Modern Machine Shop 287 IMTS 2018 Inspection and Measuring Burr Detection System Features Robotics, Machine Learning All Axis Robotics is featuring an automated burr and foreign object debris (FOD) detection inspection system. This turnkey system combines optics, multi-axis and rotational movement, and software to automatically iden- tify, detect, locate/map, and guide operators to repair or remove burrs or FOD on manufactured workpieces. As delivered, all systems include a six-axis robot with controller systems and basic robotic pedestal. The system works with metals, composite materials and plastics. It also detects abnormalities in the fabrication process, such as tool mismatches and over-etching, by comparing what is detected to what is expected via system software and 3D CAD models for feature and characteristic identification. The system software uses machine learning and pattern recognition to identify both regularities and irregularities in data, always comparing to CAD models and operator overrides. The system can be trained to recognize different types of FOD, debris or burrs and this information can be added to the learning database for future recognition and filtering. The size of FOD, debris or burr objects can be mea- sured and filtered as a "pass," "fail," or "indeterminate (learn)," depending on the criteria established by the specification. Indeterminate findings can be submitted for manual intervention to determine future "pass" or "fail" criteria. Once detected, the optics can inspect a feature of interest from a range of Cartesian coordinates. The system is said to improve the speed of parts inspection by eliminating time-consuming manual inspection. Accuracy is improved through a consistent inspection methodology controlled by software with the ability to consistently inspect difficult-to-view locations. The system improves repair of workpieces by identifying and mapping locations of FOD and burrs for remediation. Identification, classification and tagging of burrs is con- sistent on every part, the company says. | All Axis Machining and Robotics Integrator | North, Level 3, Booth 236165 Thermal Imaging Offers Efficiency in EB-PBF Defect Evaluation LAI International's Thermal Imaging Rendering & Anal- ysis (TIRA) technology has been developed to enable quality analysis for electron beam powder-bed fusion (EB-PBF) additive manufacturing. The technology ana- lyzes the internal material of additively manufactured parts and is meant to be a more efficient alternative to CT scans and X-rays. The technology uses in-process, near-infrared images collected during the build to conduct in-depth analyses on possible indications. Quantitative studies have shown the technology's results to be consistent for location, quantity and size of defects, the company says. This service is offered with all of the company's EB-PBF builds. LAI International provides a report in its post-build quality package that includes a list of defect indication location, sizes and quantities for each individual part, as well as a corresponding model to visualize the exact location and shape of each indication. | LAI International Inc. | North, Level 3, Booth 236374
