As well as exhibiting a cross section of its latest non-contact and multi-sensor SmartScope metrology systems at MACH 2010, visitors to Hall 5, Stand 5261 will be treated to the first UK demonstration of OGP’s new TeleStar TTL (through-the-lens) sensor.
TTL technology is breaking down conventional barriers to high resolution surface contour measurement. It features an innovative and patented interferometric range sensor design that works by diagnosing the properties of two or more light waves by studying the pattern of the interference created when overlapped.
This design brings many benefits including long working distances and the ability to measure both diffuse and specula surfaces to the same high accuracy. An additional advantage is that the sensor can measure deeply recessed surfaces and steep contours, such as a complete hemisphere, through apertures as small as 0.25µm. In fact the sensor can even measure when 60% of the beam is clipped.
TTL is available for use on all of OGP’s Telecentric optical systems within the SmartScope family of coordinate measuring machines. Among the machines featuring TTL at MACH will be the SmartScope Vantage 300, a no-compromise four-axis part measurement system that uses a combination of video, touch probe and laser, with the ability to switch reliably between measurement systems during the same set-up.
At the show, the Vantage 300 multi-sensor measuring machine will be busy measuring aerospace components. The system’s optical sensor will be used throughout its zoom range to measure 2-dimensional geometry, while the touch probe will measure 3-dimensional features and the laser probe will collect surface information – all of this will be performed in a single set-up to generic frame of reference.
The process will be aided by OGP’s powerful yet intuitive and easy-to-use MeasureMind 3D software which allows fully automatic measurement routines to be programmed in minutes. Furthermore, sensors can be switched with the click of a button and data outputs can be customised to meet personal reporting formats or used by seamless analysis packages to compute 3D surface profiles, part to CAD comparisons, SPC or reverse engineering routines.
The Vantage 300 also features OGP’s patented SmartRing surface illumination – vector light that gives total control of lighting angles, making it easy to pick out important features for repeatable and accurate optical probing.
SmartRing will in fact be featured on all of the OGP models demonstrated at MACH, including the SmartScope CNC 500, a compact, large volume CMM of travel-bridge design with the versatility to measure 3D geometry using a combination of probes, single or dual rotary axes and software applications.
Measuring general engineering parts at MACH, the CNC 500 will feature OGP’s Measure X software, which has the functionality to support everyday metrology tasks including the automatic measurement of points, lines, planes, circles, distances, cones and spheres.
Completing the MACH line-up will be a SmartScope Flash 200. With more than 2000 systems installed worldwide, SmartScope Flash is one of the most important and popular video and multi-sensor measurement systems available. Its compact, robust design meets the measurement needs of manufacturers in a broad range of industries and is ideally suited for shop floor inspection.
The Flash 200 at MACH will feature TTL sensor technology and both Measure X and MeasureMind 3D software. It will be demonstrated measuring automotive components.
All visitors to the stand will receive a warm welcome from OGP experts who will be on hand to discuss any requirements. Visitors may be interested to note that a SmartScope Flash 200 will also be present on the stand of Unicut Precision (Hall 5, Stand 5171a). Unicut, a leading UK subcontract manufacturer, will be using the Flash 200 to measure a selection of its precision machined components.
"We evaluated accuracy, repeatability and speed of throughput in four competitive systems and the OGP system came out well ahead."
