Paper Abstract

In the manufacturing of seamless tubes in a rolling process mandrel bars are used to produce thickwalled tube blanks. The quality of the surface inside of the tube blanks and the seamless tubes strongly depends on the surface area of the applied mandrel bar. Up to now the surface quality is inspected manually. Through automatic inspection the surface area can be continuously observed and therefore defects can be recognized and corrected in early stages. A method of solution for an inspection system, which is based on the application of fuzzy logic, has been developed. This method determines and reports the quality of the mandrel bars surface area. So the mandrel bars can be termed as `smooth,' `good' and `rough.'
