Paper Abstract

A system for real-time surface deformations control during various types of laser processing is presented. It is based on a laser triangulation principle, where the laser projector generates multiple lines simultaneously. Three dimensional shape measurement of a surface is performed with a high sampling rate (80 Hz) and high accuracy (±7 μm). Results of steel-plate deformations are presented for laser bending, drilling and engraving. Laser based flattening process of previously deformed plate is demonstrated, where the measurement system is used as a feed-back control.
