Simple, 3D option to enhance InspecVision’s Planar 2D Measurement System.
While 2D sheet metal production has become more reliable, 3D or 2½D sheet metal production is still susceptible to errors such as bending spring-back, press-brake programming errors, missing forms, louvres and inserts.
The demand for these 2½D parts is increasing and it is now common to see punching machines create parts with louvres, forms, inserts and even small folds. Even when the part is nominally flat it is quite common for the features punched in the part to deform the metal creating a relatively unflat component.
The InspecVision Opti-Scan 3D is a highly capable 3D scanner, however adoption of a full 3D scanning system on the shop floor can be daunting.
A low cost and easy to use alternative is needed
The system should;
The SurfScan is a high resolution projector which mounts onto the existing Planar vertical column.
The projector shines structured lights onto the part which are then imaged by the Planar’s camera to create a 3D scan of the upper surface of the part. However rather than focusing on purely 3D inspection the SurfScan is primarily designed to augment the existing 2D scanner and provide a powerful yet easy to use 3D or 2 ½D inspection capability.
Many punching machines do not produce completely 2D parts.
The parts have forms, louvres, small bends, pins etc. The SurfScan integrates seamlessly with the Planar 2D automatic inspection software to allow accurate inspection of both the parts 2D shape and its 2 ½D features with a single click.
The features included in the Planar software include;
If 2 ½D is not enough for some jobs the system can be turned into a full 3D inspection system.
The point clouds or meshes created by the system can then be loaded into free and readily available 3D inspection software for comparison against a 3D solid CAD model, such as step or iges.
The point clouds are also compatible with packages like Geomagic Control, Control X, Polyworks etc. Parts with complex geometry can be scanned from several angles to create a complete scan of all visible surfaces
