1. Preparation: Cleaning the object, removing any debris, or applying coatings or markers to help with scanning or measurement.
2. Scanning: The object is scanned using a 3D scanner captures the surface geometry of the object as a point cloud or a 3D mesh.
3. Data processing: The point cloud or 3D mesh data is processed using specialized software to remove any noise, smooth the surfaces, and align the data to a common coordinate system.
4. Comparison to CAD model: The scanned data is compared to the CAD model to identify any deviations or differences. This helps to determine whether the physical object meets the design specifications.
5. Inspection analysis: The scanned data is analyzed to measure and verify the dimensions, tolerances, and features of the object.
6. Reporting: The results of the inspection analysis are compiled into a report that includes a summary of the inspection findings, any deviations from the CAD model or inspection criteria, and recommendations for corrective action if necessary.
GD&T inspection results typically use a set of symbols, such as position, flatness, perpendicularity, etc., to indicate the type of measurement being taken and the tolerance allowed. The inspection results are then compared to the GD&T design specifications to determine if the part or feature is within the allowed tolerance limits or if it needs to be rejected or reworked.
Mold maintenance: 3D inspection is an important tool for mold maintenance in manufacturing. By providing detailed analysis of the mold's geometry and identifying any deviations from the original design, 3D inspection helps to ensure that molds are functioning properly and producing high-quality parts. This can help to reduce downtime, improve efficiency, and minimize defects in the final product.
