Invention Reference Number
Detecting porosity in additive manufacturing (AM) parts is essential for ensuring quality and optimizing process parameters. This technology provides a method for identifying porosity in AM components by monitoring machining operations. Using external sensors and tool position data, the system pinpoints porosity locations along the machining pass. While destructive, this approach offers a fast and cost-effective alternative to traditional inspection techniques.
Description
This invention introduces a porosity detection system for AM parts that operates during machining by tracking spindle power, vibration, and tool position data. By synchronizing these inputs, the method can detect and map porosities within a component. Unlike expensive computed tomography (CT) scans, this approach provides an efficient and scalable solution for process refinement and quality control. It is particularly useful for rapid parameter development in AM, hybrid additive-subtractive processes, and evaluating preforms before final machining.
Benefits
- Cost-efficient porosity detection compared to CT scanning
- Rapid quality assessment during or after machining operations
- Integration with hybrid manufacturing for real-time defect monitoring
Applications and Industries
- Additive manufacturing process optimization
- Quality assurance in hybrid manufacturing
- Preform evaluation for casting and machining
