Measurement system Instant measurement with the push of a button
UK — Measurement specialist Keyence has enhanced its dimension measurement system range of the IM-7000 series. According to the manufacturer, the upgraded systems offer greater speed, accuracy and ease of use.
Featuring a rotary unit allowing 360-degree multi-surface measurement capability for both turned and machined parts, the IM-8000 is fitted with a 20-megapixel CMOS — more than three times that of conventional systems — as well as a new algorithm for stable edge detection. In addition to the new CMOS, the screen is now larger and features enhanced resolution.
As well as standard metrics, the IM-8000 can perform a whole range of new measurements including symmetry, plane measurements, flatness, cylindricity, coaxiality and run-out, delivering new data visualisations including roundness graphs. This makes it suitable for parts with very complex geometries.
Able to measure more than 300 dimensions per part, the system starts to measure automatically as soon as the object is placed on the stage, which now moves at up to 80 mm/s. Highly precise dimensional measurements can be achieved in as little as one second, the company states. The wide field camera now features single field of view accuracy of +/-3.9 µm, compared with +/- 5 µm previously, with this camera and the high precision camera able to be used together in a single program.
No positioning or datum set-up is needed, meaning even inexperienced operators can get the most out of the system. Measurements can be rapidly set up with just a few clicks, and it is equally simple to set up virtual lines and points. All of the specified dimensions can then be measured at the touch of a button, with focus automatically adjusted. Measurement points are automatically identified, meaning the same measurement results are obtained each time, while automated focus adjustment prevents inconsistent values. Up to 100 parts can be measured simultaneously, drastically reducing measurement time.
The intuitive programming procedure enables quick and easy selection of the required measurement. An automated diagnostic function assesses the stability of each measurement point during programming, displaying any variations in measured items clearly and simply, making it easier and faster to create program settings.
Meanwhile, the automated measurement function can automatically detect measurement points on parts up to 300 × 200 mm 11.81'' × 7.87", even if these parts have not previously been measured. An integrated light probe can also measure features at specific heights. Program files can be rapidly located on the system by placing the QR code from the inspection report on the stage. This ensures correct file selection even in the presence of multiple file types.
Available options include an IM-specific calibrated graticule to allow users to perform their own verifications. Customers also benefit from regular software updates and extensive after-sales support wherever they are located.
