It is easy to trace the evolution of 1-dimensional measuring tools (calipers, micrometers, feeler gages, etc.) to 3-dimensional surface mapping tools (CMMs, both stationary and portable). While the 1-D gages give precise measurements on standard geometrical shapes, they are very inflexible and inadequate when measuring features on complex surfaces. Three-dimensional CMMs, on the other hand, provide a great deal of information on surface geometries and contours, which are great for verifying part shape, but are cumbersome and time consuming to use for measuring simple features, such as the gap between two complex panels.

2-D Laser Contour Inspection
The LaserGauge® bridges the gap between these two very different inspection methods. With a combination of portability and flexibility through advanced algorithm definition, LaserGauge® technology fills the void left between mechanical gauging and CMMs. Though unable to acquire 3-dimensional part information, rapid on-line inspection of 2-dimensional features, such as gap/flush, welds or edge radius, becomes possible with almost no setup time.

 

ADVANTAGES OF LASERGAUGE®

Since the LaserGauge® bridges the gap between mechanical inspection tools and 3-D CMMs, it brings advantages from each of the types of gauging: portability, flexibility and traceability.

Portability
The portability of the LaserGauge® is attributed to its simplified technology coupled with small-form-factor embedded processors which yield a very compact, full-featured package. Standalone DSP systems weigh less than 1 pound (0.57 kg), and controller-based systems providing enhanced graphics and functionality weigh as little as 4 pounds. Utilizing battery power, the inspector can take the LaserGauge® to the part to obtain quality measurements while it is still in the manufacturing process.

Flexibility
The LaserGauge® sensor digitizes the contour of the surface and this digitized contour is processed utilizing predefined algorithms to “virtually” take measurements from the scanned surface. Calculations are performed virtually on the scan, so the number of possible algorithms is almost limitless. Options are also available to take measurements manually from the scan data in much the same way that dimensions are measured on a CAD system.

Traceability
The value of the final data obtained from the contour scan is judged by its traceability to known part or assembly math data or engineering drawings. Since the algorithms acquire the measurements using predictable and known methodologies, measurements can be configured to match engineering requirements. Because the acquired data matches engineering requirements and is acquired with definable methodologies, data can be fed back into process to make constructive changes for enhanced product quality. And all of this is done with a portable inspection tool.

Stability
The critical components of the LaserGauge® are packaged into a very rugged internal mount that holds the relative position of the laser and imager to precise tolerances. This, in turn, is packaged into an external housing that protects the optics and electronics of the sensor. These two features result in a very rugged sensor design, capable of withstanding major shock (such as impact to a concrete floor) without damage or affecting the measurement accuracy of the system.
