Generating of STL Models of Plastic Part and its Effect on the Final Accuracy in Computed Tomography

Abstract:

Measurement of industrial parts is very important for current production. There are many different methods (contact and non – contact) for part ́s control. Every of those methods have some advantages and disadvantages. The biggest problem was found in measurement of very small parts or complex parts which have some inaccessible places. The solution was implementation of X-ray technology into the measuring process. It is called computed tomography or metrotomography (connecting metrology and tomography). This technology finds application in many different fields, especially in the automotive industry. The result of the method is cloud of points or generated STL models which are suitable for use in other software for evaluation. However, there is still question of the method accuracy and accuracy of the generated STL models. This paper is dealing with scanning of plastic part with X-ray technology, generating of STL models by different methods and their accuracy evaluation.
