Complete external and internal measurement – X-ray tomography in coordinate metrology

<p>BASICS PART 3 In coordinate metrology, tactile and optical sensors and X-ray computed tomography are predominantly used. X-ray tomography machines differ in their basis and components such as X-ray source, rotary axis and detector as well as in their software and thus in their properties, the basic understanding of which is helpful for optimising their use. Spatially extended objects, including their internal structures, can be fully captured by metrology.</p>

Flexible and surface-independent– Tactile sensors in coordinate metrology

<p>BASICS PART 2 Tactile and optical sensors as well as X-ray computed tomography are predominantly used in coordinate metrology. Tactile sensors differ in their functional principle and structure consisting of mechanics, optics, electronics and software and thus in their properties, the basic understanding of which is helpful for optimising their use. Tactile measurement is largely independent of the surface properties of the objects to be measured.</p>

Non-contact and fast – Optical sensors in coordinate metrology

<p>BASICS Part 1 In coordinate metrology, tactile and optical sensors and X-ray computed tomography are predominantly used. Optical sensors differ in terms of their functional principle and structure consisting of mechanics, optics, electronics and software and thus in their properties, the basic understanding of which is helpful for optimising their use. Sensitive workpieces and those with small features can also be measured without contact.</p>

Multi-sensor or X-ray tomography – The measuring task determines the choice of coordinate measuring machine

<p>For efficient use of coordinate metrology in quality assurance, the measuring machine of the right accuracy class and size must be equipped with the appropriate sensor or multi-sensor systems. It often makes sense to combine non-contact sensors with tactile sensors. However, the suitability of the sensor for the measurement task depends on various criteria.</p>

Micro tools and topographies in all facets

<p>Micro-mills and special tools made of carbide or diamond are sometimes only a few tenths of a millimetre in size and have CUTTING EDGES with perfect sharpness and radii of just a few micrometres. The measurement of such geometries is one of the greatest challenges for non-contact and tactile coordinate metrology.</p>

Multi-sensor systems for micro-features – Metrology for fuel injectors

<p>For over ten years, Continental AG has been using machines from Werth Messtechnik GmbH, Giessen, for the measurement of fuel injection nozzles worldwide. The image processing sensor technology initially used was soon supplemented by the patented Werth fiber probe and later by computed tomography. This enables the highly accurate measurement of size, mould and Roughness and guarantees the traceability of the measurement results.</p>
