Objective
Waviness is an important parameter as, if it is above defined limits, the steel user does not accept the product because it causes scrap or bad quality in the further processing. But, except for high glossy surfaces, it is mostly not eye visible before painting. So, an on-line measuring system is of great interest for it will measure the waviness not only at the head or tail of coil but all along it.
The new system will be developed on the base of CRM on-line microscope integrating high speed components, stitching algorithms and multiprocessor implementation.
The project will cover the validation of the technique in laboratory and in industry. Industrial partners will be deeply involved in the industrial validation but also in the analysis of the database so constituted. This database, regrouping waviness measurement and production parameters, will be analysed to define guidelines to improve the process and so the product quality.
