OGP combines touch and vision in flash bench top measurement range
OGP combines touch and vision in flash bench top measurement range
Keywords: Inspection, Metrology, Machine vision
The compact bench mounted elevating bridge design of the OGP SmartScope Flash, combination video-based non-contact and touch trigger contact measuring machine, has a 12.1 zoom lens giving up to 560 times on-screen magnification. In addition, by using through-the-lens coaxial illumination in conjunction with programmable LED under-lighting, a fibre optic ring light and SmartRing LED lighting, a perfect visualisation of the part being measured is ensured (see Plate 2).
Now available from Disc(GB) of Hatton in Derbyshire, the SmartScope Flash can be specified from a four model series comprising the 400, 600, 620 and 700. The series of machines refer to X and Y travels which range from 450 mm by 450 mm to 610 mm by 610 mm. In all cases, the vertical Z dimension is 200 mm, the scale resolution is 0.5 micron and maximum table load capacity is 30 kg.

Flash has been largely developed for electronic, medical, plastics and metal cutting industries providing the touch probe and non-contact capability to suit a wide variety of components. With the choice of programmable light sources, it ensures one of the quickest and flexible measuring solutions able to ensure high orders of consistency and repeatability while being very easy and quick to capture measuring data.
By incorporating the powerful OGP Measure-X 32 bit metrology software, Flash is able to perform high orders of image processing and auto-focus routines as well as geometric functions and incorporate touch probing into the measuring cycle.
Measure-X will also seamlessly integrate with OGP’s MeasureFit contour analysis software creating a “best fit” between template and measured results and provide real-time data transfer for reporting and SPC data gathering. A live display of measured features incorporates auto-scaling and colour coding.
The twin-column patented Z-axis carriage design of the Smart Space Flash uses a separate measuring scale for each column. Camera alignment and lens focalisation are permanently set to reduce maintenance and calibration. Because touch probe cycles are combined in the same program as non-contact measurements, a special probe to optics offset calibration ensures all sensors are referenced to the same co-ordinate system. The probe is detachable and as an option, a two or four position probe changing rack can be supplied with automatic docking.
Image processing is through 256 grey scale processing with 10.1 sub-pixel resolution.
