Werth Tomoscope HV computer tomography coordinate measuring machine
MacroScience Technology (MST) MSX Computed Tomography (CT) series
Hexagon's Holmberg - Enquiries across the board
Control 2007 exhibition, held in Sinsheim 8-11th May, saw a number of exhibitors showing development in Computer Tomagraphy systems. Non destructive testing, inspection and dimensional measurement using computer tomography (CT) techniques are moving out from the laboratory onto the production line.. CT systems are beginning to be seen in quality control applications, such as in component metrology, defect/porosity analysis, wall-thickness analysis, actual/nominal comparison, rapid prototyping and reverse engineering.
Werth Messtechnik introduced the TomoScope HV at Control 2007. Based on the smaller TomoScope, the TomoScope HV can measure parts up to 40 kg and has an extra large 2,000 x 2,000 pixel X-ray sensor. With a tube voltage of 225 KV, it can measure high-density components (such as aluminum, steel, titanium, elastomers, hybrid plastics, 2K, ceramics and fibreglass-reinforced plastics.
Werth’s patent-pending process (auto correction) “guarantees” accurate measurement data with traceability of tomographic measurement results to the standards of the PTB (Physikalisch-Technische Bundesanstalt - German Federal Physical and Technical Institute) in compliance with ISO 10360.
Using grid tomography, the Werth TomoScope HV can measure components with lengths up to 700 mm. Components with lengths and diameters of 350 mm can be measured “in the image” without moving the linear axes.
Also introduced at Control 2007 is an updated version, 7.30, of WinWerth software, featuring many new functions with significant improvement of the 3D CAD Module. The program now has full 3D functionality, such as 3D Bestfit and 3D-CAD-Online/Offline, and has expanded capability to work with large point clouds in computer tomography or laser scanning.

Also showing a computer tomography system was Zeiss IMT with its METROTOM 1500 CT system for industrial quality assurance. The METROTOM 1500 is calibrated with proven methods using calibrated standards. With this procedure, Carl Zeiss guarantees the specified accuracy of the measuring result without additional contact or optical reference measurements. As a result, a key benefit of METROTOM – the omission of an additional measuring run with other sensors – is fully utilized. The results are traced to the linear standard of the PTB (German National Metrology Institute) using calibrated standards and standardized methods. Carl Zeiss state they have submitted a patent application for the procedure used to calibrate METROTOM.
MacroScience Technology (MST) presented its MSX Computed Tomography (CT) series. The entry model of this product line is the MSX CT300. With this system, MacroScience provides a high resolution CT system with a fast reconstruction algorithm, enabling image 3D reconstruction online during the measurement. Due to this fast reconstruction, the system can be used both in a laboratory for non destructive testing and in production for random inspection of components and devices. By adding the MSX CT series to its product portfolio, MST now covers the whole range of X-Ray inspection.
Good Show for Hexagon
“Control has been a good show for Hexagon”, said Per Holmberg president of Hexagon Metrology Europe when interviewed by Quality Manufacturing Today at the exhibition.
“Enquiries were spread across Hexagon’s extensive product range, including portable CMMs, sensor technologies and software.We also had enquiries for large gantry measuring machines.”
“New developments seen at Control? a lot of new software companies coming in, a lot of activity in the non contact sensor area, not just by Hexagon but by other companies and of course developments in sensor technology, particularly with Hexagon’s range of sensors and probes, such as the new robotic rotating stylus probe. “
Another show development was the presence of Chinese companies exhibiting own brand CMMs complete with software and systems, some of them with familiar looking designs. “Its a natural development, says Per Holmberg, “They have adapted the knowledge, they have experience and they have the capabilities - as is happening in other markets.” Hexagon are set up globally with global products operating in NAFTA, Europe and Asia. Hexagon follows growth markets, currently happening in the Asian markets and it is Per Holmburg view that there is space enough for Chinese and others to service these areas.
And the move of the Control Exhibition to Stuttgart next year? ”Its got good access, airports and so on but its going to cost more.”
