While this process is highly accurate and enables parts to be produced quickly and accurately, CNC cutting sometimes leaves burring along the edges, which may be sharp (a safety risk for workers handling the parts) and leave accurately cut components slightly outside the specifications. This issue is key for manufacturing parts that require smooth contact surfaces. The burr may also come loose and cause hang-ups or equipment damage in the downstream process. Deburring is, therefore, an important finishing process for ensuring that components are not left with rough or sharp edges.
Using this principle, we were able to develop a solution using a 3D vision sensor. This solution can be mounted on both fixed gantries and robotic arms as required, based on the size of the part and the coverage required.
As each part is scanned, a 3D point cloud image is produced that is then sent to ScanXtream for comparison with the original CAD drawing. This process flags any deviation from the pre-defined tolerance as a potential burr and notifies quality assurance staff immediately so that remedial action can be taken.
