Laser Scanners

Never Too Dense

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 …

Parts, Cameras, Scan!

No preparation or complicated setup is required to operate the Go!SCAN 20 from Creaform. The scanner, which is ideal for delivering maximum resolution on smaller objects with intricate details, is up-and-running in less than two minutes.
Unprecedented speed, accuracy and ease-of use, combined with the fastest paths ever from art to part, make it tough for progressive shops to ignore an investment in 3D scanning. 

ERW Pipe Ovality Measurement

The Profile360TM In-Line Profile Measurement System from Starrett-Bytewise in final inspection produces an automated dimensional inspection report – an audit trail of the “as produced” quality for each pipe. The in-line measurement data can be used to fine-tune tooling set-ups during a diameter change. During production this system alarms whenever any parameter approaches the allowable limit so that an operator can intervene before a quality fault occurs.
The Profile360 In-Line Profile Measurement System from Starrett-Bytewise automatically measures pipe diameter and ovality for ERW pipe from 6 in up to 24 in OD at two locations: in-line before cutting, and in final inspection.

Sheet Metal Gap Measuring: Precision Replaces Approximation

Thanks to its unique swiveling capability, the CALIPRI device can be mounted alongside body gaps to analyze even the fold edges of sheet-metal body parts that form gaps – a huge technological advance compared to other methods that record gaps from only a few perspectives and calculate the missing data by mathematical approximation methods. They cannot analyze fold edges at all. 
The swiveling CALIPRI profile measurement device from NextSense revolutionizes gap and fold edge analysis to increase multifunctional profile measurement process security and reduce costs.
