Omco Group Glass moulds produced faster and less expensively using modern multi-sensor metrology Nikon Metrology laser scanner cuts project approval from 2 weeks to 24 hours Omco Group, the largest manufacturer of glass container moulds in Europe is leading the way within its industry by using laser scanning to digitize customers’ bottle designs, shortening the lead-time from receipt of order to delivery of the finished moulds. Manufactured by Nikon Metrology, a pioneer in 3D laser scanning and part of the renowned Nikon group, the digital line scanner is fitted to a coordinate measuring...

Apart from speed and cost reduction, a further advantage of automated inspection is increased accuracy and elimination of human error. Alexandru Geant a, Quality Manager at Omco ˘ model then had to be evaluated and passed off at the other end. Overall, it used to take up to 14 days to receive any changes needed to the design plus the go-ahead to start producing the set of moulds. “Now, we simply scan the resin facsimile from several angles on the CMM using the LC50Cx scanner mounted in a Renishaw PH10M motorized indexing head. The resulting point cloud data, an exact digital copy of the...

Final inspection throughput of a glass bottle mould is tripled by using CNC multi-sensor CMM. The importance of these measurements cannot be overstated. The preliminary mould produces a small, solid glass parison (a preshaped mass of glass) that is blow-moulded to produce the bottle. Measuring parison volume is critical, as too little glass might lead to the bottle breaking and too much would result in enormous wastage of glass during subsequent mass production. Interestingly, mould volume calculation was the test that Omco gave to several metrology system suppliers before placing the...

Automated nikon photo-microscope supports world-leading rock analysis Computerized PETROG inspection system provides better understanding and faster analysis of rock samples Founded in 1997 by Dr Barrie Wells and his partner, Mark Gorst, Conwy Valley Systems in North Wales has become a global leader in the supply of computerized photo-microscopy systems for inspection, statistical analysis and classification of rock samples to assist oil and gas exploration. Known generically as a digital petrography tool and marketed under the trade name, PETROG, the inspection system is powered by a Nikon...

The heart of a PETROG system is the low profile, motorized, rotating stepping stage, seen here fitted to the Nikon microscope. by manual tick-box recording of results. The user has a much better understanding of the rock sample, its constituent minerals, oil-bearing capacity and extraction potential. PETROG displays results almost immediately on the screen and has the added advantage of storing all photographic images for future reanalysis, if required. The PETROG system comprises a Nikon Eclipse 50iPOL binocular microscope fitted with a Nikon Digital Sight DS-Fi2 5-megapixel camera which...

A photo-micrograph of sandstone from an oilfield, with the pores highlighted by the addition of blue dye. A photo-micrograph of a concrete sample taken by CEDEX, Spain. The pores appear yellow because the concrete is impregnated with epoxy and a fluorescent dye has been added. The porosity in this sample is quite moderate. The aggregate is limestone, which can be granitic, while the brownish matrix is cement paste. Picture height is 13.6 mm. The construction industry also benefits from PETROG, since a sample of man-made concrete can be analyzed as easily as natural rock. It is an important...

University of Leuven applies metrology CT to research geometrical accuracy of inner and outer features of industrial components Complex manufacturing drives the need for internal inspection Many components and assemblies have internal features that are difficult to inspect nondestructively, as conventional metrology requires them to be sectioned. Examples are a hollow hydroformed camshaft, a 3D printed mould with conformal cooling channels, or a plastic injection moulded electrical connector with metal inserts. Now, the PMA division of Leuven’s university is using X-ray Computed Tomography...

Prof Jean-Pierre Kruth, full professor at the Production engineering, Machine design and Automation division (PMA) within the department of mechanical engineering at Katholieke Universiteit Leuven. Such complex products presented us with a challenge, as it is impossible to nondestructively inspect the internal features without X-raying the parts. Prof Jean-Pierre Kruth , University of Leuven One of the PMA division’s X-ray machines, a 225 keV model XT H 225, includes a microfocus X-ray source, linear scales, better cooling and other enhancements that provide increased accuracy, making it...

The XT H 450 X-ray source is suited to scanning small castings to gain an insight into the inner details of the part. The curved linear diode array detector (CLDA) optimizes the collection of X-rays by eliminating scatter phenomena that typically corrupt 2D radiographs of blades and other metal parts. depending on the application-, measuring uncertainty (maximum permissible error) both internally and for outer dimensions of the part can be below 10 microns using the Nikon Metrology CT system. This means, its accuracy lies close to that of a typical coordinate measuring machine. For example,...
