2D ADAPTIVE MEASURING FOR FREE SURFACE WITH 3D PROBE COMPENSATION

Abstract

Abstract: A 2D adaptive measure method for free surfaces based on Bézier curves is developed, the measuring experiments are carried out focused on comparison of our new method with traditional equal step measuring. In order to process the scattered data from adaptive measuring, a 3D probe compensation method based on triangulation has also been developed, both compute simulation and practical experiments are performed, and the results show potential application of the methods in the laser intelligent manufacturing system.

Key words: Bézier method, Triangulation, Adaptive measuring, Free surface, Probe compensation, droplet transfer, high nitrogen steels, shielding gas, welding porosity, hybrid welding
