Industrial CT technology is improving very quickly. While a few single CT slices could take hours to generate years ago, it is now possible to reconstruct complete 3D models with billions of Voxels (three dimensional Pixels), in just seconds. This opens the door for numerous new applications like 3D inline automatic defect recognition, 3D reverse engineering, rapid prototyping, 3D metrology, and so on, so it has now become a very competitive technology for 3D scanning.
Our last article (published in June’s QMT) looked at the measurement considerations that will allow you to make better measurements in the workplace, outlining the advice NPL gives to measurement professionals at the preliminary stages of the measurement process. In this article we examine the next step of the process, when professionals are preparing to take a measurement.
Dinesh Prajapati, a director of Leicester-based subcontract machinists, Nisan Engineer, takes the view that there is no point machining a component if you cannot check that it is within tolerance. His problem though was that parts were becoming increasingly difficult to inspect after the company which traditionally used 3-axis CNC machining centres, installed a 4-axis horizontal-spindle model in 2013 and a 5-axis vertical machining centre in August last year.
Contract manufacturer Express Engineering has installed a massive co-ordinate measuring machine (CMM) to undertake the rapid and accurate inspection of large oil and gas components. To enable oversize components to stand upright when being measured, the CMM was modified by an extended Z axis and a 1.2m diameter hole bored through its granite measuring table.
Ardor Engineering Ltd specialises in the production of high-quality, precision machined components in materials that include superalloys and other exotics for customers in sectors that include nuclear, oil & gas and defence. recent move to new premises doubled the company’s floor-space, allowing it to add new CNC machine tools and increase output.
Optical scanners provide point-cloud data collection, portability and speed and will play a significant role in the future of quality control for production line metrology. Being readily available and using fast-developing technology the capabilities of 3D optical scanners are not yet fully understood and scanners are known to have difficulties measuring certain surfaces and geometries.
UKAS accredited Roxspur Measurement & Control Ltd (RM&C) provides both on-site and in-house calibration to either UKAS or national standards. The company provides full certification of a range of disciplines including temperature pressure, flow and electrical parameters.
DEKRA Industrial is one of the leaders in the prevention of industrial and occupational hazards in France and Europe. Its expertise in identifying and assessing hazards is instrumental in risk prevention for a variety of companies.
Combining pumps, intensifiers and articulated cutting heads capable of producing 3D parts, CNC waterjets are highly engineered pieces of capital equipment. At the heart of the process though, is the waterjet orifice—an assembly often built around an industrial ruby, sapphire or diamond to concentrate and maintain the strength of the waterjet cutting stream. “Without the orifice, the entire system is essentially useless,” says Ted Jernigan, president of Diamond Technology Innovations located in Olympia, Washington.
The measurement solutions provider has supplied a range of equipment to the National Physical Laboratory based at Huddersfield University to support its projects with businesses in the Yorkshire and Humber area. PL Huddersfield has added a pair of Hexagon Metrology co-ordinate measuring machines and a ROMER portable measuring arm to its busy facility in a bid to boost research and development capabilities, CMM part programming and training services.
