Under the Radar

For inline inspection, Laser Radar devices are mounted to 6-axis robot arms that are located on each side of the production line. They automatically reposition the devices to inspect areas that are hidden from the line of sight of a single device location. 
With a need to focus on monitoring process quality during the manufacturing process, this laser radar system provides a unique alternative to the shortcomings of the traditional inspection methods.

Never Too Dense

With full CT automation, click and measure capability and dual tube technology, the Phoenix v|tome|x m system can perform analyses on an extremely wide range of samples, from high-resolution nano CT of low-absorbing samples to the high-power micro CT applications, such as engine turbine blades.
Advanced scanning technology can now perform 3D analysis of a scanned turbine blade, automatic pour porosity volume analysis on an aluminum casting, 3D measurements with nominal-actual CAD comparisons on a machined aluminum cylinder head – and more.

Replacing Tactile Probing with Laser Scanners

A close-up of one of the XC65Dx-LS laser scanners being used on a continuous wrist CW43 interface. Incorporating three lasers in a cross pattern, the XC65Dx-LS captures full 3D details of features and surfaces in a single scan.
This technical assessment explains how the new inspection methods for diagnostic measurement of sheet metal components and body-in-white assemblies at this Turkish automotive manufacturer involves cross scanners being used on coordinate measuring machines.

How Things Are Measured Today

A former hurdle with laser scanning was difficulty scanning highly reflective surfaces. This would necessitate spraying the object with a matte spray coating to eliminate obtaining reflective data and other extraneous noise. Modern laser scanners feature automatic real-time adjustment of sensor settings for each individual point along the laser stripe, effectively handling highly reflective surfaces or those with varying colors.
Retrofitting CMMs or articulated arms with new laser scanners is one affordable option among many that shops are considering.

Art Sculptor Uses Laser Scanning to Generate Revenue

Laser scanning projects a line of laser light onto the surfaces to be measured while a camera continuously triangulates the changing distance and profile of the laser line as it sweeps along. The position and orientation of the scanning head is continuously monitored by a highly accurate localizing device as the data is captured. Instead of collecting points one by one, the laser scanner picks up tens of thousands of points every second. This means that digitizing even the most complicated parts can often be accomplished in an hour or two.
NVision, Inc. (Coppell, TX) is helping sculptor Somers Randolph gain additional revenue by laser-scanning his creations and saving them as computer models that can be used later to reproduce the original works at any size on a 3D printer. For …
