Use of relocation device at scanning of polymeric material surface quality

Abstract

Nowadays, manufacturers and users of parts made of polymeric materials make increasing demands on surface quality of these parts. In order to fulfill these claims, it is necessary to use not only the quality measurement systems for surface quality inspection, but also suitable products that allow to set up the inspected polymeric component properly set up to the measuring system scanner. However, it is not sufficient. Due to the requirements of the customers or the production it is often necessary to repeat the surface quality measurement, which is more and more often done in 3D; that might be quite difficult. Except for special cases there should not be any marks done by the inspection workplace which might lower the inspected surface quality. Therefore it is not suitable to make mechanical marks such as scratch, ridge, etc. On the other hand, other types of marks done by non-invasive method, such as sticking paper marks, measuring cross, etc. is also not admissible as there might result in surface damage due to adhesive forces as well by mechanical or chemical processes. Thus it is necessary to take into account the fact that parts made of polymeric material can be so small that none of the above mentioned methods that are widely used nowadays cannot be applied just because of the dimensional reason. © (2014) Trans Tech Publications, Switzerland.
