IMTS 2016 Quality Assurance Pavilion Showcases New Class of Video Measuring Systems, New Technologies to Reduce the Cost of Quality
McLean, VA — Improvements in measuring systems, as recently established in optics and metrology grade cameras,will be featured in the Quality Assurance Pavilion at IMTS – The International Manufacturing Technology Show. The Quality Assurance Pavilion, located in the East Building at McCormick Place, showcases metrology equipment and systems that keep manufacturing processes on track, as well as the equipment that will check the accuracy of manufacturing equipment.
“Advances in optics and metrology grade cameras have led to a new class of Large Field of View (LFOV) video measuring systems that can image as much as 3 or 4 square inches of a part and make dimensional measurements instantly,” says R. Stephen Flynn, President of Optical Gaging Products (OGP®).
“IMTS 2016 showcases the latest advancements that take accuracy to a whole new level,” says Peter R. Eelman, Vice President – Exhibitions & Business Development, AMT – The Association For Manufacturing Technology, the parent organization of IMTS. “New systems at the Quality Assurance Pavilion show great strides in minimizing measurement uncertainty. Equipment and systems in the Quality Assurance Pavilion are great examples of the technical achievements we feature at IMTS.”
In terms of how far technology has come, “Massive improvements in computers and electronics over the last five to ten years have raised the bar for all quality and metrology systems — particularly non-contact metrology,” says Flynn. “The benchmark performance [speed and accuracy] of a video measuring system has easily doubled in the past ten years, while the cost has remained about the same.”
In addition, recent improvements in software and analysis tools allow coordinate measurements to be compared directly to CAD models. Very complex Geometric Dimensioning and Tolerancing (GD&T) scenarios can be evaluated instantly, and predictive models allow a tightly closed loop between CAD, CAM systems and dimensional measurement systems.
“These advancements help in three ways,” says Flynn. “First, measurement data is available quickly enough to make real-time process adjustments. Also, dimensions can be measured near the production line that previously required highly skilled and experienced toolmakers to measure in a lab. Finally, data from multiple measuring machines or multiple locations/suppliers can be normalized and compared directly to CAD models.”
As a result, operators with little or no metrology training now make measurements right on the shop floor. The benchtop LFOV systems allow parts to be placed randomly without fixturing and measured without a pre-programmed measurement routine. The system recognizes the part and measures the critical dimensions automatically. “As precision measurement becomes simple and easy, it becomes practical to do more of it, which results in improved quality and lower costs,” says Flynn.
Trends for IMTS 2016
There are several large trends that are impacting not only metrology but all aspects of the manufacturing chain. Model-based engineering (MBE) is one trend in which the CAD model is the central repository of all information about a part — not only its dimensions and material, but also important detail about the manufacturing process.
“Previously, CAD models described finished parts very accurately, but contained no information about how they should be made,” says Flynn. “Even tolerances were not embedded in the model but appended as text on the drawing, making for a laborious process of entering tolerances into CMM programs and GD&T evaluation software.”
Inclusion of this Product Manufacturing Information (PMI) in 3D CAD models now means that the measuring system has a priori knowledge of the manufacturing technique, as well as the part’s nominal dimensions and tolerances. “Measuring system programming time is vastly reduced, because all the parameters necessary for measurement are now in the CAD model,” says Flynn.“Load the CAD model, and 90% of the measurement set-up is complete.”
