In Process Identification of Workpiece/System Geometrical Deviations Based on General Purpose Robots and Laser Triangulation Sensors - Part 1: Conceptual Framework

Abstract

This paper gives a conceptual framework of a new class of metrological systems based on integration of general purpose industrial robot with laser triangulation sensor for contactless dimensional metrology. The paper has two parts. Part one considers conceptual framework where the system architecture is given, key aspects of the interface between two subsystems are considered, as well as a new methodology frames for signal processing and generation of partial or complete 3D digital model of scanned object with complex spatial geometry. For verification of practical applicability, laboratory installation is developed and experiments and practical functional testings are carried out. This paper also gives recapitulation of two feasibility studies: huge assemblies welding process robotization and forging press serving in the scope of flexible manufacturing cell for forging on MAXI presses. Evaluation and practical implementation are in the second part of this paper.
