New System Allows Dynamic 3-D Measurement At Climate Extremes

View Comments

At the Automotive Testing Expo that opened Tuesday in Novi, Clinton Township-based Dynamic Intelligent Solutions LLC launched a new, patent-pending process called ChamberCam that takes dimensional stability measurement of components under extreme climatic conditions to a whole new level, in terms of efficiency, reduced development time and cost and breadth of data acquired.

The ChamberCam system combines proven photogrammetry hardware and software with current thermal management technology to provide product engineers the unique ability to accurately measure parts in real time during thermal cycling in an environmental chamber.

“Until now, manufacturers could only measure a product before and after it was exposed to a predetermined temperature and humidity profile, making it difficult to know exactly how much and when a part might change under various conditions,” said Larry Arnone, vice president of DIS. “With the ChamberCam process, we offer the ability to capture dimensional data at hundreds of points on the product — up to 15 times per second — throughout the actual climatic testing. This provides the engineer with more information than was ever available, and potentially eliminates days or weeks of costly testing, development and downstream engineering time. The ChamberCam system is groundbreaking, not only in the kinds of precise measurement data that can be captured, but also in the way the data is delivered to the customer. DIS can deliver data to the customer in a familiar fashion, as well as providing much more data including time, temperature and humidity in pictures, charts, video and 3-D point data showing direction of the point movement for each measurement.”

DIS provides customers with viewing software at no additional cost, allowing them to review testing results and present data to their colleagues, superiors and customers. This data is instrumental during root cause analysis and problem-solving engineering and design flaws efficiently, as an engineer can analyze up to 100 times more data — including previously unobtainable data — in less time than it takes with today’s process.

The system employs proven, robust measurement principles (photogrammetry), technology, data acquisition software and hardware, digital cameras and an environmental management system that enables the high-speed, high-resolution digital cameras to operate inside thermal test chambers. This closed loop system can also be used as a mobile system at a customer facility. The setup, calibration and measurement process of the system is very robust and easy to use.

The ChamberCam system:
* Slashes cycle time of engineering evaluations;
* Reduces guesswork, repeated testing and downstream engineering;
* Eliminates the need for traditional coordinate-measuring machine services and associated time delays;
* Provides real-time point measurements under temperature or in motion that were previously unavailable;
* Is accurate to 35 to 45 microns and can capture data up to 15 times per second;
* Can withstand temperatures from -77 degrees Celsius (-107 degrees Fahrenheit) to +177 degrees Celsius (+351 degrees Fahrenheit) and up to 95 percent relative humidity;
*Offers almost unlimited test data sets and point comparisons in video, pictures and 3-D point data charts for quick evaluation and analysis; and
* Uses software that makes results presentations a snap.

DIS is offering the ChamberCam service at its testing partner, Primetime Testing Laboratory, Inc., in Clinton Township. Ideal for validating automotive interior components such as instrument panels, door panels and consoles, the process can also be used for other products and markets where dimensional stability at temperature or in motion is critical.

DIS is now scheduling tests using the ChamberCam process at Primetime Testing Laboratory’s Clinton Township lab. To schedule a demonstration or product testing, manufacturers should call Jim Arnone of DIS at (586) 468-3939 or e-mail jarnone@dynamic3dmeasure.com.

DIS is a provider of measurement services when testing under extreme climatic conditions for the automotive, aerospace, government, marine, recreational vehicle and consumer goods markets. The DIS system utilizes optical camera-based 3-D measurement for superior accuracy. More at www.dynamic3dmeasure.com.
