Press Release Summary:

May 10, 2013 -

Keyence's image dimension measurement system puts much faster in-process inspection within everyone's reach.

Timex is America's leading watchmaker and is present in more than 80 countries. Fralsen, its French entity, makes watch movements using three technologies — plastic injection moulding of small parts with very fine details; turning and cutting of parts such as wheels, pinions, arbors and rivets; and cutting and coiling of complex springs. These precision parts must be inspected with contact sensors (comparators, Cary equipment, feeler-spindles) and optical systems.

"We wanted more modern and more efficient optical inspection equipment. In other words, we wanted to be able to inspect more parts in less time," says Sylvain Scotto of Fralsen's Quality Control Department. "We also wanted a machine that could be operated by non-specialists and be able to log measurements."

The tolerances and accuracies are 15 µm for concentricity and ±10 µm for centre-to-centre spacings and distances. There are at least five critical points per part.

"With conventional inspection equipment, measurements took too long. As a result, we couldn't measure many parts and there was a risk of overlooking significant variations within batches. Before obtaining the IM Series, we used a variety of equipment. Our optical measuring device, which, although very accurate, is not very practical for quick measurements on a daily basis. Furthermore, it requires a high level of skill to operate. The shop microscopes provide accurate measurements, but are tricky to operate and severely limit the number of measurements and parts. In addition, a reference point for truing-up has to be created. Lastly, due to the sometimes long inspection times, our templates and projectors allow only a limited number parts to be measured and there is a risk of misinterpretation," adds Sylvain Scotto.

"The IM Series is simpler to operate, saves time and eliminates variations of interpretation of measurements. Results are conveniently displayed green (for good) or red (for bad). Keyence's solution allows several parts to be measured simultaneously. The size of the parts and the number of elements making up the program are the only limits. There is no need for manual truing-up because the system does it all by itself by recognising each part’s geometry. Furthermore, results can be saved and statistics tracked. Part profiles can be compared against master profiles imported from CAD files. As a result, we no longer need to position templates on parts and measure differences in shape by eye. The machine does so automatically and extracts an image of the contour showing the difference with the tolerance. All in all, measurements are fast and do not require special skills."

The new IM-6500 Series image dimension measurement system reliably measures features in almost no time at all. Simply place a target on the stage and press the button. Up to 99 points are measured in a matter of seconds with a repeatability of ±1 micron. Targets are found and measured regardless of their position or orientation and there is no risk of measurements being affected by variations in operator skill levels. Thanks to the iPASS shape detection method, the system determines the position and angle of targets, making measurements automatic.

"Getting to grips with the system was easy because all you have to do is adjust the focus and load the program for the part being inspected. All the QC technicians in the Quality Department use the machine for final inspection of parts before their placement in stock. The operators in the cutting shop also use it to measure certain parts during production. The programming is completely user-friendly. The faster inspection times enable us to track dimensions better and thus improve the quality of a large number of the parts we
deliver. What's more, we haven't received a single complaint from clients about any of the parts measured on the machine. For example, we use Keyence's IM-6500 to inspect the concentricity of every single cut wheel and automatically record the measurements," says Sylvain Scotto.
