Powerful and highly accurate coordinate measuring machines with computed tomography are now also available at moderate prices. The new Werth TomoScope®XS Plus enables the measurement of larger workpieces up to approximately 450 mm length and smaller objects with high resolution or reduced measuring time
The new coordinate measuring machine TomoScope® XS Plus with computed tomography from Werth Messtechnik in Giessen, Germany, provides twice the measuring volume of the TomoScope® XS. With Werth transmission tubes, high-resolution measurements are possible at high power in correspondingly short measurement times. The monoblock design of the tube, generator, and vacuum production makes the X-ray tubes nearly maintenance-free, providing extremely high uptime. The open design results in unlimited service life, as wear parts can be replaced if necessary. The other X-ray components have also been optimized to ensure a maintenance cycle of one year for the entire machine, as is usual with conventional coordinate measuring machines. The tubes are available with maximum voltage of 130 kV or 160 kV, covering a wide range of applications for plastic and metal workpieces.
In raster tomography, X-ray images of various workpiece areas are taken sequentially. The workpiece volume is reconstructed from the images at various rotational positions of the workpiece, and the patented sub-voxeling process is used to calculate the measurement points at the material transitions. This process allows larger workpieces of up to about 450 mm in length to be measured. Alternatively, smaller objects can be captured at high resolution individually or multiple objects simultaneously with reduced measurement time. The measurement results are complete workpiece volumes at almost any desired resolution in all coordinate axes (up to 60 billion voxels). The measurement point cloud allows both nominal-to-actual comparisons, by means of which problematic regions can be identified at a glance, and the measurement of geometrical characteristics.
The new machine is also suitable for in-line applications. This is made possible in part by the reconstruction of the workpiece volume in real time, in parallel with the measurements, by the fast analysis software, and by OnTheFly CT.
With the TomoScope® XS Plus, Werth Messtechnik presents another compact computed tomography machine with many new possibilities. The machine offers a cost-effective overall concept, with low space requirements and weight.
