The ColourBrain^® Edge 4.0 inspection system is the next step in the improvement of defect detection and the consistent revision of all user interfaces towards a system-wide and uniform look & feel in user interface. The system is used to inspect furniture parts in edge banding machines from various manufacturers. The detection of edge chipping, open glue joints, partially or completely missing edges and protruding edge bands are just as much part of the functional scope as the detection of geometric features such as grooves and drill holes and their differentiation from defects. The system can be used either in series production or in batch 1 production for defect detection and process optimization and ideally complements the ColourBrain^® Furniture 4.0 system.
