Optical Bi-Sensorial Measurement System for Production Control of Extruded Profiles

摘要

Extruded profiles are semi-finished products - made out of steel, brass, aluminum, polymers - which are appointed for wide applications in manufacturing of technical products. Today used optical sensors in process control can only measure accurately a two-point information of the part or with dense pointclouds at concave zones but with lower accuracy. It is to serve with a reliable conception to combine both advantages as well as suitable methods of analysis for the in-line inspection of concave profiles. The target uncertainty of less than 0.1 mm at every section of the profile has to be met.
