Capture the real part on the machine and program on what is actually there.
The nominal CAD model is not always the part on the table. Worn components, formed parts and clamped assemblies deviate from it – and the program has to fit the real geometry. NetVision LaserTools AddOn Scan Module captures that geometry directly on the machine and brings it into the same environment in which the toolpaths are created.
A laser profile scanner mounted on the machine records the part while the machine moves it. The machine positions are read from the control at the same time, so every profile is placed with the full machine kinematics – table-side and head-side axes included – into the coordinate system of the part. No separate measuring station, no manual re-alignment between scanning and machining.
Scan lines are defined in the virtual machine: start and end positions are set with the tool centre point manipulator, pre-scan and post-scan lengths make sure the whole region is covered, and the scanned area is shown on the model before the scan runs. Scan feed and linking moves are parameters, and the scan program is simulated and collision-checked together with the rest of the job.
Scan data is cleaned where it is captured: outliers and flying spots are removed, noise is smoothed without rounding off edges, and the point count is reduced to what the task needs. Clouds are split into separate objects, cut back to the region of interest, merged and turned into meshes – all as steps in the model tree that can be changed and recalculated.
Best-fit alignment brings the scan and the nominal model together, restricted to the faces that really matter if required. Planes, cylinders and fillets are recognised in the cloud and rebuilt as CAD surfaces, free-form regions are fitted with NURBS patches. The result is geometry that cutting, welding and deposition strategies accept directly – the basis for repair on the actual part.
Same project, same CAD kernel, same digital twin.
NetVision LaserTools AddOn Scan Module records the part directly on the machine with a laser profile scanner and places every profile with the full machine kinematics. Scan paths are planned and simulated like any other operation. The cloud is cleaned, aligned to the nominal model and rebuilt into CAD surfaces that cutting, welding and deposition strategies use directly.
