays linked to its NC block in the integrated editor – so a correction is made and re-checked in the same place.
Same project, same CAD kernel, same digital twin.
NetVision LaserTools Add On Blade Repair scans the worn blade on the machine, aligns it to the nominal model and cuts the damaged tip back along the blade profile. Medial path, thin wall and multi-axis strategies rebuild the tip, the build-up is simulated as real geometry, and the program is verified on the digital twin of the machine before the first bead is deposited.
