Specifications and Acceptance Tests – 2

The use of multidimensional standards, such as spatial arrays of spheres on pins, is particularly efficient.  This  type of standard can be used to check many or even  all  of  the  lengths  required  to  test the  coordinate  measuring machine against […]

Specifications And Acceptance Tests – 1

Starting with the DIN EN ISO 10360 international series of standards, the Association of German Engineers (Verein  Deutscher  Ingenieure: VDI) has developed a guideline for acceptance testing of coordinate measuring machines  with  X-ray  tomography. This has  been  integrated  both  in […]

Spiral Tomography

Using spiral (better helical) tomography, the cone beam artifacts that arise in conventional cone beam tomography can be prevented.  This works by moving the measured object along the rotary axis as it rotates.  In spiral tomography, each layer of the […]

Dual-Spectra Tomography

In coordinate measuring technology with computed tomography, the dimensional analysis of work pieces made of  multiple materials is particularly challenging.  Multi-material work pieces are often metal and plastic components, such as assembled plug connectors.  The measurement task is typically to […]

Eccentric, Region of Interest, and Multi-ROI Tomography

Eccentric Tomography (a) now makes it possible to place the work piece arbitrarily on the rotary table.  This eliminates the laborious and time consuming alignment of the work piece, making measurements more convenient and efficient.  The measuring software automatically calculates […]
