Testing: 3D Laser Scanner for Large-Scale Parts and Industrial Environments
Exact Metrology’s new Leica RTC360 Scanner offering is a portable coordinate measuring machine with 3D reality capture.
Comprehensive metrology service provider Exact Metrology, Cincinnati, Ohio, has launched the Leica RTC360 3D laser scanner. Manufactured by Swiss company Leica Geosystems and distributed by Exact Metrology, these portable coordinate measuring machines are designed to measure large-scale objects, including plastic pipe and tubing, housing components for large appliances and housing components for tractors as well as for plant management safety and efficiency and industrial, construction and vehicular accident environments.
This laser scanner uses 3D reality capture, a process of scanning and capturing any site, for example, factories, buildings, crashes and crime scenes, in a 3D digital model, combining measurements and imagery. The model can be used for design and comparison purposes in various situations, capturing every detail with to-the-millimeter accuracy. This technology combines one-touch operation with portability and speed to deliver high levels of accuracy, automation and the ability to create 3D environments in a matter of minutes.
Many industrial sites present inhospitable environments, where the health and safety of the employees and visitors are at risk due to temperature, corrosive materials, moving machinery and heavy objects. In addition, sites often have networks of pipes, tunnels, storage vessels and other structures that need to be examined. 3D reality capture permits complete site visualization for safety training. Site visibility also greatly improves plant management efficiency. Accurate measurements help designers create extensions without needing to visit the site and enhanced planning of workflow avoids disruptions.
Thanks to 3D reality capture, Building Information Modeling (BIM) experts save time and money as BIM processes become more efficient, from the accuracy of construction documentation to design and build quality assurance. The latest laser scanning technological developments improve understanding and documentation of the build environment through the use of millimeter-accurate laser scanning and High-Dynamic Range (HDR) imagery. By using 3D reality capture, previews of data and imagery are viewable onsite directly from a tablet, enabling scans to be checked and verified before going to the office.
The RTC360 3D laser scanner is ideal for professionals managing project complexities with accurate and reliable 3D representations. This scanner effectively combines a high-performance 3D laser scanner with Leica Cyclone Field 360, a mobile device app for edge computing that automatically registers scans in real time and Leica Cyclone Register 360, an office software that integrates the 3D model into the workflow. Additional features include capturing scans, including enriching HDR imagery, in less than two minutes, automatically recording moves from station to station and augmenting data capture with information tags.
The scanner’s portable design and collapsible tripod fit into most backpacks. Low noise data allows for better images, resulting in crisp, high-quality scans that can be used in a variety of applications. As part of the RTC360 solution, the Cyclone Field 360 links the 3D data acquisition in the field with the laser scanner and data registration in the office with Cyclone Register 360. The user can automatically capture, register and examine scan and image data.
Understanding the value of melt-volume rate.
The MFI test is used widely among the various segments of the plastics industry. The difficulty is that any two labs can easily come up with different results, making it difficult to determine whether a material meets a desired MFI spec. Here are some reasons why such discrepancies occur and what can be done about them.
Two areas where the melt flow rate test it is not useful are related to processing.
